Abstract

Investigations were carried out to evaluate phototropical, mechanical and botanical control measures in comparison with chemical treatment for managing sucking pest complex of okra under field condition in Dr. PDKV, Akola during kharif, 2019. The results regarding the cumulative effect revealed that treatment Recommended insecticidal spray (Ist Spray and IIIrd Spray with Imidacloprid 17.8% SL, IInd Spray and IVth Spray with Fenvalerate 20% EC) emerged as the most effective treatment against aphids, leafhoppers and whiteflies with realized yield of 52.23 q/ha. It was at par with non-pesticidal treatment Removal of infested shoots + Light traps + NSE (5%) + Yellow sticky trap with yield of 44.49 q/ha followed by Light traps + NSE (5%) in case of leafhopper population whereas in case of aphid and whitefly population treatment Removal of infested shoots + NSE (5%) + Yellow sticky trap at 3, 7 and 14 days after application.
