Degradation of 1,3-dichloropropene in aerobic soils
- DowElanco, Indianapolis, IN (United States)
The degradation of the soil fumigant, 1,3-dichloropropene (1,3-D), was investigated to determine its rate of degradation and the identify of metabolites in aerobic soils. Studies were conducted in the dark at 25{degrees}C with uniformly {sup 14}C-labeled 1,3-D at a concentration of approximately 100 ug/g on three soils: Wahiawa silty clay, Catlin silt loam and Fuquay loamy sand. Aerobic soil half-lives for 1,3-D were 1.8, 11.5 and 52.5 days on the Wahiawa silty clay, Catlin silt loam, and Fuquay loamy sand, respectively. Degradation of 1,3-D resulted in the formation of cis- and trans-3-chloroallyl alcohol, cis- and trans-3-chloroacrylic acid, numerous minor carboxylic acid metabolites, and carbon dioxide. In addition, there was also extensive incorporation of {sup 14}C labeled material into the soil organic matter of both soils.
