Bio-efficacy of newer insecticides and bio-pesticides against termite on chickpea in arid region of Rajasthan

Abstract

The seed treatment, as well as soil application of imidacloprid 600 FS @ 5 ml/kg + Beauveria bassiana 1.15 WP @ 2 kg /ha, was found most effective against termite (9.34% plant damage) after 110 days of crop sowing, followed by fipronil 5 SC @ 5 ml/ kg + Metarrihizium anisopliae 1.15 WP @ 2 kg/ha (10%) and clothianidin 50 WDG @ 2 g/ kg + Beauveria bassiana 1.15 WP @ 2 kg /ha (10.62%). The treatments alone seed treatment of imidacloprid 600 FS @ 5 ml/ kg seed (11.56%) followed by fipronil 5 SC @ 5 ml/ kg seed (12.03%) and clothianidin 50 WDG @ 2 g/ kg seed (12.65%) were found moderately effective while, bio-pesticides viz., Metarrihizium anisopliae 1.15 WP @ 2 kg/ha and Beauveria bassiana 1.15 WP @ 2 kg /ha with 15.78 and 15.47 per cent plant damage were found least effective for controlling the termite population. The maximum yield was obtained in imidacloprid 600 FS + Beauveria bassiana 1.15 WP (18.70 q ha-1) followed by fipronil 5 SC + Metarrihizium anisopliae 1.15 WP (18.20 q ha-1) and clothianidin 50 WDG + Beauveria bassiana1.15 WP (18.00 q ha-1), respectively.
