Abstract: This proposed project addresses management of grape berry moth (GBM), a key pest of grape throughout Virginia, grape root borer (GRB), a pest that has been sporadic in occurrence but locally severe, and Pierce?s disease (PD), a sharpshooter-borne disease that is of critical concern in the southeastern part of the state. The objectives attempt to deal both with short-term control options, as well as ecological factors that can be used to manage these pests more effectively in the long term. 1. Evaluate role of vineyard surroundings and management approach on incidence of GBM, parasitism of GBM, climbing cutworm pest pressure, diversity of arthropod predators, and abundance of sharpshooter vectors of Pierce?s disease, 2. Compare efficacy of low-risk insecticides for grape berry moth, 3. Evaluate mating disruption technologies, as well as three non-organophosphate pesticides: azadirachtin (botanical), methoxyfenozide (insect growth regulator) and paraquat (herbicide) for control of GRB, 4. Evaluate three trap designs leading towards a GRB monitoring program, 5. Evaluate efficacy of two neonicotinoids for prevention of PD infection.
Description:
Impact:
This project will enable growers to control three pests in vineyard: GBM, a key pest of vineyards in most years, GRB, a sporadic pest but very damaging in some vineyards and with no adequate control measures, and Pierce's disease. The project will provide a better understanding of the status of PD and its sharpshooter vectors that may prove vital with warming winter temperatures.
