Abstract:
The present study entitled, bioefficacy of different acaricides against red spider mite, Tetranychus urticae Koch on brinjal, Solanum melongena L. was carried out during rabi 2020-2021. Spiromesifen 22.90 SC @ 96 g a.i./ha was superior treatment with minimum average survival population of mites (0.37 mites/sq.cm/leaf) and also recorded highest marketable fruit yield of brinjal (16.77 tonns/ha). However, it was followed by fenazaquin 10 EC @125 g a.i./ha and propargite 57 EC @ 570 g a.i./ha with 0.53 and 0.90 mites/sq.cm/leaf, respectively and were at par with each other. The treatment with spiromesifen 22.90 SC @ 96 g a.i./ha was also found superior by recording highest reduction in average survival population of mites (96.69%). Highest ICBR (1:21.10) was recorded in fenpropathrin 30 EC @ 75 g a.i./ha, followed by propargite 57 EC @ 570 g a.i./ha (1:13.13) and spiromesifen 22.90 SC @ 96 g a.i./ha (1:12.78).
