Utilization of Plant Extracts for Managing Fruit Borers in Okra, [Abelmoschus esculentus (L.) Moench]

Abstract

A field experiment was conducted to study the bio efficacy of seven plant extracts viz., neem oil 0.3%, neem seed kernel extract 5%, azadirachtin 0.15 EC 0.0006%, Aloe vera extract 1%, Citrulluscolo cynthis leaf extract 1%, garlic bulb extract 3% and neem leaf extract 10% against fruit borers during summer and kharif, 2016 at Main Vegetable Research Station, Anand Agricultural University, Anand (Gujarat). Among seven different plant extracts tested, neem oil 0.3% and azadirachtin 0.15 EC 0.0006% observed with lowest number of larvae and per cent fruit damage followed by NSKE 5% and garlic bulb extract 3% during both the seasons, while remaining plant extracts i.e. Aloe vera extract 1% and Citrulluscolo cynthis leaf extract 1% found poor to manage fruit borers. The highest marketable okra fruits were recorded from the plots treated with azadirachtin 0.15 EC 0.0006% (55.60 and 116.41 q/ha) and neem oil 0.3% (52.58 and 118.25 q/ha) followed by NSKE 5% (50.80 and 111.89 q/ha) during summer and kharif season, respectively.
