Dacthal is used as a preemergent herbicide.
Verwenden
Pre-emergent herbicide.
Definition
ChEBI: Dacthal is a diester and a methyl ester.
mögliche Exposition
DCPA is an alkyl phthalate; benzene- dicarboxylic acid herbicide, pesticide pre-emergent herbi- cide is used on annual broadleaf weeds and grasses in a wide spectrum of vegetable crops.
Environmental Fate
Soil. Bartha and Pramer (1967) reported that DCPA was degraded by soil microorganisms via cleavage of the herbicide molecule into propionic acid and 3,4-dichloroaniline. The acid was mineralized to carbon dioxide and water and two molecules of 3,4-dichloroaniline were condensed to form 3,3′4,4′-tetrachloro-azobenzene. Metabolites identified in soil and turfgrass thatch are monomethyl tetrachloroterephthalate and 2,3,5,6-tetrachloroterephthalic acid (Hartley and Kidd, 1987; Krause and Niemczyk, 1990). Residual activity in soil and the half-life in soil were reported to be approximately 3 months (Hartley and Kidd, 1987; Worthing and Hance, 1991)
