CGIAR’s Plant Health Initiative (PHI) is testing integrated pest management (IPM) packages against fall armyworm (FAW) in partnership with smallholder farmers and agricultural extension officers at the Plant Health Innovation Platform at the Kenya Agricultural and Livestock Research Organization (KALRO) Kiboko Research Station in Kenya.
The IPM packages comprise 18 combinations of treatments, including maize varieties with native genetic resistance to FAW, biopesticides, biological control agents, push-pull system, and bean varieties.
“This is a unique opportunity to identify eco-friendly and cost-effective IPM packages against a major pest like FAW through participatory engagement of smallholder farmers and extension personnel,” said BM Prasanna, Global Maize Program Director at the International Maize and Wheat Improvement Center (CIMMYT) and CGIAR Plant Health Initiative Lead. “Also In our efforts against FAW, three FAW-tolerant maize hybrids have been recommended for release after national performance trials in Kenya.”

Participatory assessment
Participating farmers and extension personnel made their first assessment of the IPM combinations at the vegetative stage on November 8, 2022.
“With this second assessment on February 7, 2023, farmers and extension personnel are evaluating the same IPM combinations for their yield potential, which means the plants need to be not only healthy but also productive. The farmers are also looking at the quality of the maize ears, and the level of ear and kernel damage by the pest, if any. These assessments both at the vegetative and reproductive stages are critical for us to conclude this experiment and draw appropriate inferences,” Prasanna said.
Researchers will analyze the efficacy of the scoring of different IPM treatments by the farmers and from the vegetative/foliar and reproductive/harvest stages. In addition, scientists will conduct a cost-benefit analysis for each IPM treatment to identify relevant IPM packages that can be potentially scaled. Prasanna noted the initial scoring by the scientists and farmers were highly comparable.
The trials engaged farmers and extension workers from five different counties in Kenya. “The Plant Health Initiative is keen on co-creation and co-validation and taking an inclusive, participatory approach to innovations,” said Prasanna. He added that such an approach is vital for buy-in by the farmers, who need to be active partners in effectively scaling the selected IPM packages.
Farmers participating in the Field Day at the Innovation Platform applauded the initiative to involve them in validating solutions to manage FAW and expressed their eagerness to have the innovations in their hands. The farmers also had opportunities to ask questions, provide preliminary verbal feedback, and receive immediate clarification from the scientists to their queries.
”I know a farmer who has trained his two sons to go to every plant and kill the armyworm physically. You can imagine the time and energy that takes,” said Justice Kimeu, a farmer from Makueni County, Kenya. “Let the innovative methods we have seen here reach every farmer across the country.”

Plant Health Innovation Platform catalyzes collaboration
The Plant Health Innovation Platform at Kiboko brings together different innovations developed by the collaborating institutions: CIMMYT, KALRO, International Center for Insect Physiology and Ecology (icipe), AgBiTECH, Center for Agriculture and Bioscience International (CABI), and Farmfix Africa.
“Robust data is being generated on the efficacy and cost-benefit of various IPM combinations. After data analysis, 2-3 few specific IPM packages will be identified based on efficacy against FAW, cost effectiveness, affordability to smallholder farmers, and potential for rapid scale up,” Prasanna said.
Besides the FAW Innovation Platform at Kiboko, Kenya, the CGIAR Plant Health Initiative is operating eight other Innovation Platforms in Benin, Cameroon, Nigeria, Uganda, Lebanon, Philippines, Ecuador, and Colombia. Each of these platforms bring together diverse institutions engaged in developing game-changing solutions in managing key pests and diseases in the Initiative’s primary crops that include maize, banana, cassava, potato, sweet potato, rice, yam, sorghum, wheat, millets, legumes, and vegetables.
Since the outbreak of FAW was reported in 2016, maize yields have dropped by between 30-50 percent, increasing the country’s challenges for food security.
Prasanna Boddupalli, Director of the Global Maize Program at CIMMYT, said, ″We want farmers to dissociate from application of synthetic toxic pesticides and chemicals but revert to use of combined approaches like use of resistant varieties, bio-pesticides and related biological control methods that are environmentally friendly.”
Preliminary assessment of the viability of naturally tolerant maize varieties from Mexico suggests that at least two or three resistant varieties may be approved after certification from the regulator.

