DUN LAOGHAIRE, Ireland and TEXCOCO, Mexico — Irish humanitarian aid agency GOAL has joined CIMMYT (the International Maize and Wheat Improvement Center) in the fight against fall armyworm, a devastating insect pest that experts say threatens the food security of millions of people in Africa.
The fall armyworm has caused significant damage to maize crops in sub-Saharan Africa since its arrival to the region in 2016.
A study on the impact of the fall armyworm in eastern Zimbabwe reveals that nearly 12 percent of crops are lost annually due to the infestation. And the study states that if the problem spreads throughout the entire country tonnes of grain to the value of $32 million could be lost.
GOAL Zimbabwe has now teamed up with CIMMYT to identify conditions that promote fall armyworm infestation in order to educate farmers on best practices to fight the problem.
Regular weeding, conservation agriculture, use of manure and compost, and ending pumpkin intercropping have been found to help prevent infestation.
Mainassara Zaman-Allah, co-author of the study and abiotic stress phenotyping specialist at CIMMYT said, “Given the limited coverage of the study in terms of area and season, it would be interesting to replicate it all over the country through the involvement of governmental agricultural departments, so that we get the full picture around the fall armyworm problem at a larger scale.”
Gift Mashango from GOAL Zimbabwe, said, “The fall armyworm has further worsened the food security situation of smallholder farmers who are already coping with an ailing economy and climate change. Besides the adverse effects posed to the environment by chemical methods of combating the pest, the smallholder farmer cannot afford to meet the associated costs, hence the need to come up with innovative cost-effective farming systems like climate smart agriculture.”

The fall armyworm, an invasive insect-pest native to the Americas, has caused significant damage to maize crops in sub-Saharan Africa since its arrival to the region in 2016. An integrated approach, including improved agronomic practices, is necessary in order to fight against the invasive caterpillar. However, little is known about the most effective agronomic practices that could control fall armyworm under typical African smallholder conditions. In addition, more information is needed on the impact of fall armyworm on maize yield in Africa, as previous studies have focused on data trials or farmer questionnaires rather than using data from farmer fields. In a new study published by researchers with the International Maize and Wheat Improvement Center (CIMMYT), investigators set out to understand the factors influencing fall armyworm damage and to quantify yield losses due to fall armyworm damage.
The study examined damage in smallholder maize fields in two districts of eastern Zimbabwe. “We estimated the yield losses due to fall armyworm damage at 11.57 percent in the study area. Extrapolated to the whole of Zimbabwe, this would amount to a loss of 200,000 tons of grain, or a value of more than $32 million using the average global price of maize of $163 per ton in 2018,” said Frederic Baudron, cropping systems agronomist at CIMMYT and main author of the study.
Practices such as infrequent weeding or planting on land that had previously been fallow were found to increase fall armyworm damage to maize — most likely because they increased the amount of fall armyworm host plants other than maize. Conversely, practices hypothesized to increase the abundance of natural enemies of fall armyworm — such as minimum and zero tillage or the application of manure and compost — were found to decrease fall armyworm damage. Intercropping with pumpkins was found to increase damage, possibly by offering a shelter to moths or facilitating plant-to-plant migration of the caterpillar. Fall armyworm damage was also higher for some maize varieties over others, pointing to the possibility of selecting for host plant resistance.
“Given the limited coverage of the study in terms of area and season, it would be interesting to replicate it all over the country through the involvement of governmental agricultural departments, so that we get the full picture around the fall armyworm problem at a larger scale,” said Mainassara Zaman-Allah, co-author of the study and abiotic stress phenotyping specialist at CIMMYT.
This study is unique in that it is the first to collect information on agronomic practices that can affect fall armyworm damage using data taken directly from smallholder farmer fields. “Many papers have been written on pest incidence-damage-yield relationships, but with researchers often having control over some of the potential sources of variation,” said Peter Chinwada, TAAT Fall Armyworm Compact Leader at the International Institute of Tropical Agriculture (IITA), another co-author of the study.
