Abstract:
An experiment entitled “Evaluation of biorational insecticides against major pest complex of cucumber (Cucumis sativus L.)” was conducted at the All India Co-ordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra) during kharif 2022. During the course of study, six sequential strategies with untreated control were evaluated against sucking pest complex of cucumber. The results showed that treatment with spraying of Lecanicillium lecanii @ 5 g/l fb NSE 5% fb Metarhizium anisopliae @ 5 g/l was found to be most effective and recorded least average survived population of aphids, thrips and whitefly and it was at par with spraying of Lecanicillium lecanii @ 5 g/l fb Pongamia oil 0.5% fb Metarhizium anisopliae @ 5 g/l. However, treatment with spraying of Beauveria bassiana at 5 g/l fb Pongamia oil 0.5% fb Metarhizium anisopliae at 5 g/l observed as safer and recorded highest coccinellid grub population which observed at par with spraying of Beauveria bassiana @ 5 g/l fb NSE 5% fb Metarhizium anisopliae @ 5 g/l.
