Abstract:
On Farm Testing was conducted to assess the performance of white grub menace in sugarcane by ICAR KVK Bagalkote during 2019-20 and 2020-21 using two bio-pesticides i.e., Metarhizium anisopliae @ 5 kg/ac a technology recommended by UAS Dharwad and Entomopathogenic Nematodes (EPN) Heterorhabditis indica @ 3-4 kg/ac technology recommended by NBAIR, Bengaluru. Among these two treatments, soil application of M. anisopliae (4 x 10⁹ cfu @ 5 kg/ha) at the time of planting was significantly effective in reducing white grub population within 30th day of application and recorded highest cane yield of 107.52 t/ha when compared with application of EPN (H. indica) based formulation (102.09 t/ha), while treatment with chemical control measure with chlorpyriphos 20 EC (10 ml/lit of water for drenching) has given 92 t/ha yield in sugarcane. The results proved that, application of M. anisopliae is best when compared to conventional method of white grub control and application of EPN (H. indica).
