Online published on 29 July, 2022. Abstract Scelodonta strigicollis is a notorious leaf damaging pest in Tamil Nadu in grapes and responsible for considerable yield loss. Effect of a new biological insecticide molecule, spinetoram 12 SC alone and in combination with buprofezin 25 SC 375 g a.i./ha, carbendazim 50 WP 125 g a.i./ha and urea (2%) was studied on S. strigicollis at field conditions during 2012 and 2013 kharif seasons. The results of the field experiments showed that spinetoram 12 SC 45 g alone and in combination with buprofezin 25 SC 375 g a.i./ha, carbendazim 50 WP 125 g a.i./ha and urea (2%) were significantly effective in minimizing the S. strigicollis when sprayed thrice at 15 days interval and increases the fruit yield. All the tested doses of spinetoram 12 SC 45 g alone and in combination with buprofezin 25 SC 375 g a.i./ha, carbendazim 50 WP 125 g a.i./ha and urea (2%) were showed nil phytotoxic symptoms on grapes plants.
