ApplicationBispyribac-sodium is a broad-spectrum herbicide that controls annual and perennial grasses, broadleaf weeds and sedges. It has a wide window of application and can be used from the 1-7 leaf stages of Echinochloa spp; the recommended timing being the 3-4 leaf stage. The product is for foliar application. Flooding of the paddy field is recommended within 1-3 days of application. Following application, the weeds take approximately two weeks to die. Plants exhibit chlorosis and cessation of growth 3 to 5 days after application. This is followed by necrosis of terminal tissues.
Storage StabilityStable for 2 years after receipt of order if stored under recommended conditions. After 2 years, the compound should be re-analyzed for chemical purity before use.
