Activity
Propanil is an acetanilide post-emergence herbicide with no residual effect. It is used against numerous grasses and broad-leaved weeds. It is available as emulsifiable concentrates, liquid and dry flowable, low volume, and ultra low volume (ULV) formulations. Mixing with carbamates or organophosphorans compounds is not recommended. The information presented here, unless otherwise noted, pertains to technical propanil.

Toxicology
Oral:Acute oral LD50 for rats >2500, mice c. 1800 mg/ kg. Percutaneous:Acute percutaneous LD50 (24 h) for rats >5000 mg/kg. Not irritating to skin and eyes (rabbits). Not a skin sensitiser (guinea pigs). Inhalation: LC50 (4 h) for rats >1.25 mg/l air (dust). Phytotoxicity:Phytotoxic to many broad-leaved crops. Normally phytotoxic to crops which have been treated with organophosphate or carbamate insecticides.
Environmental Profile
Ecotoxicology: 
Birds:Acute oral LD50 for mallard ducks 375, bobwhite quail 196 mg/kg. Dietary LC50 (5 d) for mallard ducks 5627, bobwhite quail 2861 ppmDaphnia: LC50 (48 h) 4.8 mg/l.Fish: LC50 (48 h) for carp 8-11 mg/l. 

Environmental fate: 
Animals:The major metabolic pathway for propanil in microsomal incubations was acylamidase hydrolysis to 3,4-dichloroaniline (D. C. McMillan , 1990, 103, 90).Soil: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 Plant:In rice, propanil is hydrolysed by an aryl acylamidase to 3,4-dichloroaniline and propionic acid as metabolic intermediates. SOIL PARTICLE ADSORPTION: Moderate WATER SOLUBILITY: Sparingly soluble, 0.13 g/l at 25°C HAZARDS: Fish: LC50 14 ppm (bluegill); 13 ppm (rainbow trout). Bird: Dietary LC50 2861 ppm (bobwhite quail), 5627ppm (mallard); Oral LD50 201 mg/kg (quail) DEGRADATION/METABOLISM: Half-life in soil 1.5 days
