(Wines&Vines) - A proliferation of vine mealybug (VMB) has many grapegrowers on California's Central Coast returning to the drawing board for treatment options. 

“It’s definitely increased,” Greg Miller, Central Coast field representative for insecticide manufacturer Nichino America, says of the recent outbreak. “Viruses like red blotch and leafroll are waking a lot of growers up to the severity of what mealybugs are doing.”