“Our study was driven by the desire to determine fall armyworm incidence-damage-yield relationships under typical African smallholder farmer conditions which are characterized by a diversity of cropping systems, planting dates and “pest management practices” that may have been adopted for purposes which have nothing to do with managing pests. Unravelling such relationships therefore requires not only institutional collaboration, but the meeting of minds of scientists from diverse disciplines.”
The results of the study suggest that several practices could be promoted to control fall armyworm in its new home of Africa. “Farmers have already been informed of the results by their extension agents; the NGO GOAL, present in Zimbabwe, shared the findings,” Baudron said. “The next step is to test some of the recommendations suggested in the paper to control fall armyworm such as good weed management, conservation agriculture, use of manure and compost, and stopping pumpkin intercropping. These approaches will need to be refined.”
This work was implemented by the International Maize and Wheat Improvement Center (CIMMYT), GOAL, and the University of Zimbabwe. It was made possible by the generous support of Irish Aid, Bakker Brothers and the CGIAR Research Program on Maize (MAIZE).

On March 14, 2019, over 200 of the International Maize and Wheat Improvement Center’s (CIMMYT) partners in southern Africa, including national research organisations, private seed companies and funders, attended the annual partners field day in Harare, Zimbabwe.
“For the last 34 years, CIMMYT’s regional office has expanded its research work, from maize breeding to sustainable cropping practices and recently appropriate mechanization and post-harvest,’’ said Cames Mguni, Director of Zimbabwe’s Department of Research and Specialist Services. “The development of drought and heat tolerant maize varieties helps farmers get better yields and cope better during drought years such as the current 2018/19 season.”
Elijah Nyabadza, Dean of the University of Zimbabwe’s Faculty of Agriculture, highlighted the strong collaboration between the University and CIMMYT in conducting joint research and building cutting-edge skills of the next generation of agricultural scientists and practitioners in the region.
Welthungerhilfe country director Regina Feindt said the partner field day was ‘’a very valuable experience and a great opportunity to gain technical know-how and exchange with colleagues across the region.’’
CIMMYT showcases research impact
At the event, CIMMYT country representative for Zimbabwe Cosmos Magorokosho walked partners through breeding lines that include special lines testing for resistance to diseases such as fall armyworm, maize streak virus and weevil. Maize breeder Amsal Tarekegne explained how, in product development, various inbred lines are combined to create new hybrids. These new hybrids, added seed systems specialist Peter Setimela, are made available to smallholder farmers for performance testing for stress tolerance and nutritional traits under different environments before being released to seed companies for multiplication.
Two Zimbabwean seed companies present at the field day highlighted the benefits of collaboration with CIMMYT. Chrispen Nyamuda, an agronomist from Zadzamatura seed company, explained that many varieties popular with farmers, which are heat-tolerant and resistant to diseases like maize streak virus and grey leaf spot disease, were developed thanks to their collaboration with CIMMYT. Another partner from Mukushi Seeds described the working partnership with CIMMYT as mutually beneficial. “We exchange lines, plant in different environments and share the results,” he explained. “We are also tapping germplasm from the world through CIMMYT’s global reach.”
Over the last couple of years, CIMMYT has intensified maize breeding efforts aimed at improving the nutritional value of maize, particularly higher content in provitamin A and better quality protein. Maize breeder Thokozile Ndhlela explained that more than 15 new hybrids with higher levels of provitamin A have been released in southern Africa, including five in Zimbabwe.

Agronomists Christian Thierfelder and Isaiah Nyagumbo shared some conservation agriculture techniques adopted by smallholder farmers. Farmers can realize better yields and improve their climate resilience by combining conservation agriculture principles such as minimum soil disturbance, crop rotation and soil cover, with use of stress tolerant maize varieties, appropriate mechanization and other complementary practices. Frederic Baudron, who leads the Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) initiative, explained how small mechanization like two-wheel planters could address labour shortages, reduce drudgery and generate opportunities for rural youth. Significant drudgery reductions have already been observed in wheat planting in Rwanda, and in post-harvest operations like shelling and threshing in Ethiopia and Zimbabwe.

