ENVIRONMENTAL FATE

Animals The major metabolic pathway for propanil in microsomal incubations was acylamidase hydrolysis to 3,4-dichloroaniline (D. C. McMillan et al., Tox. Appl. Toxicol., 1990, 103, 90). Plants In rice, propanil is hydrolysed by an aryl acylamidase to 3,4-dichloroaniline and propionic acid as metabolic intermediates. Soil/Environment In soil, rapid microbial degradation to the aniline derivative occurs. Duration of activity in warm, moist conditions is only a few days. Degradation products are propionate which is rapidly metabolised to CO2, and 3,4-dichloroaniline which is bound (80% in 27 h) to the soil. Koc 239-800.   

Usage: Propanil was introduced by Rohm & Haas Co. (now Dow AgroSciences). Propanil is a post-emergence herbicide used for broad-leaved and annual grass weed control in rice and other crops.

Application: Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Mode of action Selective contact herbicide with a short duration of activity. Uses Contact herbicide used post-emergence in rice, at 2.5-5.0 kg/ha, to control broad-leaved and grass weeds, including Amaranthus retroflexus,Digitaria spp., Echinochloa spp., Panicum spp., and Setaria spp. Also used, in mixture with MCPA, in wheat. A mixture with carbaryl is used in citrus crops grown in sod culture. Phytotoxicity Phytotoxic to many broad-leaved crops. Normally phytotoxic to crops which have been treated with organophosphate or carbamate insecticides.
