Abstract

Field research was conducted in 1982 and 1983 to characterize the persistence of fluridone {1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)pyridinone} in five Georgia soils. Fluridone persisted less than 365 days in all soils, with shorter persistence upon reapplication in 1983 which indicated the potential for enhanced microbial degradation. A significantly higher rate of loss in 1983 compared to 1982 was recorded in the Greenville sandy clay and Dothan loamy sand soils. A higher rate of loss was recorded for the 1.7 kg ai/ha than the 0.6 kg/ha treatment in the Bradson clay loam and Rome gravelly clay loam soils. No grain sorghum [Sorghum bicolor (L.) Moench. ‘BR 64’) injury was observed in a field bio assay planted in the spring of 1984. Herbicide leaching did not appear to be an important method of loss.