The International Maize Improvement Consortium one year on
Following the annual partners field day, members of the International Maize Improvement Consortium (IMIC) held a field day to select varieties from the IMIC Southern Africa demo plot, which carries a wider selection of materials. Launched in May 2018, IMIC is a public-private partnership initiative established as part of CIMMYT’s mission to increase seed breeding and production innovations.
Participating IMIC members came from seed companies based in Angola, Egypt, Ethiopia, Kenya, Nigeria, Tanzania, Uganda, Zambia and Zimbabwe. At the field day, they were advised by research associate Obert Randi on the layout of the demonstrations for materials under development for different traits, resilience to fall armyworm and maize streak virus, materials improved for vitamin A and quality protein and stress tolerant lines.
After going through the selections, participating IMIC members proceeded to the Quarantine Facility in Mazoe, where they explored around 2,300 double haploid lines undergoing screening maize lethal necrosis (MLN) as well as multiplication for distribution to non-MLN prevalent countries.
The final part of the field day provided space for the members to share research learnings and input on how to move the consortium forward. The field day concluded with an inaugural meeting of the steering committee chaired by CIMMYT regional representative for Africa Stephen Mugo, where participants discussed a number of issues including membership, procedures for conducting field days, training and research prioritization.
Both field days offered an opportunity to highlight the extended impact of CIMMYT’s research in southern Africa through strong partnerships and commitment to research on maize breeding, sustainable farming practices, mechanization and socio-economic impacts of all programming.
The community of the International Maize and Wheat Improvement Center (CIMMYT) joins former colleagues of John A. Mihm, CIMMYT’s maize entomologist during the 1970s-90s, in honoring his memory and valuable work. John passed away on January 25, 2019, at the age of 72.
Special maize populations developed by Mihm and his CIMMYT contemporaries are critical in today’s global quest for new maize varieties to resist the fall armyworm (Spodoptera frugiperda), according to B.M. Prasanna, director of the CIMMYT Global Maize Program and the CGIAR Research Program on Maize.
“The insect-resistant maize germplasm developed by Mihm is proving an invaluable resource in our fight against this pest, underpinning progress in the development of resistant varieties,” said Prasanna.
Crop entomologists were laboriously placing young insect larvae onto plants in greenhouses and in the field until 1976, when Mihm developed the “bazooka.” A plastic tube with a valve that quickly and easily delivered a uniform mixture of corn grits and insect larvae into individual maize plants, the innovation allowed researchers to infest hundreds of plants in a single morning.
Originally from the Americas, fall armyworm has caused major damage to maize crops in Africa since 2016. The pest is now spreading rapidly in Asia, with incidence on maize crops confirmed in India, Bangladesh, Sri Lanka, Myanmar, Thailand, and southern China.
“Without proper controls, fall armyworm could reduce maize grain harvests in Africa alone by an amount worth as much as US$4.6 billion,” Prasanna explained, citing a 2018 report from the Centre for Agriculture and Biosciences International (CABI).
With support from UNDP, Mihm greatly refined CIMMYT practices to rear larvae of maize insect pests and to apply them efficiently so that researchers could identify resistant plants and use them to breed elite, resilient varieties.
After leaving CIMMYT in 1994, Mihm worked for the U.S. company “French Agricultural Research” in studies on sources of resistance in maize to corn rootworm (Diabrotica spp). He eventually retired happily to his farm in Minnesota, according to Florentino Amasende, a former CIMMYT field assistant who was a close friend and colleague of Mihm.
“John was a friend, a mentor and even a father figure for me,” said Amasende, who with support from Mihm for his university studies rose to seed production specialist in leading seed companies. “My family and I are eternally grateful for the opportunities he gave me.”
The importance of maize in Asian cropping systems has grown rapidly in recent years, with several countries registering impressive growth rates in maize production and productivity. However, increasing and competing demands — food, feed, and industry — highlight the continued need to invest in maize research for development in the region. Maize experts from around the world gathered to discuss these challenges and how to solve them at the 13th Asian Maize Conference and Expert Consultation on Maize for Food, Feed, Nutrition and Environmental Security, held from October 8 to 10, 2018, in Ludhiana, Punjab, India.
