Evaluate and develop postharvest treatments such as methyl bromide, CO2/SO2, phosphine, ozone, ultralow oxygen and cold treatments to eliminate invasive pests of concern to the California table grape industry that serve as trade barriers. The invasive pests of concern are spotted wing drosophila (SWD)(Drosophila suzukii), European grapevine moth (EVGM)(Lobesia botrana), and the newest invasive, the brown marmorated stink bug (BMSB)(Halyomorpha halys).
Utilize a cooperative effort between USDA-ARS, USDA-APHIS, California industry, and foreign counterparts to address pest-related barriers to export. Particular attention will be paid to the expansion and retention of export markets. Pests will be targeted with novel postharvest techniques including, but not limited to: fumigation, heat/cold treatments, and system-based approaches. Whenever possible, techniques will be tailored to infrastructural and logistical requirements with priority given to those that minimize interruption to conventional methods of production, storage, and distribution.
