Abstract

Field trials were conducted to evaluate insecticides with different mode of action against the mite infestation in chilli cv. Utkal Ava. The seeds were treated with imidacloprid 600 FS @ 5 ml/kg in all the treatments except untreated control plot and were subjected to foliar spray with acetamiprid 20 SP @ 10 g a.i./ha, spinosad 45 SC @ 73 g a.i./ha, fenpyroximate 5 EC @ 30 g a.i./ha, emamectin benzoate 5 SG @ 10g a.i./ha, fipronil 80 WG @ 50g a.i./ha, spiromesifen 22.9 SC @ 96 g a.i./ha, acephate 75 SP @ 500 g a.i./ha and dimethoate 30 EC @ 300 g a.i./ha at 30 and 45 days after transplanting in different treatment modules. The pooled data over three seasons reflects that spiromesifen was the most effective among the tested insecticides, scored minimum population of mites (0.27 mites/leaf), maximum number of beneficial coccinellid predators (2.62 coccinellid predators/leaf), highest yield (92.1q/ha) and additional net income (` 4630/ha). Spiromesifen is a spirocyclic phenyl substituted tetronic acid belongs to ketonol class which inhibits lipogenesis, prevents insects from maintaining water balance cause desiccation, mites dries up and dies.