More than 280 delegates from 20 countries attended the conference. Technical sessions and panel discussions covered diverse topics such as novel tools and strategies for increasing genetic gains, stress-resilient maize, sustainable intensification of maize-based cropping systems, specialty maize, processing and value addition, and nutritionally enriched maize for Asia.
The international conference was jointly organized by the Indian Council of Agricultural Research (ICAR), the International Maize and Wheat Improvement Center (CIMMYT), the Indian Institute of Maize Research (ICAR-IIMR), Punjab Agricultural University (PAU), the CGIAR Research Program on Maize (MAIZE), and the Borlaug Institute for South Asia (BISA).
In Asia, maize is rapidly growing in its importance, due to high demand. Maize productivity in the region is growing by 5.2 percent annually compared to a global average of 3.5 percent. However, this is not enough. “Asia produces nearly 80 million tons of maize annually, but demand will be double by the year 2050,” said Martin Kropff, CIMMYT director general, in his opening address at the conference. “We need to produce two times more maize in Asia, using two times less inputs, including water and nutrients. Climatic extremes and variability, especially in South and South East Asia, will make this challenge more difficult. Continued funding for maize research is crucial. We need to work together to ensure that appropriate innovations reach the smallholder farmers.”

Climate-resilient maize and sustainable intensification
A major theme emphasized at the conference was climate resilience in maize-based systems. South Asia is a hotspot for vulnerability due to climate change and climate variability, which poses great risks to smallholder farmers. “Climate resilience cannot be brought by only a single technology — it has to be through a judicious mix of several approaches,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.
Great advances have been made in developing climate-resilient maize for Asia since the last Asian Maize Conference, held in 2014. Many new heat- and drought-tolerant maize varieties have been developed through various projects, such as the Heat Stress Tolerant Maize for Asia (HTMA), and Affordable, Accessible, Asian (AAA) maize projects. Through the HTMA project, over 50 CIMMYT-derived elite heat-tolerant maize hybrids have been licensed to public and private sector partners in Asia during the last three years, and nine heat-tolerant maize hybrids have been released so far in Bangladesh, India and Nepal.
Sustainable intensification of maize-based farming systems has also helped farmers to increase yields while reducing environmental impact, through conservation agriculture and scale-appropriate mechanization. Simple technologies are now available to reduce harvest time by up to 80 percent and hired labor costs by up to 60 percent. Researchers across the region are also working to strengthen the maize value chains.

Science and appropriate technologies
CIMMYT has been focusing on developing and deploying new technologies that can enhance the efficiency of maize breeding programs; these include doubled haploid (DH) technology, high-throughput field-based phenotyping, and genomics-assisted breeding. The conference emphasized on the need for Asian institutions to adapt such new tools and technologies in maize breeding programs.
Another topic of interest was the fall armyworm, an invasive insect pest that has spread through 44 countries in Africa and was recently reported in India for the first time. “This pest can migrate very quickly and doesn’t require visas and passports like we do. It will travel, and Asian nations need to be prepared,” Prasanna said. “However, there is no need for alarm. We will be looking at lessons learned from other regions and will work together to control this pest.”
In addition to grain for food and feed, specialty maize varieties can provide beneficial economic alternatives for smallholder maize farmers. Conference participants had the opportunity to hear from Indian farmers Kanwal Singh Chauhan and Yugandar Y, who have effectively adopted specialty maize varieties, such as baby corn, sweet corn and popcorn, into life-changing economic opportunities for farming communities. They hope to inspire other farmers in the region to do the same.
On October 10, conference delegates participated in a maize field day organized at the BISA farm in Ladhowal, Ludhiana. Nearly 100 improved maize varieties developed by CIMMYT, ICAR and public and private sector partners were on display, in addition to scale-appropriate mechanization options, decision support tools, and precision nutrient and water management techniques.
The conference concluded with a ceremony honoring the winners of the 2018 MAIZE-Asia Youth Innovators Award. The awards were launched in collaboration between the CGIAR Research Program on Maize and YPARD (Young Professionals for Agricultural Development) to recognize the contributions of innovative young women and men who can inspire fellow youth to get involved in improving maize-based agri-food systems in Asia. Winners of the first edition of the awards include Dinesh Panday of Nepal, Jie Xu of China, Samjhana Khanal of Nepal, and Vignesh Muthusamy of India.

