Studies for the Control of Citrus Pests in the Punjab

The results of this field experiment for the control of major citrus pests viz., citrus psylla (Diaphorina citri), citrus leaf-miner (Phyllocnistis citrella), citrus mite (Eutetranychus orientalis) and citrus white-fly (Dialeurodes citri) reveal that monocroto-phos and dimethoate gave the best results during both the years under observations. This was closely followed by malathion + DDT and endosulfan. Next in order of efficacy were foimothion, methyl demeton and malathion.
