Abstract

Study on relative toxicity of different insecticides/ herbicides on grubs and adults of Zygogramma bicolorata revealed that chlorpyriphos 0.05 per cent, atrazine 1 kg a.i. per ha, thiomethoxam 0.005 per cent, glyphosate 1 kg a.i. per ha, metribuzin 1 kg a.i. per ha and imidacloprid 0.005 per cent were most toxic to the grubs and adults. Endosulfan 0.075 per cent were moderately toxic to the grubs and adults and dimethoate 0.03 per cent was found moderately toxic to the adults. Moreover, 2, 4-D sodium salt 1 kg a.i. per ha was found to be least toxic to the larvae and adults of Z. bicolorata.
