abstract
Leucinodes orbonalis Guenee (Pyraustidae: Lepidoptera) is the key pest of eggplant (also known as brinjal and aubergine). The yield loss due to this pest is to the extent of 70-92 per cent. Five doses of cyazypyr 10% OD (60, 75, 90 and 105g a.i./ha in both the year 2011 and 2012) were sprayed every year for their efficacy along with fipronil 5% SC @ 60 g a.i./ha, Flubendiamide 40% SC @ 30g a.i./ ha and Profenofos 50% SC @ 500 g a.i./ ha as a standard check. In both the seasons 2011 and 2012, cyazypyr 10% OD @ 105 and 90g a.i./ha were superior to most of the other treatments in respect of per cent shoot infestation. Cyazypyr @ 105g a.i./ha, however, was superior to its 90g a.i./ha dose after 10 days of 2^nd and 4^th spray. Flubendiamide 40% SC @ 30g a.i./ha, fipronil 5% SC@ 60g a.i./ha and profenofos 50% EC @ 500ga.i./ha were on a par among them in per cent shoot damage in most of the observations. Flubendiamide, however, showed similar performance with cyazypyr 10% OD @ 90g a.i./ha in a few cases. Cyazypyr 10% OD @ 75 g and 60g a.i./ha were ineffective, and it is also safer to natural enemies.
