Active ingredient | Quinclorac | ||
Chemical name | 3,7-dichloro-8-quinolinecarboxylic acid | ||
Classification | Herbicide / Agrochemical | ||
Biochemistry | Synthetic auxin (acting like indolylacetic acid); also inhibitor of cell wall (cellulose) biosynthesis. | ||
Mode of action | Rapidly absorbed through the foliage. Weak auxin activity as determined in wheat coleoptile elongation test, cucumber root elongation test, cucumber curvature test and ethylene biosynthesis test in soya beans. No influence on Hill reaction. Plant response is similar to IAA or auxin-type herbicides of the class of benzoic acids and pyridine compounds. | ||
Usage | Pre- and post-emergence control of grass weeds (Echinochloa spp., Aeschynomene spp., Sesbania spp.) and other weeds in direct-seeded and transplanted rice, at 0.25-0.75 kg/ha. Phytotoxicity Non-phytotoxic to transplanted and direct-seeded rice. Under continuous irrigation conditions, injury may occur in adjacent umbelliferous crops if connected to the same waterway. | ||
Mammalian Toxicology | Oral Acute oral LD50 for rats 2680, mice >5000 mg/kg. Skin and eye Acute percutaneous LD50 for rats >2000 mg/kg. Non-irritating to eyes and skin (rabbits). Inhalation LC50 (4 h) for rats >5.2 mg/l. | ||
