 ABSTRACT

Investigations were carried out at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif, 2015 for bio-efficacy of various biopesticides on the incidence of sucking pests viz., aphids (Aphis craccivora Koch), jassids (Empoasca kerri Pruthi), whiteflies (Bemisia tabaci Gennadius), thrips (Thrips palmi Karny) and flower thrips (Megalurothrips usitatus Bagnall) in green gram. Among the various biopesticides evaluated for their field efficacy against sucking pests, tobacco decoction (2 %) extracted either with hot or cold water found more effective followed by Beauveria bassiana(0.1%, 1 x 1010 CFU/ g). Azadirachtin recorded the highest thrips population and failed to protect the crop as it was at par with control.The effectiveness of these treatments also reflected on green gram yield. Higher Incremental Cost Benefit Ratio (ICBR) was also obtained in these treatments.

Key words: Biopesticides, Sucking pests, Tobacco decoction hot or cold, B. bassiana, Neem oil, NSKE, L. lecanii, Azadirachtin.