ADDIS ABABA, Ethiopia (CIMMYT) — African farmers have lost millions of dollars in earnings since 2016 due to the loss of crops to the voracious fall armyworm.
Since the initial shock, farmers, researchers, extension officers, agribusinesses, governments and donors have reacted quickly to fight the invasive pest in various ways, including with pesticides, agroecological approaches and new seeds.
Yet the situation is far from under control. A more coordinated research-for-development (R4D) action plan is urgently needed to ensure that effective and affordable solutions reach smallholder farmers in sub-Saharan Africa so they can sustainably combat the devastating pest.
Smallholder farm socioeconomics are highly complex, which makes adoption of any new technology or practice a challenge. “We must look at the big picture to design safer, accessible, effective and sustainable solutions against fall armyworm,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT), which jointly coordinated “Fall Armyworm Research for Development: Status and priorities for Africa,” an international conference held from Oct. 29 to 31 at the African Union Commission in Addis Ababa, Ethiopia.
Hosted by the Fall Armyworm R4D International Consortium, the conference was aimed at drawing a science-based roadmap to combat the hungry caterpillar. The partners organizing the conference were the African Union Commission (AUC), the Alliance for a Green Revolution in Africa (AGRA), the Centre for Agriculture and Biosciences International (CABI), CIMMYT, the Food and Agriculture Organization of the United Nations (FAO), the International Centre of Insect Physiology and Ecology (icipe), the International Institute of Tropical Agriculture (IITA), and the United States Agency for International Development (USAID).
Vulnerable smallholder farmers
African leaders consider the invasive fall armyworm “a big threat for African food security,” said Amira Elfadil, African Union Commissioner for Social Affairs, at the opening of the conference.
The caterpillar has munched through thousands of hectares of maize, sorghum and a few other commercial crops across Africa and is causing severe concerns among food and agriculture experts and policymakers. Since it was first detected in Nigeria and São Tomé, the moth has spread across more than 40 African countries and has been seen in India since July 2018. It could also invade Europe and other continents.
“Fall armyworm has been the fastest pest to expand across the continent,” said Eyasu Abraha, Ethiopia’s state minister for agriculture development.
The pest is a familiar foe to agricultural experts and farmers in the Americas who have fought against it for several decades. However, the pest has found an ideal environment to flourish in Africa, with diverse agro-ecologies and a warmer climate all year round amplifying its persistent threat.
It has a host range of more than 80 plant species, including maize, a staple food on which millions of people throughout sub-Saharan Africa depend for food and income security. It can cause total crop losses, and at advanced larval development stages can be difficult to control even with synthetic pesticides. The female fall armyworm can lay up to a thousand eggs at a time and produce multiple generations very quickly without pause in tropical environments. The moth can fly 100 km (62 miles) a night, and some moth populations have even been reported to fly distances of up to 1,600 kilometers in 30 hours, according to experts.
Entomologists are trying to fill a knowledge gap on how the fall armyworm behaves and migrates throughout Africa.
Solutions that may work to combat the pest in Brazil or North America may not be applicable for the agricultural context in Africa where most farmers are low-resource smallholders, struggling to access new knowledge and technologies.

High cost of ineffective collaboration
Hans Dreyer, director of FAO’s plant protection division, listed many collaborative initiatives, including national task forces and expert working groups, which contributed to document and inform the current state of knowledge.
There are still many knowledge and technical gaps. Some resourceful information platforms are already available for the farmers and extension workers, including the fall armyworm web portal created by CABI, the mobile farmer Q&A service PlantVillage, or Precision Agriculture for Development’s text messaging advisory service MoA-Info.
“The cost of not collaborating is pretty severe,” said Regina Eddy, who leads the Fall Armyworm Task Force at the USAID Bureau for Food Security. The real gamechanger will be that “all experts in the room agree on a common and concrete research-for-development agenda and how to organize ourselves to implement it effectively,” she added.
