Huge demands for crops have meant agricultural systems have simplified and frequently focused on single crops. During a sensitization workshop held at Kenya Sugar Research Institute in Kisumu, the county chiefs said the Bt maize planted earlier in Western Kenya under the National Performance Trials (NPT) has shown resistance to destructive stem-borer and fall armyworm pests. utilization regions in Kenya where the majority of the farmers prac-tice smallholder mixed farming. 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. Farmers are advised to grow maize varieties that do well in their agro-ecological regions as shown in the map. Fig. In the media 5 Oct 2020 Efforts in controlling maize disease boosting steady supply of certified seeds Gender aspects of managing pests in stored maize In Kenya and Malawi, women farmers who manage metal silos for storing maize have improved their standing in their communities and their self-esteem. 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. I here present some of the organisms that inhabit maize fields in Kenya. Maize Farming Success Story. 6 months ago; 5 Minute(s) to read ; Insect pests, such asmaize stemborers and fall armyworm, increasingly challenge food production around the world. 2016 Aug;109(4):1943-50. doi: 10.1093/jee/tow134. Constraints for maize production include drought, low soil fertility, pests and diseases. Highland maize varieties are grown on some 40-50% of the total maize area, representing 600,000 - 800,000 Ha. Good management of maize through the production phases is important. A total of 630 farmers spread across six maize growing agro-ecological zones (AEZs) were interviewed. 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. 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.

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. J Econ Entomol. 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. Maize stalks are cut using sickle and machete (panga) and stooked on farm (Fig. Stemborers: African maize stalkborer (Busseola fusca) Stemborers are the most important insect pests of maize in sub-Saharan Africa. 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. 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. Push–pull technology is an intercropping strategy for controlling agricultural pests by using repellent "push" plants and trap "pull" plants. In the past, she stored her grain in a traditional granary: a structure built with mud, branches, and cow dung that allows free entry to the maize weevil and the larger grain borer, the two most damaging pests of stored maize in Africa.
