Abstract

Effect of intercropping of greengram, cowpea, blackgram and soybean in maize and sorghum on the incidence of stem fly, whitefly, yellow mosaic and pod borer of pulses and shoot fly and stem borer of cereals indicated no significant effect on the pests except stem fly in blackgram, whitefly in cowpea, yellow mosaic and pod borers in green gram. Stem fly in blackgram and whitelly in cowpea were high when intercropped with maize. Greongram had low incidence of yellow mosaic when intercropped with maize and sorghum than raised as pure crop. Pod borer damage in greengram was significantly lesser in pure crop than raised with maize and sorghum. There was no difference in shoot fly and stem borer of sorghum and maize between pure crop and mixed with intercrops.
