Botanicals and Egg Parasitoids against Okra Shoot and Fruit Borer (Earias Vittella Fab.) in Okra

Abstract

A field experiment was conducted in the farm of Agriculture Research Institute Tando Jam, during April 2017 to August 2017. The highest percent of shoot infestation i.e (25.89) was recorded in T8 which was statistically different from all other treatments and followed by T3 and T7 at 7 days interval. Considering the percent reduction of shoot infestation over control, the maximum reduction (96.50) was recorded in T5 which followed by T6 (86.47). In that order, the minimum percent of flower bud infestation (11.11) was recorded in T5 followed by T6, T4, and T1. Furthermore data indicated that the maximum flower bud infestation noted in T8 followed by T3 and T7. Whereas, the lowest flower bud infestation (0.91%) was recorded in T5, T6, T4, T2 and T1. The further results discussed that at early fruiting stage of the okra, the maximum % of fruit infestation was observed in T8 followed by T3 and T7, while the lowest infestation (0.33%) was recorded in T5 followed by T6, T4, T1 and T2. It was also revealed that the fruit infestation was increased at the mid fruiting stage as a result the trend of percent reduction of fruit infestation over control caused by okra shoot and fruit borer due to application of different management practices was T5> T6 > T4 > T1 > T2 > T7 > T3 respectively.
