Online published on 9 August, 2019. Abstract Grapevine thrips, Rhipiphorothrips cruentatus pose an increasing threat to grapes cultivation in all the grape growing areas in India by causing scab formation on berries resulting in heavy yield loss. The combination products spinetoram 10% w/w WG + sulfoxaflor 30% w/w WG were evaluated against thrips at Odaipatty village of Chinnamanur block, Theni District, T.N. which is a traditional belt for grapes cultivation. Three rounds of foliar application of spinetoram 10% w/w WG + sulfoxaflor 30% w/w WG @350 ml/ha and spinetoram 10% WG + sulfoxaflor 30% WG @ 300 ml/ha were superior and effective in reducing the thrips damage on leaves and berries, which also recorded higher fruit yield and Cost-Benefit Ratio.
