Abstract:
Efficacy of different acaricides against mite infesting okra revealed that among the all treatments, the most effective treatment was Fenazaquin 10 EC 0.016%, resulting in the lowest mite population, at par with Fenpyroximate 5 SC 0.003%. The next best treatment was Spirotetramat 15.3 OD 0.018%, which was at par with Diafenthiuron 50 WP 0.060%. Spiromesifen 22.9 SC 0.023% was moderately effective, which was at par with bifenazate 22.6 SC 0.006% and Etoxazole 10 SC 0.008%. Spirotetramat 11.01 + Imidacloprid 11.01 SC 0.02202% and Propergite 50 + Bifenthrin 5 SE 0.1265% were less effective. However, the highest mite population was recorded from the control plot. Out of the nine acaricidal treatments evaluated, fenazaquin 10 EC 0.016% proved to be the most effective against okra mite. It exhibited the lowest mitepopulation, maximum fruit yield, and highest yield increase over the untreated control and the highest net return. Among the various acaricidal treatments, fenpyroximate 5 SC0.003% obtained the highest CBR (Cost Benefit Ratio) of 1:65.69, followed by fenazaquin 10 EC 0.016% with CBR of 1:30.80.
