It is a selective contact-type post-emergence herbicide for weed stem and leaf treatment. It is mainly used in rice, soybean, peanut, wheat and other crops to control broadleaf weeds and sedge weeds, and is ineffective against grass weeds.
The mechanism of action of bentazone:
It is mainly absorbed by the leaves (the root system can also be absorbed in the paddy field), and is transmitted to the chloroplast through the leaf surface to inhibit the photosynthesis electron transfer. The two-dimensional absorption and assimilation process of the chemical cooperation process was inhibited 2 hours after application; all of them stopped at 11 hours, and the leaves wilted and turned yellow, eventually leading to death. Some crops can metabolize the herbicide to rapidly degrade into inactive substances.
Control object and method
1. Paddy fields: water live fields, transplanted fields can be used. The control of weeds and broadleaf weeds is significant and is not effective against alfalfa.
2. Wheat field: stem and leaf spray to control broad-leaved weeds such as piglet, Maijiagong and other wheat fields.
3. Peanut field: Control broadleaf grass and sedge of Xanthium, Poria, Purslane, and oil sedge.
3. Soybean field: sprayed with a sprayer for stem and leaf treatment, can prevent weeds such as broadleaf weeds and broken rice sedges such as cockroaches, cockroaches, cockroaches, pig's head, piglets, and nest vegetables. .
