Problems solved by technology

Among the existing herbicides, a variety of herbicidal compounds are often used in combination to increase the range of weeding, but it is very easy to have the problem of excessive drug dosage and high pesticide residues in plants and soil
When only flubisulfuron-methyl and cyhalofop-ethyl are mixed, there are problems of narrow weeding range and many auxiliary materials added

Abstract

The invention belongs to the technical field of agricultural herbicides, and particularly relates to a weeding composition containing flucetosulfuron and cyhalofop-butyl/penoxsulam/metamifop, and a preparation method thereof. Aiming at the problems of narrow weeding range and many auxiliary materials of the existing rice herbicide, the invention provides the weeding composition which is composed of at least one of flucetosulfuron, cyhalofop-butyl, penoxsulam or metamifop. Flucetosulfuron and cyhalofop-butyl/penoxsulam/metamifop are particularly screened to be mixed and used according to a certain ratio, and a remarkable synergistic interaction effect can be achieved. Under the combined use condition, the weeding speed is high, the lasting period is long, the application cost is reduced, and the prevention and treatment effect is obviously better than that of a single agent. The weeding composition is advanced in dosage form, high in activity, better in mixed pesticide effect and more uniform in mixing, the weeding effect is obviously improved, and the weeding composition has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and in particular relates to a herbicidal composition containing flubisulfuron-methyl and cyhalofop-methyl / penoxsulam / oxentrafen and a preparation method thereof. Background technique [0002] Flubisulfuron-methyl is a new type of sulfonylurea herbicide developed by Korea LG Life Science Co., Ltd. It is an inhibitor of acetolactate synthase, that is, by inhibiting the ALS enzyme of plants, it prevents the biosynthesis of branched-chain amino acids and ultimately destroys Protein synthesis, interference with DNA synthesis and cell division and growth. The preparation has a wide herbicidal spectrum, is highly effective against barnyard grass, and has a significant control effect on grasses, such as bermudagrass and weeds. [0003] Cyhalofop-ethyl is an aryloxyphenoxypropionic acid herbicide. It is a selective herbicide for paddy fields. It can only be used for stem and leaf treatme...