During the conference, the experts debated intensely on the technical gaps and the best ways to combat the pest through an integrated pest management strategy, including how to scout the caterpillar in the crop field, establish monitoring and surveillance systems, pest control innovations and appropriate policy support to accelerate introduction of relevant innovations.
Safe, sustainable, farmer-centered solutions
Short-term responses to the pest at present include synthetic pesticide use. However, there are public health and environment concerns over some of the toxic pesticides being used in Africa to control the fall armyworm.
Brian Sobel from Catholic Relief Services recalled witnessing a woman in Malawi who, in an effort to combat the pest, sprayed much more chemical pesticide on her maize than necessary.
The rapid increase of the pesticide market in Africa has led to the circulation of plenty of banned or counterfeit products, some very toxic for the farmer, said Steven Haggblade, a professor in the Department of Agricultural, Food and Resource Economics at Michigan State University in the United States. Farmers are often not well trained in the use of such chemicals and do not protect themselves during application, he said.
Pesticide use has many negative trade-offs, said Paul Jepson, a professor of environmental and molecular toxicology in the College of Agricultural Sciences at Oregon State University. Natural enemies like parasitic wasps are also often far more vulnerable to pesticides than fall armyworm larvae, which are hard to reach and hide themselves in the maize whorls for instance.
Continental action plan
A key recommendation made by the Fall Armyworm R4D International Consortium is to develop common methodologies and research protocols to ensure data from various studies across the continent are better used and compared. For example, how best could the true impacts of the fall armyworm on food and seed security, public health and environment be measured? Collaborative research could include multilocation assessment of the relationship between observed crop damages and yield losses, which is key to determine the efficacy of a pest control innovation.
Conference participants also agreed to work on defining economic and action thresholds for fall armyworm interventions, to ensure better recommendations to the farming communities.
Because no one solution can fit all farmers and socioeconomic contexts, advice must include use of environmentally safer pesticides, low-cost agronomic practices and landscape management and fall armyworm-resistant varieties, among other integrated pest management tools.
Enhanced cooperation between countries to access new technologies and manage the transboundary pest is seen as a priority. Consortium experts also urge an integrated pest management approach, initiated based on farmers’ needs. Controlling the fall armyworm in the long run will require important investments into research-for-development for generating and sharing knowledge and addressing technical gaps with farmers.

DES MOINES (Iowa) — At the plenary of the 2018 Borlaug Dialogue, a global panel of experts gave an overview of the origins of the fall armyworm, how it is spreading around the world, and how governments, farmers and researchers are fighting against this pest.
Pedro Sanchez, research professor in tropical soils at the University of Florida and 2002 World Food Prize Laureate, shared background information on the history of the fall armyworm and the early attempts to neutralize it, decades ago. He pointed out that once-resistant varieties were eventually affected by this pest.
The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, shared the most recent developments and explained how organizations are working together to respond to this pest. “We want to have science-based, evidence-based solutions,” Kropff said. “We have to solve the problem based on science, and then to develop and validate and deploy integrated pest management technologies.”
The director general of the Ethiopian Institute of Agriculture, Mandefro Nigussie, reminded that in addition to affecting people and the environment, fall armyworm “is also affecting the future generation,” as children were pulled out of school to pick larvae.
The response against fall armyworm cannot be done by governments alone, panelists agreed. It requires the support of multiple actors: financing the research, producing research, promoting the results of the research and implementing appropriate measures.
Rob Bertram, chief scientist at USAID’s Bureau for Food Security predicted the fall armyworm will continue to be a “serious problem” as it moves and migrates.
The director general and CEO of the Kenya Agricultural & Livestock Research Organization, Eluid Kireger, emphasized the importance of global collaboration. “We need to borrow the technologies that are already working”.
The fall armyworm was also discussed during the Corteva Agriscience Forum side event, on a session on “Crop security for food security”. The Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize, B.M. Prasanna, was optimistic about the efforts to tackle this voracious pest. “I’m 100 percent confident that the pest will be overcome, but it requires very solid synergistic and coordinated actions at the national level, at the regional level and at the continental level.”
CIMMYT is co-leading the Fall Armyworm R4D International Consortium. “Fall armyworm is not going to be the only threat now and forever; there will be more insects, pests and pathogens moving around,” Prasanna said. “Global connectedness is exacerbating this kind of problem, but the solution lies also in global connectedness.”
