Relative Efficacy of Some Pesticides in the Control of Citrus Pests

The results of this experiment suggest that among dimethoate 0.04 per cent, malathion, 0.05 per cent and fenitrothion 0.04 per cent, dimethoate had a slight edge over malathion which in turn proved better than fenitrothion in controlling citrus psylla, mite, aphid and leaf-miner. Among malathion 0.03 per cent 4- DDT 0.1 per cent, endosulfan 0.04 per cent and endrin 0.02 per cent, malathion + DDT proved better than endosulfan which in turn was superior to endrin in controlling the pests viz., leaf-miner, white-fly and mite.
