Abstract
Growing sorghum in association with cowpea or lablab reduced sorghum stem borer infestation. On sorghum as a pure crop, 32.6% stem borer damage was recorded, while intercropped with lablab or cowpea it was 9.2 and 16.4% respectively. Sorghum raised with lablab or cowpea yielded 4652 and 4567 kg of grain per ha respectively while pure sorghum yielded 3509 kg. When the phytochemicals extracted from the legumes lablab or cowpea were sprayed on sorghum they prevented oviposition by gravid females of C. partellus for up to six days.Keywords
