Abstract
The metabolic fate of the plant growth regulator 2,3,5-triiodobenzoic acid was determined in soil using 14C-carboxyllabeled 2,3,5-triiodobenzoic acid. 1-14C-2,3,5-Triiodobenzoic acid was degraded to 14CO2 by the microflora in soil; no radioactive CO2 was evolved from sterilized soil. Following incubation of 1-14C-2,3,5-triiodobenzoic acid in soil, unchanged 2,3,5-triiodobenzoic acid and three metabolites (2,5-diiodobenzoic acid, 3,5-diiodobenzoic acid, and one unknown) were recovered. Peak concentrations of 2,5-diiodobenzoic acid and 3,5-diiodobenzoic acid were 15–20 and 14–15%, respectively, at 8 weeks of incubation and decreased thereafter.
