Bentazone is a herbicide marketed by BASF in 1972, and the current global demand is about 9000 tons. With the ban of 2,4-drops in Vietnam, the combination of methamphetamine and oxazolamide is expected to have good application prospects in local rice crops. Will this old variety, which is nearly half a century old, revitalize the Southeast Asian market?
Product Introduction
Chemical name: 3-isopropyl-1H-2,1,3-benzothiazide-4 (3H) - ketone 2,2-dioxide, commonly known as bentazone; Other names: Bendazone, Paicao Dan. Its structural formula is as follows.
Mechanism of action: Fencao pine is a contact killing and selective post seedling herbicide, which is used in dry fields and is transmitted into chloroplasts through leaf infiltration to inhibit photosynthesis. Soybeans can metabolize methamphetamine, causing it to degrade into active substances. However, sensitive plants are inhibited in the process of carbon dioxide assimilation after application, until all stop, and their leaves wilt and turn yellow, ultimately leading to death. A sunny and warm climate is conducive to the effectiveness of medication. When used in paddy fields, it can penetrate through the leaves and absorb through the roots, which is transmitted to the stems and leaves, strongly inhibiting weed photosynthesis and water metabolism, causing nutritional starvation and physiological dysfunction leading to death.
Control objects: It can control a variety of broad-leaved weeds and Cyperaceae weeds, and can be used for weeding in soybean, corn, pea, and rice fields, such as theophrasti theophrasti, shepherd's purse, water chestnut, spindless Datura, Helianthus, polygonum, Portulaca, Ragweed, Xanthium, heterotypic sedge, duck tongue grass (the effect is good in the first to second leaf period, and the effect is significantly reduced in the third leaf period), melon skin grass, sparganium, etc. It can also be used for winter control Anthemis, Matricaria, pearl chrysanthemum, and swine bane in the field of spring cereal crops.
