Huge demands for crops have meant agricultural systems have simplified and frequently focused on single crops. In sub-Saharan Africa, female-headed households tend to experience lower postharvest losses across all crops, mostly due to quick adoption of improved storage technologies. Demonstration plots in Kenya show that genetically modified (GM) maize varieties are more effective in controlling insect attacks than their conventional counterparts — without the use of pesticides. Good management of maize through the production phases is important. H517 : Rainfall of about 7501000mm: 30: Tolerant to foliar diseases and pests.

At this stage, there are no apparent symptoms of fungal growth on the lesions. Western Kenya, Elgeyo Marakwet, Coffee growing areas of Central Kenya and parts of Nyanza. J Econ Entomol. 2: Sickle (left) and machete (middle) used for manual harvesting of maize; and stooks of maize in the field (right) Kalro develops maize varieties that can withstand pests News By Antony Gitonga | 26th Jul, 2020 Scientists from the Kenya Agricultural and Livestock Research Organization (KARLO) farm in Naivasha. maize growing in hot, humid, lowland tropical areas, where it causes no economic damage. Several species have been reported. The counties also represent regions in western Kenya where the push–pull cropping system has been widely adopted by smallholder maize farmers for pest management. In many African countries, the average maize yield per hectare is very low. For maize, threatening organisms are stem borers, nematodes, bacteria, viruses, fungi and weeds are some of the organisms that have a negative impact on the maize plant. farm maize storage systems in Kenya is limited. They have found to be efficient biological control agents against two major maize pests: the Cotesia typhae to control the maize stemborer, Sesamia nonagrioides, which has invaded France. Pesticides were used against a range of pests including fall armyworm (Spodoptera frugiperda J.E. Profitable maize farming in Kenya is becoming a reality for most farmers who are readily taking up new technologies to help them to drastically improve yield. The project also produces hermetic post-harvest bags in four African countries – Kenya, Malawi, Zambia and Zimbabwe – which protect harvested grains from attack by destructive pests, such as the larger grain borer (Prostephanus truncatus) and the maize weevil (Sitophilus zeamais). Has an excellent husk cover. Maize Farming Success Story. Insects … Kenya: New Bugs, Found in Kenya, Can Help to Control Major Maize Pests. iii 3. mays) known in many countries as corn or mielie/mealie, is a grain domesticated by indigenous peoples in Mesoamerica in prehistoric time The leafy stalk produces ears which contain seeds called kernels.Though technically a grain, maize kernels are used in cooking as a vegetable or starch. Stemborers: African maize stalkborer (Busseola fusca) Stemborers are the most important insect pests of maize in sub-Saharan Africa. The importance of a species varies between regions, within a country or even the same eco-region of neighbouring countries. Bt maize is expected to be commercialized by 2022 if it is approved by Kenya’s relevant government agencies, said Prof. Dorrington Ogoyi, chief executive officer of the country’s National … Fig. Follow the thumb images for additional images and information. Two species of these parasitoids have been discovered by us and our colleagues in Kenya. As a result of the pest protection provided by the Bt gene, the GM maize outperformed conventional varieties three-fold per hectare, according to the post-harvest evaluation of […] These insect pests of maize cause damage to the plant and these cause stress to the plant. A survey was conducted in 2014 to assess magnitudes of postharvest losses in on-farm maize storage systems in Kenya, and the contribution of rodents to the losses. 2016 Aug;109(4):1943-50. doi: 10.1093/jee/tow134. They have found to be efficient biological control agents against two major maize pests: the Cotesia typhae to control the maize stemborer, Sesamia nonagrioides, which has invaded France. utilization regions in Kenya where the majority of the farmers prac-tice smallholder mixed farming. A total of 630 farmers spread across six maize growing agro-ecological zones (AEZs) were interviewed. In Kenya, six maize-growing agroecological zones have been identified (Hassan et al., 1998); these include, from east to west, the lowland tropics (LT) on the coast, followed by the dry mid-altitude- and dry transitional zones around Machakos (Fig. Maize (Zea mays L. ssp. Infestation and damage by pests have been ranked as the third most important constraint upon maize production in semi-arid eastern Kenya after moisture stress and poor soil fertility (Songa et al., 2002). 2), or carried to the storage area. Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. MAIZE PESTS. The result of course represents unwanted pests to the farmer. Akoth grows maize on 0.7 hectares in Homa Bay, western Kenya. The Bt maize planted earlier in western Kenya is already showing resistance to the destructive stem borer and fall armyworm pests, which will … Low soil fertility, soil acidity, late land preparation and planting, poor weeding and even using the wrong planting methods can contribute to low maize yields. We meet 24 year old Babuh on his parents’ expansive 700 acre farm in Endebes town, Trans Nzoia County. He said maize variety which has been developed through biotechnology will not only help Kenya attain her food security challenges, but also manage losses resulting from stem-borer and other pests. Foliar (leaf) and stalk/ear rot diseases and stem-borers cause great losses in maize production in the humid transitional and high tropics of Kenya. Two species of these parasitoids have been discovered by us and our colleagues in Kenya. With an increasing world population to feed, a reduction of such losses can lead to substantial increases in food availability, particularly in the developing world (Boxall, 2001). Scientists at the Nairobi-based International Centre for Insect Physiology and Ecology (Icipe) have discovered ‘smart’ maize varieties that defend themselves from the destructive stemborer by summoning the natural enemies of the pest.