CGIAR together with national, regional, and international partners kicked off the Plant Health and Rapid Response to Protect Food Security and Livelihoods Initiative also known as the Plant Health Initiative in Nairobi, Kenya, on May 12-13, 2022. The Initiative’s inception meeting was fittingly held on the first-ever International Day of Plant Health on May 12 and was attended by over 200 participants (both in-person and virtual), representing diverse institutions.
The Plant Health Initiative targets a broad range of pests and diseases affecting cereals (especially rice, wheat and maize) and legumes such as beans, faba bean, chickpea, lentil, and groundnut; potato; sweet potato; cassava; banana; and other vegetables.
Speaking at the meeting, CGIAR Plant Health Initiative Lead and Director of Global Maize Program at the International Maize and Wheat Improvement Center (CIMMYT) noted that climate change, together with human activities and market globalization, is aggravating challenges to plant health, including outbreaks of devastating insect-pests and diseases. In addition, according to data from the African Union Partnership on Aflatoxin Control in Africa (AUC-PACA), 40 percent of commodities in local African markets exceed allowable levels of mycotoxins in food, causing adverse effects on diverse sectors, including agriculture, human health, and international trade.
“The CGIAR Plant Health Initiative is, therefore, a timely program for strengthening inter-institutional linkages for effective plant health management especially in the low- and middle-income countries in Africa, Asia, and Latin America, said Prasanna. “This calls for synergizing multi-stakeholder efforts to improve diagnostics, monitoring and surveillance, prediction and risk assessment of transboundary pests and pathogens, and implementing integrated pest and disease management in a gender-responsive and socially inclusive manner.”
Demand-driven multistakeholder approach
CGIAR Global Science Director for Resilient Agrifood Systems Martin Kropff reiterated the importance of the Initiative, and emphasized the need for a global plant health research-for-development consortium. He mentioned that all the CGIAR Initiatives, including the Plant Health Initiative, are demand-driven and will work closely with national, regional, and international partners for co-developing and deploying innovative solutions.
The chief guest at the event, Oscar Magenya, Secretary of Research and Innovation at Kenya’s Ministry of Agriculture, pointed out the need for a well-coordinated, multisectoral and multistakeholder approach to managing invasive pests and diseases. He recognized CGIAR’s contribution and partnership with the Government of Kenya through CIMMYT, especially in combating maize lethal necrosis and wheat rust in Kenya.
“As government, we invite the CGIAR Plant Health Initiative to partner with us in implementing the Migratory and Invasive Pests and Weeds Management Strategy that was launched recently [by the Kenya Government],” said Magenya.
Implications of Plant Health in Africa and globally
Zachary Kinuya, Director of Crop Health Program at the Kenya Agricultural and Livestock Research Organisation (KALRO) spoke on the importance of plant health management to African stakeholders, and observed that in addition to improved crop production, food and feed safety must be given adequate priority in Africa.
Director of the Plant Production and Protection Division at the UN Food and Agriculture Organization (FAO), Jingyuan Xia applauded CGIAR for launching the global Initiative. Through his virtual message, Xia stated that the goals of the two organizations are aligned towards supporting farmers and policy makers in making informed decisions and ultimately ending global hunger. He added that the CGIAR has strong research capacity in developing and disseminating new technologies.
CIMMYT Director General Bram Govaerts explained how negative impacts on plant health, combined with climate change effects, can lead to global production losses and food system shocks, including the potential to result in food riots and humanitarian crises. He challenged stakeholders in the meeting to resolve tomorrow’s problems today, through collective and decisive action at all levels.

