Mr Aloice Ndiege examines napier grass growing ready for Push Pull farming in the Allelochemic screen house at the International Centre of Insect Physiology and Ecology( ICIPE), Mbita district, Lambwe division, Kenya. The basic idea of Push Pull farming is to plant desmodium beside the corn crop. The desmodium pushes the pests away from the corn. The 'Pull' plant is called napier grass and is grown around the perimeter of the crop. Napier grass attracts the pests and in turn pulls the pest away from the crop. The technique invented by Professor Khan and has transformed the lives of ecological farmers around the African region.
