Ultra Blazer in Peanuts small weeds before 65 DAP surfactant pts/A
Classic Issues in Peanut 20-25% of acreage late-season beggarweed tolerance of new varieties influence on TSWV
Does Classic have an influence on TSWV in peanut? Studies conducted in indicate….. Classic can increase TSWV but not always. Classic/TSWV interaction can reduce yields but not always. Earlier applications??
