Fighting the stress

East African Seed Company has a rich history of nearly 50 years, serving farmers with improved climate-resilient seed varieties. Established in 1972, the company produces and sells improved seed, through a wide distribution network in at least 15 countries in sub-Saharan Africa. It also markets agrochemicals and other farm inputs, and has ambitions of expanding to the rest of Africa, trading as Agriscope Africa Limited.

Smallholder farmers in sub-Saharan Africa continue to face multiple biotic and abiotic stresses as they try to improve their farms’ productivity and their livelihoods. Maize seed that guarantees high yield is a key trait, coupled with other key attributes such as drought tolerance, disease and pest resistance, early seedling vigor as well as suitability for food and animal feed.

With the varieties serving both small- and large-scale commercial farmers, challenges such as the fall armyworm, diminishing soil fertility and erratic rains have persisted in recent years and remain as key farming obstacles. “Such challenges diminish crop production and the grain quality thereby, lessening farmers’ profitability,” says Rogers Mugambi, Chief Operating Officer of East African Seed Company.

Scientists at the International Maize and Wheat Improvement Center (CIMMYT), in collaboration with partners in the national agriculture research systems and the commercial seed sector, continue to develop seed varieties that can guarantee decent yield even in times of climatic, disease and pest stress.

Top-notch research trickles down to farmers

Over the years, East African Seed has inked partnerships with CIMMYT, national research institutes and other agencies in the countries where it operates. Such partnerships have been the driving force to its success and the impacts within the farming communities in sub-Saharan Africa.

“Our collaboration with CIMMYT began in 2008 with germplasm acquisition. The cooperation has expanded to include testing networks for new hybrids, early-generation seed production and marketing. The overall beneficiary is the smallholder farmer who can access quality seeds and produce more with climate-smart products,” Mugambi says.

Apart from the multi-stress-tolerant varieties developed and released over time by the national agricultural research programs, CIMMYT recently announced a breakthrough: fall armyworm-tolerant elite maize hybrids for eastern and southern Africa. This success followed three years of rigorous research and experiments conducted in Kenya and signified a key milestone in the fight against fall armyworm.

As part of the partnership in the Drought Tolerant Maize for Africa (DTMA) and Stress Tolerant Maize for Africa (STMA) projects, East African Seed Company (Agriscope Africa Limited) established demonstration farms and conducted field days in Kenya, reaching thousands of farmers as a result. It was also able to produce early generation seed, which supported production of 2,000 metric tons of certified seed. This partnership now continues in the Accelerating Genetic Gains in Maize and Wheat (AGG) project.

The company has contracted large- and small-scale growers across the country to meet its seed production targets.

“Most of our small-scale growers are clustered in groups of up to 30 farmers with less than five acres of farmland. The large growers have advanced irrigation facilities such as the pivot system and seed processing plants. The seed from the fields is pre-cleaned and dried in the out-grower facilities before delivery to our factory for further cleaning and processing,” Mugambi explains.

Out with the drought

Currently, of the 1,300 metric tons of drought-tolerant hybrid seeds it produces yearly, 500 metric tons constitute those derived from the partnership in the STMA project. Two notable hybrids, HODARI (MH501) and TOSHEKA (MH401), were derived during the DTMA and STMA projects. Released in 2014 and accepted for regional certification through the Common Market for Eastern and Southern Africa (COMESA)’s regional catalogue, the MH501 is a mid-altitude adapted and medium maturing three-way cross hybrid. The yield advantage of 15% over the local commercial checks triggered widespread adoption by the farmers, according to Mugambi. In Kenya, it was used as a commercial check during national performance trials, from 2017 to 2019.

The MH401, an early maturing hybrid with moderate drought tolerance, has been adopted in lowland and mid-altitude dry ecologies of Kenya and Tanzania. It has a 20% yield advantage over the local commercial checks.

As part of its varietal replacement, East African Seed Company looks to steadily retire older varieties such as KH600-15A and WE1101 and promote new ones including TAJIRI (EASH1220), TAJI (MH502) and FARAJA (MH503).

To promote new varieties and successfully reach smallholders, the company conducts field days, farm-level varietal demonstrations, road shows and radio programs. It also disseminates information on the benefits of new varieties while also dispensing promotional materials such as branded t-shirts and caps.

“Additionally, we organize annual field days at our research farm in Thika, where key and influential farmers and other stakeholders are invited from across Kenya and neighboring countries to learn about our new agricultural technologies,” Mugambi says.

Spraying locusts before they can fly key for effective control

Written by Alison Doody on February 27, 2020. Posted in News. 2 Comments on Spraying locusts before they can fly key for effective control

East African countries are battling the worst desert locust invasion in decades. The locusts are devouring crops and pasture leaving in their wake a region that is staring at a potential food crisis. The swarms have swept across Djibouti, Eritrea, Ethiopia, Kenya, South Sudan, Somalia, Sudan, Tanzania and Uganda, with some of these countries reporting the worst outbreak in 70 years.

Experts have warned of a second round of the flare-up, as the eggs laid along the locust path hatch. Both aerial and ground spraying with insecticides continue but such interventions have not yielded much success.

