Problems solved by technology

In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance
At the same time, due to the complexity and variety of weeds when weeds occur, the use of a single species can no longer effectively solve the weeds in the farmland, and all of them will show some defects.
At present, there are many kinds of herbicides on the market, and the application technology is also demanding. If there is a little carelessness in the application, problems such as phytotoxicity and poor weeding effect will occur.

Abstract

The invention relates to a wheat field composite herbicide containing quinmerac and tribenuron-methyl. The herbicide is characterized in that the herbicide comprises main effective components A, B and C, wherein A is quinmerac, B is tribenuron-methyl, C is any one of clopyralid, aminopyralid, chipton, and carfentrazone-ethyl; the weight ratio of A:B:C is 1-150:1-20:0.1-50, the herbicide is used for wheat field post-emergence stem leaf treatment, and is used for control of broad-leaf weeds with substantial synergistic effects, such as Galium aparine, Veronica didyma, Shepherdspurse, Stellaria media, Stellaria uliginosa, and the like.

Description

[0001] Technical areas: [0002] The invention belongs to the technical field of pesticide compounding, and relates to a wheat field herbicidal composition containing quinclorac and bensulfuron, which is used for post-emergence stem and leaf treatment of wheat fields to control broadleaf weeds. [0003] technical background: [0004] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, due to the complexity and variety of grasses when weeds occur, the use of a single variety can no longer effectively solve weeds in farmland, and all will show certain deficiencies. There are many types of herbicides on the market today, and their application techniques are also demanding. If you are not careful during application, problems such as phytotoxicity and poor herbicidal effects may occur. Improper selection of herbicides wil...
