IN-SEASON CONTROL OF VINE MEALYBUG IN ‘AUTUMN ROYAL’ TABLE GRAPES IN KERN COUNTY, 2009

In 2009 we conducted a field trial to evaluate the effects of insecticides against vine mealybug. The trial was located in a 2.0 acre portion of a vineyard planted with ‘Autumn Royal’ table grapes near Arvin, Kern Co. CA. We evaluated effects of 17 treatments and an untreated check (Table 1) on mealybug density in plots that were two rows by 9 vines long and organized into a RCBD with four blocks.
