** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** BARLEY YELLOW DWARF VIRUS IS TRANSMITTED BY SEVERAL SPECIES OF CEREAL APHIDS AND HAS BEEN A THREAT TO WINTER WHEAT IN THE SOUTHEASTERN USA IN RECENT YEARS. INTEGRATED PEST MANAGEMENT (IPM) IS THE MOST EFFECTIVE APPROACH TO MANAGING BYDV AND APHIDS. HOWEVER, THE RECOMMENDED STRATEGIES IN THE SOUTHEASTERN USA (I.E., PLANTING DATE, SEED TREATMENT, AND/OR TIMING OF FOLIAR INSECTICIDE APPLICATION) ARE BASED ON INFORMATION GENERATED MORE THAN TWO DECADES AGO, WHICH NO LONGER FIT TO OUR CURRENT CLIMATE PATTERNS OR BEST MANAGEMENT PRACTICES. THIS PROPOSAL AIMS TO PROVIDE RESEARCH-BASED SUPPORT FOR THE EFFECTIVE MANAGEMENT OF BYDV AND CEREAL APHIDS IN WINTER WHEAT IN THE SOUTHEASTERN UNITED STATES AND DEVELOP MUCH-NEEDED, UP-TO-DATE EDUCATIONAL MATERIAL TO PREVENT THE UNNECESSARY APPLICATION OF INSECTICIDES AND PROMOTE THE IMPLEMENTATION OF IPM. WE WILL ALSO PROVIDE ESTIMATES OF EXPECTED REVENUE ASSOCIATED WITH IMPLEMENTING EACH PRACTICE AND DEVELOP A CALCULATOR AND EDUCATIONAL MATERIAL TO ASSIST PRODUCERS WITH THE DECISION-MAKING PROCESS.
