The degradation of diflubenzuron and its chief metabolites in soils. Part III. Fate of 2,6‐difluorobenzoic acid

摘要

Abstract2,6‐Difluorobenzoic acid, one of the two primary diflubenzuron metabolites, is rapidly and completely degraded in soil. Times to 50 disappearance were 9 and 12 days in two agricultural soils. 14CCarbon dioxide was an ultimate product of the ring‐14C‐labelled compound. A part of the radioactivity, increasing with time to one third of the applied dose of 1 mg kg−1, could not be extracted from t