Stephen Njoka, Director of the Desert Locust Control Organization for Eastern Africa (DLCO-EA) and Hugo De Groote, Agricultural Economist at the International Maize and Wheat Improvement Center (CIMMYT) share some insights on the outbreak, effective control measures and what can be done to mitigate the damage currently and in potential future outbreaks.

Q: What is your opinion on the locust invasion across the eastern Africa region?

A: The current locust invasion in the eastern Africa region is one of the most serious occurrences in decades. For Ethiopia and Kenya, this is the worst outbreak in over 25 years and 70 years respectively. The locusts have caused significant damage in pastoral regions, where they have devoured pasture and tree leaves. They are now reaching some of the major maize growing areas where they are likely to cause a lot of damage to the crops.

Q: Why are they called desert locusts?

A: They breed in the wet desert sands. In west Africa for instance, they would breed in the border areas between the Sahel and the Sahara Desert. They go through six stages; five of which are the non-flying phases. Once they reach adult stage, they start flying, mating and laying eggs, and the cycle continues.

They are usually solitary in nature, but occasionally move into their gregarious state, in which they alter their behavior and physical appearance, form swarms and migrate over long distances following the winds. This is what differentiates locusts from grasshoppers. When they land at a particular location, they cause a lot of damage in that specific area. Apart from that local destruction, however, they may not cause much harm on a national scale.

Q: How serious of a problem is this invasion to the food security status of countries like South Sudan that are just recovering from decades of conflict and a recent drought?

A: The invasion could pose a serious food security challenge in some areas as these insects consume their own weight in a day (one insect weighs 2 grams and a swarm can contain over 50 million insects).

For countries like South Sudan and Somalia where conflicts can hamper locust control efforts, the food insecurity situation gets compounded. Pastures are the worst hit as locusts tend to prefer hotter climates where livestock keeping is the main source of livelihood.

Q: In your experience, what is the best way to deal with such an invasion? What are the most effective control measures?

A: The best way to deal with such an invasion is to conduct aerial spraying using Ultra Low Volume (ULV) chemical or biological pesticides at the early stages for effective control. It is important to identify the egg-laying sites early on so that the emerging hoppers are sprayed before they can fly.

Q: We understand that this is the worst invasion in Kenya in about 70 years and the worst in 25 years in some neighboring countries such as Ethiopia. Should we expect another infestation a few years from now?

A: It is unlikely that we can expect another invasion of this magnitude in the near future. The current invasion may have been driven by climatic changes in the breeding areas of the Red Sea coast, war-torn Yemen and Somalia.

Q: How can we be better prepared given that such invasions are cyclical in nature and may happen again after some years or decades?

A: Continued monitoring and forecasting of the locust population in the traditional breeding sites should be a priority. Countries in the invasion areas should establish Locust Control Units under the appropriate ministries. These units should frequently get updates from the FAO Desert Locust Information Service (DLIS) in Rome and take precautionary steps as advised.

As the eastern Africa region, member countries of DLCO-EA should step up their support for the organization by acquiring modern aircrafts, which can conduct aerial spraying more effectively and efficiently.

Q: What monitoring measures are in place for the surveillance and recommended remedial measures, especially in periods of low densities just before they become gregarious? Who does the monitoring and how frequently is the monitoring done?

A: Locust scouting teams in the breeding areas are charged with monitoring and surveillance of these pests. The exercise is continuous and largely supported by FAO DLIS using appropriate equipment like elOCUST 3, a data recording and transmission system for crop pest monitoring, currently used as a detection and early warning tool for desert locusts.

Q: Are mitigation measures such as compensation for affected farmers an option?

A: Where farmers are seriously hit, government, intergovernmental agencies or non-governmental organizations may consider easing the farmers’ losses by offering food and/or financial support.

Q: We have seen efforts such as aerial or ground spraying of the pests. How effective are these interventions? What implications does this control measure have on the environment and people’s health?

A: The safe use of pesticides remains the best choice for control of insects occurring in such big numbers. It is important to use environmentally safe products which cause minimum harm to non-targets. Spray teams should be well trained on how to handle the pesticides.

People living in the invaded areas should also be alerted on keeping themselves and their livestock safe by not getting into the sprayed areas as advised. One effective biological control is the use of the Metarhizium, which the International Institute of Tropical Agriculture (IITA) developed out of the locust skin fungus.

Nevertheless, some chemicals may cause more harm to the environment, especially when aerial spraying is applied on swarms in flight. The pesticides can contaminate the environment, water, crops and can cause skin rashes or respiratory, neurological or eye problems. They can also cause harm to animals and aquatic species.

In times of locust outbreaks, like now, there is a tendency to procure large quantities of pesticides. However, once the locusts are gone, stockpiles of the unused pesticides remain. This brings about a new challenge of destroying or safely disposing of the old or obsolete pesticide stock.

Q: Can the locusts be eaten?

A: Many communities in the world eat locusts and other insects. It is, however, important to caution against eating sprayed locusts. Additionally, locust swarms can contain billions of locusts, so catching them for food may not have a significant effect in reducing their population.
