WHO Classification: II (Moderately hazardous)

EC Risk Classification: Carcinogen category 3: R40; N - Dangerous for the environment: R50, R53       

US EPA Classification (formulation): No consensus across products or no products available

ECOTOXICOLOGY

Effect on birds: Acute oral LD50 for Bobwhite quail is 1401 mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is 37 mg/l. Effects on aquatic invertebrates:  Chronic 21 day NOEC for Daphnia magna is 0.12 mg/l. Effects on algae: Acute 72 hour EC50 for Navicula pelliculosa is 0.013 mg/l. Effects on bees: contact acute 48 hour LD50 is 200 μg/bee, oral acute 48 hour LD50 is 195 μg/bee. Effects on earthworms: Acute 14 day LC50 is >1000 mg/kg.   

ENVIRONMENTAL FATE

Animals In rats, following oral administration, 50% is eliminated within the first 8 h, predominantly in the urine. Plants In plants, degradation is mainly via hydroxylation of the isopropyl group to 1,1-dimethyl-3-[4-(2'-hydroxy-2'-propyl)phenyl]urea; N-dealkylation also occurs. Soil/Environment Undergoes enzymic and microbial demethylation at the nitrogen, and hydrolysis of the phenylurea to 4-isopropylaniline. DT50 in soil 6-28 d; rate of degradation increases 3x between 10 and 30(sandy soil) and 10x in an organic soil over the same temperature range.  

Usage: Isoproturon was introduced by Ciba-Geigy AG (became Novartis Crop Protection AG). It is a herbicide for use, typically, in cereals to control annual grasses and many broad-leaved weeds.

Application: Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Mode of action Selective systemic herbicide, absorbed by the roots and leaves, with translocation. Uses Pre- and post-emergence control of annual grasses (Alopecurus myosuroides, Apera spica-venti, Avena fatua and Poa annua) and many annual broad-leaved weeds in spring and winter wheat (except durum wheat), spring and winter barley, winter rye, and triticale, at 1.0-1.5 kg/ha.
