Herbicide composition containing flazasulfuron and use of herbicide composition

Abstract

The invention discloses a herbicide composition containing flazasulfuron and use of the herbicide composition. The herbicide composition comprises the following components by weight percent: 1-30% of an active component A, 1-30% of an active component B, 1-5% of a dispersant, 1-5% of a wetting agent, 1-5% of an adhesive and the balance being filler or deionized water, wherein the active component A is flazasulfuron. The herbicide composition containing the flazasulfuron disclosed by the invention can be applied to effective prevention and removal of annual grasses and broad leaf weeds of direct-seeding rice fields and seedling slinging fields, such as barnyard grass, leptochloa chinensis, crab grass, paspalum distichum, false loosestrife, sheathed monochoria herbs, pondweeds and the like, so as to play a synergistic effect. The herbicide composition has a good weeding effect, not only is the control effect improved by use in a form of a composition, but also the use cost is reduced, and the utilization rate of effective ingredients is improved.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a herbicide composition containing sulfasulfuron-methyl and its application. Background technique [0002] Rice is one of the most important food crops in the world and also one of the most important food sources in my country. There are many important factors that endanger the yield of rice. In addition to the factors of diseases and insect pests, weeds are also an important factor. Weeds are non-target cultivated plants in farmland. The main hazard is that weeds will compete with crops for water, fertilizer, light and space. At the same time, it is also the intermediate host of crop diseases and insect pests. The area of ​​rice weed damage is high in our country, so weeds must be controlled to increase the yield of wheat. [0003] In recent years, the rational selection of rice herbicides has become an important technical link to ensure the safety of rice producti...

AI Technical Summary

Problems solved by technology

[0003] In recent years, the rational selection of rice herbicides has become an important technical link to ensure the safety of rice production. However, due to improper selection of herbicides or inadequate use of technology, the control effect will be unsatisfactory or cause critical problems.

At present, there are few herbicide varieties that can control grass weeds and broadleaf weeds at the same time. Usually, after people use a certain herbicide to control grass weeds, broadleaf weeds become the dominant population of weeds; or Yes, after removing the broad-leaved weeds, grass weeds have become the dominant population of weeds again, and the weeding effect is poor due to the waste of manpower
