Abstract

In the preliminary trial, spraying diflubenzuran (Dimilin) 25 WP @ 100 g a.i./ha on groundnut brought 50 per cent reduction in larval and 30% in pupal stages of leaf miner. The order of efficacy in the control of leaf miner and reduction in leaflet damage was decamethrin 0.01% chlorpyriphos 0.05% monocrotyophos 0.05% quinolphos 0.05% diflubenzuran 0.016% dimethoate 0.1% and that of securing higher yield, the order was monocrotophos decamethrin chlorpyriphos dimethoate fenvalerate diflubenzuran. In the confirmatory trial, diflubenzuran 1.6 kg/ha followed by phosalone (750 ml/ha) and chlorpyriphos (2 lit/ha) recorded less leaf miner damage and higher pod yield.
