Abstract

Chemical control of major pest complex of radish grown for its edible root was studied over three seasons at Bangalore. Results revealed that insecticide sprays were not necessary when the crop is either attacked by flea beetles alone or by flea beetles and lepidopterous pests at late crop growth stages, since it did not affect the marketable yield. However, there was a need to resort to insecticide sprays when the crop was attacked by both flea beetles and mustard sawfly. Signi- ficant reduction of both the posts was observed after application of 0.07% endosultan, 0.05% monocrotophos, 0.07% phosalone, 0.05% methyl parathion, 0.01% fenvalerate and 0.0014% deltamethrin, with a consequent increase in yield.