B.M. Prasanna and I joined colleagues at the 13th Asian Maize Conference and stressed the need for continued funding for maize research, keeping in mind climate change and the challenge of the insatiable fall armyworm, which spread to India this year.
NAIROBI (Kenya) — As the invasion of the voracious fall armyworm threatens to cause US$3-6 billion in annual damage to maize and other African food staples, 35 organizations announced today the formation of a global coalition of research for development (R4D) partners, focused on developing technical solutions and a shared vision of how farmers should fight against this pest. After causing extensive crop damage in Africa, the presence of the fall armyworm was recently confirmed in India.
The new Fall Armyworm R4D International Consortium will serve to develop and implement a unified plan to fight this plant pest on the ground. Focusing on applied research, the consortium joins other global efforts and coordinates with international bodies working against this pest. The Fall Armyworm R4D International Consortium will be co-led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA).
“This pest caught us all by surprise and it continues eating away at maize and other crops that are important for the food security and livelihoods of African farmers. We can no longer afford to work in isolation,” said the Director General of CIMMYT, Martin Kropff. “Many organizations in the public and private sector are working intensively on different approaches,” he added, “but farmers are not interested in half solutions. They want to have integrated solutions, supported by strong science, which work effectively and sustainably.”
Consortium members will coordinate efforts to pursue a wide range of options for fighting fall armyworm, with a strong emphasis on integrated pest management, which includes host plant resistance, environmentally safer chemical pesticides, biological and cultural control methods, and agronomic management.
The Deputy Director General for Partnerships for Delivery at IITA, Kenton Dashiell, said that efforts are underway to identify and validate biopesticides, or “very safe products that don’t harm the environment or people but kill the pest.” In some areas, Dashiell explained, farmers may need to consider temporarily switching to a food crop that is not susceptible to armyworm.

The Vice President of Program Development and Innovation at the Alliance for a Green Revolution in Africa (AGRA), Joe DeVries, said his organization is serving as a bridge between scientists and farmers. AGRA is developing a network of “village-based advisers” across 15 countries who will be connected to farmers via a “private sector-led” extension system to help farmers deal with fall armyworm infestations. AGRA and its partners already have trained more than 1,000 advisers and expect to add several thousand more who can “quickly bring to farmers the latest knowledge about the best methods of control.”
The Chief Scientist at the Bureau of Food Security of the United States Agency for International Development (USAID), Rob Bertram, expressed his excitement about the formation of the consortium, both for its immediate relevance for fighting fall armyworm and as a forerunner of “more resilient” agriculture systems in Africa, which is likely to see similar threats in the future. CIMMYT and USAID, together with global experts, developed an integrated pest management guide to fight fall armyworm, available in English, French and Portuguese.
The Director General of Development at the Center for Agriculture and Biosciences (CABI), Dennis Rangi, noted that the ability for people to more rapidly travel around the world is also making it easier for plant pests to hop from continent to continent. “Today we are focusing on the fall armyworm, tomorrow it could be something different,” he said.
The members of the Fall Armyworm R4D International Consortium will hold their first face-to-face meeting on October 29-31, 2018, in Addis Ababa, Ethiopia. This international conference will be organized by CIMMYT, IITA, AGRA, CABI, FAO, icipe, FAO, USAID and the African Union Commission.
The technical coordinators of the consortium are B.M. Prasanna, Director of the CGIAR Research Program MAIZE and Global Maize Program at CIMMYT, and May-Guri Saethre, Deputy Director General of Research for Development at IITA.

A new 3-D animation video published yesterday shows farmers how to scout for and identify the fall armyworm (Spodoptera frugiperda).
The video shows scouting techniques and highlights the importance of identifying any pest damage at the early stages of crop growth. If the fall armyworm is present, integrated pest management practices can help farmers protect against this pest.
Farmers should avoid applying an indiscriminate amount of chemical pesticides, as that will lead to the fall armyworm building resistance to pesticides. It may also cause harm to people and to the environment.