The German development agency (GIZ) Fund International Agricultural Research (FIA) Advisor Sarah Schmidt said that GIZ supports the Initiative because of its interest in transformative approaches in innovations for sustainable pest and disease management. Recognizing women’s major involvement in farming in Africa, Schmidt said there is a need to empower and equip women with knowledge on plant health as this will result to greater productivity on farms in Africa. “We welcome that the Plant Health Initiative dedicated an entire crosscutting work package to equitable and inclusive scaling of innovations,” she added.
Participants at the launch were also reminded by Ravi Khetarpal, Executive Secretary of the Asia-Pacific Association of Agricultural Research Institutions (APAARI), that the Initiative is now at the critical phase of Implementation and requires diverse actors to tackle different issues in different geographies. Ravi added that biosecurity and plant health are important subjects for the Asia-Pacific region, in view of the emergence of new pests and diseases, and therefore the need to save the region from destructive pest incursions.
Other online speakers at the launch included Harold Roy Macauley, Director General of AfricaRice & CGIAR Regional Director, Eastern and Southern Africa; Nteranya Sanginga, Director General of the International Institute of Tropical Agriculture (IITA) and CGIAR Regional Director, West and Central Africa; and Joaquin Lozano, CGIAR Regional Director, Latin America & the Caribbean.
Reflecting on gender, social inclusion, and plant health
Panel discussions allowed for more in-depth discussion and recommendations for the Initiative to take forward. The panelists delved into the progress and challenges of managing plant health in the Global South, recommending a shift from a reactive to a more proactive approach, with strong public-private partnerships for sustainable outcomes and impacts.
Gender inequities in accessing the plant health innovations were also discussed. The discussion highlighted the need for participatory engagement of women and youth in developing, validating and deploying plant health innovations, a shift in attitudes and policies related to gender in agriculture, and recognition and deliberate actions for gender mainstreaming and social inclusion for attaining the Sustainable Development Goals (SDGs).

For a decade, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been at the forefront of a multidisciplinary and multi-institutional effort to contain and effectively manage maize lethal necrosis (MLN) disease in Africa.
The manual is relevant to stakeholders in countries where MLN is already present, and also aims to offer technical tips to “‘high-risk’ countries globally for proactive implementation of practices that can possibly prevent the incursion and spread of the disease,” writes B.M. Prasanna, director of CIMMYT’s Global Maize Program and MAIZE, in the foreword.
“While intensive multi-disciplinary and multi-institutional efforts over the past decade have helped in containing the spread and impact of MLN in sub-Saharan Africa, we cannot afford to be complacent. We need to continue our efforts to safeguard crops like maize from devastating diseases and insect-pests, and to protect the food security and livelihoods of millions of smallholders,” says Prasanna, who is presently leading the OneCGIAR Plant Health Initiative Design Team.
Fall armyworm continues to cause havoc in Africa. Farmers in Somalia have not been spared since this unwelcome guest showed up in the country over three years ago. As part of the mitigation measures, the Somali Agriculture Technical Group (SATG) in partnership with the International Maize and Wheat Improvement Center (CIMMYT) and the International Committee of the Red Cross (ICRC) recently conducted online trainings on fall armyworm management for sustainable crop protection. The online trainings, targeting national agriculture stakeholders in the country, took place on August 25 and September 30, 2020, with nearly 250 participants attending both webinars.
“This is the first of our efforts to reach out to our partners in Somalia, especially the Somali Agriculture Technical Group and the national agricultural research system, to increase the awareness on the integrated pest management approaches that can help combat this highly destructive pest,” said B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize (MAIZE).
“This training was designed to help participants to gain a better understanding about fall armyworm, how to identify it, how to monitor and scout for it, how to effectively implement a management strategy that is environmentally and ecologically benign, in order to protect the food security and livelihoods of farmers and their families,” Prasanna said.
An integrated pest management strategy for sustainable control of fall armyworm should consider various interventions, including regular scouting and monitoring of the pest in the fields, host plant resistance, biological and biorational control, agroecological management, and use of environmentally safer pesticides and good agronomic practices tailored for the socio-cultural and economic contexts of the farmers. Ultimately, the purpose of a functional integrated pest management approach is to suppress pest population by applying techniques that minimize human and environmental harm, while protecting the crops from economic damage.
“I am happy to see the expertise from high levels of research at CIMMYT, icipe, IITA, universities, SATG and the humanitarian sector coming together to tackle and solve problems linked to food production and consumption. I believe that such important trainings have great value for Somalia, and should be further strengthened and encouraged,” said Abdalla Togola from the ICRC.

