Chemical herbicides have strong killing power against weeds when the temperature is above 20 °C. Generally, after 15 days of rice transplanting, the application of herbicides is very good after 6-7 days of medium and late rice planting. The specific requirements are to choose dry sun dew after drying. For the field of valerian, 60-70 ml of 10% gold emulsifiable concentrate can be used, and 20-30 kg of water can be sprayed. After 5-7 days, all valerian will die. There are also some malignant weeds, such as striated grass, wild sage mushroom, and squamous grass, which can be used in rice field transplanting or live broadcast. When it grows 3-5 leaves, 2.5% rice syrup suspension can be added with herbs. Dry or rushing grass, add moist soil to form toxic soil, keep 3-5 cm water layer for 7-8 days, or use 40 grams of turfgrass plus 70% dimethyl tetrachloride, mix with wet 15 kg of soil can be applied evenly to kill a variety of weeds.
