ENVIRONMENTAL FATE
Animals:In rats, most of applied radioactivity is excreted rapidly, mainly within 24 h.Soil:Decomposed by microbial action; typical soil DT50 10-15 d. Koc 333.3 (acid, sandy soil), 364.4 (acid, loamy soil), 493.5 (alkaline, loamy soil).
Usage: Propisochlor is a pre-emergence or pre-plant herbicide for control of annual grasses and some broad leaved weeds.
Application: Biochemistry: Protein synthesis inhibitor. Mode of action: Selective herbicide, absorbed by the shoots of germinating plants. Uses: Pre-emergence or pre-plant incorporated for control of annual grasses and some broad-leaved weeds in maize, sunflowers, soya beans, potatoes and peas (1.1-1.8 kg/ha). It can be used in beans and sweet lupins (1.1-1.8 kg/ha) and onions (1.4-1.8 kg/ha).
