Abstract

In 2-year experiment 8 pest management schedule alongwith control were tested in the field against the major insect pests of okra including leafhopper (Amrasca biguttula biguttula), whitefly (Bemesia tabaci) and shoot and fruit borer (Earias vittella and E. insulana). The integrated schedule (S4) comprising sprayings of S3 + spinosad 45 SC @ 0.4 ml/1 at 15-day interval starting from fruit initiation was found most effective in reducing the population of leafhopper (1.10 nymph/3 leaves), whitefly (2.14 adults/3 leaves) and fruit borer shoot damage (1.07%) with infestation on number (2.50%) and weight (2.72%) basis. This schedule showed significant increase in the yield (95.86 q ha−1) over control followed by S3 and S5.
