Yes, you may use Sevin Concentrate on grapes for labeled pest control. Mix 3.0 fl. oz. of product per gallon of water and spray upper and lower leaf surfaces and between fruit clusters and on small limbs and trunks to the point of runoff where pest appear. Repeat applications as necessary up to a total of eight times per year for tree fruits or five times per year for small fruits, but not more often than once every seven days.
