Abstract
Efficacy of five commercial modern biopesticidal formulations was evaluated against the penultimate instar larvae of E. machaeralis in field-cum-lab experiments. These were; plant derived product (Ozomite® @ 0.0025% to 0.02%), Beauveria bassiana with combinations of other entomopathogenic fungi (Bioseal plus® @ 0.05% to 0.30%, i.e., 5x105 to 3.0x106 spores/ ml) and Metarhizium anisopliae with combinations of other entomopathogenic fungi (Biomet plus® @ 0.05% to 0.30%, i.e., 5x105 to 3.0x106 spores / ml), Actinomycete product (Spinosad) 45%EC (Conserve® @ 0.005% to 0.10%), botanicals with Bacillus thuringiensis (AgropestBt® @ 0.01% to 0.05%) apart from water spray as control. The plant derived commercial formulation (Ozomite®) (with 94.44% mortality at 0.01%), Actinomycete product (Conserve®) (with 100% mortality at 0.05%) and botanicals with Bt (AgropestBt®) (with 77.78% mortality at 0.05%) proved promising against the Eutectona machaeralis larvae. The plant derived commercial formulation (Ozomite®) was the most effective, followed by Actinomycete product (Conserve).
