| Dacthal Chemical Properties |
| Dacthal Usage And Synthesis |
| Chemical Properties | Colorless crystalline | | Chemical Properties | Colorless to gray crystalline solid. Practically
odorless. | | Uses | Pre-emergent herbicide. | | Uses | Selective, nonsystemic, preemergent herbicide to control most annual grasses and
many broad-leaved weeds. | | Uses | Dacthal is used as a preemergent herbicide. | | Potential Exposure | 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) | | Shipping | UN3077 Environmentally hazardous substances,
