The experiment entitled “Efficacy of biopesticides against white grub, Leucopholis lepidophora (Blanchard) infesting sugarcane” was conducted in 2019-20 the field experiment on sugarcane ratoon with nine treatments, replicated thrice in the ‘Randomized Block Design’ with gross plot size 5×5 m on farmers field Mr. Ashok Patil, At/Pt. Gudal, Tal. Radhanagari, Dist. Kolhapur with the objectives, to study the efficacy of biopesticides available in market for the management of white grub under field condition and to study combined effect of biopesticides against white grub under field condition. The treatments for field experiment consisted of Metarhizium anisopliae (Grub Guard), M. anisopliae (NBAIR – Ma4), EPN- H. indica (Grub Nash), EPN- H. indica (Solider), EPN- H. indica (Neema Power), Urva Pinaca, Chlorpyrifos and untreated control. In the field experiment, M. anisopliae(NBAIR – Ma4) + EPN (Grub Nash) recorded lowest clump mortality about 10.81 per cent and 11.42 per cent with that of untreated showing 24.10 per cent and 21.95 per cent in first and second application, respectively. EPN (Grub Nash) was next in the order of efficacy which recorded 12.57 and 14.46 per cent clump mortality and M. anisopliae(NBAIR – Ma4) followed next in order with 12.69 and 15.28 per cent of clump mortality, respectively. Treatment UrvaPinaca found to be least effective against white grub control. The next safe insecticide was Chlorpyrifos. M. anisopliae(NBAIR – Ma4) + EPN (Grub Nash) recorded highest cane yield. Also, considering the B:C ratio and ICBR ratio M. anisopliae (NBAIR – Ma4) + EPN (Grub Nash) proves to be superior with 3.06 B:C ratio and 9.61 ICBR ratio of M.anisopliae (NBAIR Ma4) which is highest among all. Considering the above observations, M. anisopliae (NBAIR – Ma4) + EPN (Grub Nash) proves to be superior among all. The next best treatment in all aspects EPN (Grub Nash), followed by M. anisopliae (NBAIR- Ma4) and M. anisopliae(Grub Guard).
