Seasonal Incidence and Eco Friendly Management of White Grub in Sugarcane Using Entomopathogenic Nematode and Entomopathogenic Fungus in Andhra Pradesh, India

High rainfall with increase in humidity (68% to 75%) along a decrease temperature ( 3 5°C less than usual ) during June, July, and August months favor the emergence of white grub beetles, its egg laying which turn resulted severe sugarcane clump damage by grubs September months. Seasonal incidence growing areas Andhra Pradesh state showed that clumps caused infestation was significantly high march ratoon compared February crop; January plant crop low seedling crop. Grub recorded 4 age 6 7 Field efficacy entomopathogenic nematode fungus management grub, Holotrichia consanguinea investigated promoted biocontrol endemic 2017-18 2019-20. Entomopathogenic (Heterorhabditis indica NBAII-H38), fungi (Metarhizium anisopliae (NBAIR Ma4 )along chemical Chlorantraniliprole were evaluated through soil application. The results indicated Heterorhabditis NBAII-H38 (12 kg a.i./ha) application two times at monthly interval higher reduction damage. Metarhizium NBAIR (2.5 treated plots percentage chlorantraniliprole treatment. nematode, fungus, found effective insecticidal grub. Cost benefit agents, H. proved superior application.
