Bio-Efficacy of Chlorantraniliprole 600 g/l SC against Sugarcane Early Shoot Borer, Chilo infuscatellus (Snellen)

Sugarcane (Saccharum spp.) is one of the most important commercial crops grown mainly for sugar, jaggery and bio energy. The early shoot borer, Chilo infuscatellus Snellen is considered to be most destructive insect inflicting severe damage in early growth stage. To evaluate the bio-efficacy of chlorantraniliprole 600 g/l SC against sugarcane early shoot borer, experiment was conducted during 2020-21 and 2022-23 at RARS, Anakapalle. The results indicated that, chlorantraniliprole 600 g/l SC @ 100 g a.i ha-1 recorded lowest dead heart damage (2.23-2.31%) with highest per cent pest reduction over untreated control (88.49-88.69 %), however it was statistically on par with chlorantraniliprole 600 g/l SC @ 75 g a.i ha-1. Untreated control treatment recorded at highest per cent dead heart damage (19.37-20.43 %). The yields recorded were 90.69-93.67 tha-1 in the treatment chlorantraniliprole 600 g/l SC @ 100 g a.i ha-1, whereas untreated control recorded lowest yields of 56.32-58.34 tha-1. During both the years, there was no ill effect after treatment imposition was observed on the population of coccinellids and spiders.
