The choice of herbicide should be cautious, otherwise the consequences of improper use of phytotoxicity are very serious. China's pesticide network will share the skills of dry herbicide herbicide selection: quinclorac against valerian and rainy flowers, laps, and cress Broadleaf weeds such as ragweed and saponin have better control effects. For the control of alfalfa and broad-leaved weeds in rice dry-growing fields, a mixture of quinclorac and bensulfuron-methyl or pyrazosulfuron-methyl may be used. Due to the long-term application of quinclorac, some areas of valerian have a higher resistance to the drug, and the area with poor emulation should be replaced with penoxsulam (Taojie). Penoxsulam can effectively control a variety of broadleaf weeds such as yarrow and annual sedge and sedge, scorpion, bamboo grass, and ragweed.
