Vine Mealybug on Grape

Vine mealybug is one of the most prolific pests of table grapes. Its exponential growth rate and affinity for feeding within clusters close to harvest make its management of highest priority for grape growers dealing with infested vineyards. We have conducted several in-season and post harvest trials to evaluate new insecticides for treatment of vine mealybug as well as conducted several season-long control programs for vine mealybug in Kern County. We are currently continue work on in-season management of the vine mealybug by evaluating new insecticides with different modes of action for resistance management.