Hussein Haji, the Executive Director of SATG was optimistic that the training would go a long way to empower farmers in Somalia, through their cooperatives, and could lead to better ways of tackling challenges such as fall armyworm, already made worse by other stresses like drought and desert locusts.
“Through our extension workers, we hope this information will trickle down to our cooperatives, who produce mainly maize and sorghum seed in Somalia,” he added.
This comes on the back of a partnership between the ICRC and SATG to implement activities intended to improve food production among rural communities in six regions of Somalia. The partnership would enhance quality seed production with a focus on maize and sorghum, the major staple crops in the country.
Besides Prasanna, the key resource persons included Dan McGrath (Professor Emeritus, Oregon State University, USA), Joseph Huesing (CIMMYT Consultant on integrated pest management) and Georg Goergen (Entomologist, International Institute of Tropical Agriculture), Frederic Baudron (CIMMYT Systems Agronomist), Anani Bruce (CIMMYT Entomologist), Yoseph Beyene (CIMMYT Regional Breeding Coordinator for Africa) and Saliou Niassy (Head of Agricultural Technology Transfer Unit, International Center of Insect Physiology and Ecology).
The fall armyworm, a voracious caterpillar officially reported for the first time in Africa in Nigeria in 2016, remains a serious pest with devastating consequences on millions of farmers’ food and livelihood security. The pest has spread quickly throughout sub-Saharan Africa, primarily attacking maize and sorghum, two main staple crops in the region. The Food and Agriculture Organization of the United Nations (FAO) estimates up to 18 million tons of maize are lost to the pest annually, at an estimated economic loss of $4.6 billion.
To reduce the losses, experts have been recommending a toolbox of integrated pest management (IPM) practices to minimize the damage on smallholder farmers’ fields. Scientists at CIMMYT are also working intensively to develop improved maize varieties with native genetic resistance to this devastating insect pest.

The fall armyworm (Spodoptera frugiperda; FAW), an insect-pest native to the Americas, has been a persistent and serious pest of maize for over a century. Public and private sector scientists in the Americas – particularly in Brazil and the United States – have developed and deployed effective strategies to control the pest.
Incidence of fall armyworm was first reported in Nigeria in January 2016, and subsequently in over 40 countries across Africa. In Asia, the pest was first reported in India in mid-2018, and has since emerged in several countries in the Asia-Pacific. Strategies for fall armyworm management in both Africa and the Asia-Pacific can benefit immensely from those already fine-tuned in the Americas, with necessary customization to fit local agroecologies and farming systems. There is also a need to intensively work on various aspects of integrated pest management (IPM) for effective and sustainable fall armyworm management. This includes Research-for-Development (R4D) for discovering, validating and piloting best-bet technological interventions or management practices.
This project brings together the expertise of key institutions with long-standing experience in effectively dealing with transboundary insect-pests to strengthen the capacities of Africa- and Asia-based institutions in fall armyworm management. The goal is to develop and disseminate comprehensive, expert approved, IPM-based fall armyworm pest management practices that will enable various stakeholders – especially farmers, extension agents, and pest control advisors – to effectively scout, determine the need for, and appropriately apply specific interventions to control the fall armyworm in maize and other crops in Africa and Asia.
Objectives
Develop, publish and disseminate comprehensive, expert-approved, IPM-based information resources for various stakeholder groups
Integrate traits for fall armyworm resistance into the CIMMYT breeding pipeline
Establish a fall armyworm Research-for-Development (R4D) Consortium
Fall armyworm, a voracious pest now present in both Africa and Asia, has been predicted to cause up to $13 billion per year in crop losses in sub-Saharan Africa, threatening the livelihoods of millions of farmers throughout the region.
“In their haste to limit the damage caused by the pest, governments in affected regions may promote indiscriminate use of chemical pesticides,” say the authors of a recent study on fall armyworm management. “Aside from human health and environmental risks,” they explain, “these could undermine smallholder pest management strategies that depend largely on natural enemies.”
Agro-ecological approaches offer culturally appropriate, low-cost pest control strategies that can be easily integrated into existing efforts to improve smallholder incomes and resilience through sustainable intensification. Researchers suggest these should be promoted as a core component of integrated pest management programs in combination with crop breeding for pest resistance, classical biological control and selective use of safe pesticides.
However, the suitability of agro-ecological measures for reducing fall armyworm densities and impact must be carefully assessed across varied environmental and socioeconomic conditions before they can be proposed for wide-scale implementation.
To support this process, researchers at the International Maize and Wheat Improvement Center (CIMMYT) reviewed evidence for the efficacy of potential agro-ecological measures for controlling fall armyworm and other pests, consider the associated risks and draw attention to critical knowledge gaps. Findings from the Africa-wide study indicate that several measures can be adopted immediately, such as sustainable soil management, intercropping with appropriately selected companion plants and the diversification of farm environments through management of habitats at multiple spatial scales.
