dc.description.abstract | In an evaluation of six insecticides cypermethrin (0.007%) resulted in the highest grain yield of cowpea by increasing the number of leaves and reducing the galerucid beetle infestation. This was followed by carbofuran (@ 1.5 kg a. i. / ha) + monocrotophos (0.07%) and carbofuran alone ( @ 1.5 kg a. i. /ha). While a significant ( P < 0.01) positive correlation ( r= 0.94) existed between the number of leaves and grain yield, it was negative ( r=-0.92) between grain yield and beetle infestation. The economic evaluation of the insecticides also proved that cypermethrin was the best (BCR=8.81) followed by carbofuran (BCR=5.57). | en_US |
