Description and Uses
Chlorthal-dimethyl is a selective benzoic acid herbicide. It has a low aqueous solubility and a low to moderate volatility. It is considered to be moderately persistent in soil systems but can be stable in aquatic systems depending upon conditions. Based on its physico-chemical properties it is not expected to leach to groundwater. Its toxicity to fauna and flora is low to medium. It also has a low mammalian toxicity and no evidence has been found that suggests it will cause serious adverse health effects unless exposure is high.
Selective, nonsystemic, preemergent herbicide to control most annual grasses and many broad-leaved weeds.
