We investigated the potential of layering separate insect and disease management tactics together to determine the efficacy of such an approach on limiting the occurrence of Pierce's disease in grapes. Our results indicated a combination of choronicotinyl insecticides and a foliar barrier (kaolin) are most successful in reducing vector pressure and lowering the incidence of Pierce's disease. Unfortunately, while the above treatments did reduce the incidence of PD relative to controls, they still suffered an approximate average of 30% infections (30% of the treated plants showed symptoms after 1.5 years. Control treated plants displayed as average of 69% infection.
