Quinclorac
Quinclorac (CAS No.84087-01-4) can be 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.
Quinclorac Useage
Quinclorac is used for pre- and post-emergence controlling 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.
Quinclorac 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.