The video was produced by Scientific Animations Without Borders (SAWBO), funded by USAID and developed by the International Maize and Wheat Improvement Center (CIMMYT), the International Institute of Tropical Agriculture (IITA) and Michigan State University.

The fall armyworm (FAW), Spodoptera frugiperda, a devastating insect-pest, has been identified for the first time on the Indian subcontinent. Native to the Americas, the pest is known to eat over 80 plant species, with a particular preference for maize, a main staple crop around the world. The fall armyworm was first officially reported in Nigeria in West Africa in 2016, and rapidly spread across 44 countries in sub-Saharan Africa. Sightings of damage to maize crops in India due to fall armyworm mark the first report of the pest in Asia.
Scientists from the College of Agriculture at the University of Agricultural and Horticultural Sciences (UAHS) confirmed the arrival of the pest in maize fields within campus grounds in Shivamogga, in the state of Karnataka, southern India. Both morphological and molecular techniques confirmed the identity as FAW.
A pest alert published on July 30 by the National Bureau of Agricultural Insect Resources (NBAIR), part of the Indian Council of Agricultural Research (ICAR), further confirmed a greater than 70% prevalence of fall armyworm in a maize field in the district of Chikkaballapur, in the state of Karnataka. Unofficial reports of incidence of FAW are rapidly emerging from several states in India, including Andhra Pradesh, Maharashtra and Telangana.
The pest has the potential to spread quickly not only within India, but also to other neighboring countries in Asia, owing to suitable climatic conditions.

“The strategies outlined in this manual can be of great importance to farmers in India when dealing with this insect pest. FAW is indeed one of the most destructive crop pests, and there is no option than to adopt an integrated pest management strategy to effectively tackle this complex challenge,” said B.M. Prasanna, director of MAIZE and the Global Maize Program at CIMMYT. “MAIZE and partners are dedicated to finding solutions to this problem that will protect the food security and incomes of smallholder farmers across Asia and Africa.”
Other regions are at risk as well. Researchers have warned of the potential impacts if FAW spreads to Europe, where customs inspectors have already reported having discovered and destroyed the pest on quarantined crops imported from Africa on several occasions.
Global experts on maize and key stakeholders in Asia will gather together in Ludhiana, India, on October 8-10, 2018, for the 13th Asian Maize Conference to discuss pressing issues to the crop across the continent, including the spread of fall armyworm. The conference, organized by the Indian Council of Agricultural Research (ICAR), the Indian Institute of Maize Research (IIMR), CIMMYT, MAIZE, Punjab Agricultural University (PAU) and the Borlaug Institute for South Asia (BISA), is expected to attract more than 250 participants from almost all the major maize-growing countries in Asia.
Nairobi, Kenya (CIMMYT) – A new comprehensive integrated pest management (IPM)-based technical guide produced by international experts will help scientists, extension agents and farmers to tackle the fall armyworm (Spodoptera frugiperda), which has rapidly spread across the African continent in the last two years, decimating maize crops in its path.
Native to North America, the fall armyworm has recently emerged as a major threat in Africa, where it has been identified in over 30 countries since it was first confirmed on the continent in January 2016. The pest can potentially feed on 80 different crop species but has a preference for maize, which poses a significant threat to the food security, income and livelihoods of over 300 million African smallholder farm families that consume maize as a staple crop.
“The potential impact of the fall armyworm as a major food security and economic risk for African nations cannot be overstated,” said Martin Kropff, director general at CIMMYT.
If proper control measures are not implemented, the fall armyworm could cause extensive maize yield losses of up to $6.2 billion per year in just 12 countries in Africa where its presence has been confirmed, according to the Centre for Agriculture and Biosciences International (CABI).
“The fall armyworm poses an enormous and wide-scale risk to the livelihoods of several million African smallholders, and requires urgent deployment of an IPM strategy and quick response from all stakeholders,” said B.M. Prasanna, director of MAIZE and the Global Maize Program at CIMMYT. “The Fall Armyworm Integrated Pest Management Guide provides comprehensive details on the best management practices to help smallholder farmers effectively and safely control the pest while simultaneously protecting people, animals and the environment.”
