Field evaluation of the efficacy of Ferterra 0.4 GR, a new formulation of chlorantraniliprole was done against grapevine stem borer during 2014–15 and 2015–16. The results revealed that the stem borer activity indicated by the live holes with amount of frass collected from the live hole ceased successfully with its soil application at the root zone @ 15 g/vine. This application achieved maximum reduction (100% at 35 to 45 days after treatment) in the live holes in 2014–15; and in 2015–16, this reduction lasted up to 55 days, with 100%in the live holes. The standard check-dichlorvos stem injection (80ml/l), though was effective up to 20 days of the treatment, its effect decreased towards 55 to 60 days after treatment, and it was almost on par with the untreated check. The maximum grapevine berry yield was also obtained with chlorantraniliprole soil application; 15 g/vine was observed to be on par with higher doses (20 and 30 g/vine).
