Abstract: | Abstract Degradation of the nematicide Telone II (cis‐ and trans‐1,3‐dichloropropene comprise the active ingredients) in soil was studied using 14C‐l,3‐dichloropropene (DCP) along with soil samples collected from a field test site near Quincy, Florida. A mixed bacterial culture isolated from the soil in the presence of a second carbon source, glucose or yeast extract, completely degraded 14C‐DCP to 14CO2, water‐soluble products, and microbial mass. 14C‐DCP in soil was also degraded to 14CO2. After 28 days of incubation, the labeled chemical was completely degraded to 14CO2, water‐soluble metabolites, bound‐residues, and possibly some microbial mass. Little or no difference was observed in the degradation of 14C‐DCP in soil samples collected one week prior to field application of Telone II, or two weeks and two years after application. |
