AI Technical Summary
There are several problems with weed control in rice paddies, including the separation of soil-applied and foliar applications, the inability to control both grasses and broadleaf weeds/sedges, short effective period, frequent application, and increasing weed resistance year by year. The market urgently needs an integrated herbicide that combines the dual functions of soil-applied and post-emergence foliar weed control, has a broad spectrum of weed control, a long effective period, high safety, and facilitates resistance management.
The ternary compound herbicidal composition of butachlor, bispyribac-sodium, and chlorpyrifos achieves dual herbicidal activity through differentiated and synergistic mechanisms of action, including soil sealing and post-emergence foliar application. It also features complementary herbicidal spectrum, significantly prolongs the effective period, reduces the number of applications, lowers the amount of pesticide used and labor costs, and improves the safety for rice.
It achieves excellent control efficacy against major annual weeds such as barnyard grass, Echinochloa crus-galli, duckweed, and Cyperus difformis in paddy fields, delays the evolution of resistant weeds, reduces the risk of herbicide damage, and meets the needs of green agricultural development.
