Circumventing Ovicidal Deficiencies of Sulfuryl Fluoride and Other Postharvest Fumigants

Complete normal atmospheric pressure testing and then scale vacuum and normal atmospheric pressure fumigation toward commercial scale applications with validation. Specific objectives of the research include: 1) Conduct insecticidal efficacy trials at temperature < 70ºF (i.e., 50 & 60ºF), 2) Begin scaling fumigations toward commercial scenarios, and 3) Determine the environmental factors (e.g., temp, air flushes, etc.) that minimize chemical residues associated with ovicide-sulfuryl fluoride pairings, particularly those resulting from the propylene oxide-sulfuryl fluoride mixture. Tailor fumigant-ovicide application to minimize residue formation.
