Bioefficacy of various formulations of biopesticides against white grub, Leucopholis lepidophora infesting sugarcane under field condition

Abstract

Field experiment was conducted on the “Bioefficacy of various formulations of biopesticides against Leucopholis lepidophora (Blanchard) infesting sugarcane crop” during 2016-2017 at farmer’s field in endemic area of pest in Kolhapur region during 2016-2017. In field studies the various formulations of EPNs, EPF Metarhizium anisopliae and Beauveria bassiana were tested for their efficacy against grubs of L. lepidophora (Blanchard). The treatment with M. anisopliae-talc base @ 5 gm per litre was found to be significantly superior over untreated control and recorded 9.36 per cent clumps mortality at 60 DAT. Treatment with Entomopathogenic Nematode-Powder @ 5 gm per litre showed 11.68 per cent clumps mortality at 60 DAT were next in order of efficacy. Treatment with Entomopathogenic Nematode-spong formulation, Entomopathogenic Nematode Granules were next in order of efficacy.
