Description
Investigations were carried out on the effect of biorational insecticdes against sucking pests of okra during 2015-16 at the ICAR-Indian Institute of Horticultural Research, Bengaluru. The major sucking insects studied were leafhopper, Amrasca biguttula biguttula Ishida, whitefly, Bemisia tabaci Gennadius, and aphid, Aphis gossypii Glover. All the tested biorationals reduced the sucking pest populations significantly over control. Two sprays of spinosad 45 SC @ 0.2 ml/l, dimethoate 30 EC @ 1.6 ml/l and azadirachtin 10,000 ppm @ 1.0 ml/l were effective.
