#Agricultural Technology Science Competition #At present, it is the period of rice planting, and large areas of rice planting have begun. The first problem after planting is weeding. Benzothiamol is a common systemic conduction-blocking herbicide. It can effectively control grass weeds, has a special effect on barnyard grass in the germination to 2-leaf stage, and also has a certain anti-effect on thousand gold, cow felt, lacquer, duck tongue grass, knotweed, special-shaped sedge, flat sedge, broken rice sedge and perennial aquatic sedge.
