Abstract

Field experiments to evaluate the effect of three types of insecticides on the yield and control of cowpea insect pests were conducted in two agro-environments simultaneously in Enugu Area, South Eastern Nigeria in 2007. cropping season. Sherpa plus 280 EC (30g/litre
cypermethrine + 250g/litre dimethoate) as water emulsifiable concentrate, furadan 10 G (carbofuran), neem emulsion (Azadiracta
indica) as insecticide treatments and two cowpea varieties (Ife brown and potiskum as cowpea variety treatment were used in the
experiments. TheĀ  experimental design was a split plot in a randomized
complete block (RCB) replicated three times. Sherpa plus 280 EC was more effective in controlling cowpea insect pests than furadan 10 G and neem emulsion and itsĀ  effectiveness is not affected by variation in location. In Nsukka, potiskum yielded significantly higher than Ife
brown, whereas in Enugu, there was no significant yield difference between the two varieties.
