Description

Weeding composition containing penoxsulam, pyraclonil and butachlor
Technical Field
The invention belongs to the field of pesticide chemistry, and particularly relates to a weeding composition for solving the problem of preventing and removing annual weeds in a rice field.
Background
Penoxsulam belongs to triazolopyrimidine sulfonamide herbicides and is an acetolactate synthase inhibitor. Penoxsulam can be absorbed by stem leaves, buds and root systems and is conducted to meristematic tissues through xylem and phloem to inhibit plant growth and lead the plants to die. Is suitable for direct seeding dry land, direct seeding water land, seedling field, seedling throwing field and seedling transplanting field. The application method can be spraying or soil mixing treatment. Penoxsulam is a broad-spectrum herbicide for rice fields, can effectively prevent and kill barnyard grass, moleplant seed and annual cyperaceae weeds, and is effective on a plurality of broadleaf weeds.
Pyraclonil belongs to a novel dipyrazole paddy field herbicide, is an inhibitor of protoporphyrinogen oxidase, and is a contact herbicide. The pyraclonil can effectively prevent and kill various weeds including barnyard grass, cyperus heterophyllus, arrowhead, monochoria vaginalis and the like.
Butachlor is a selective preemergence herbicide and is mainly used for preventing and killing annual gramineous weeds and certain broadleaf weeds in direct seeding or transplanting fields. The herbicide is an important variety of rice field herbicide, and is generally used for treating the soil surface before germination and can also be applied after seedling in a paddy field. Butachlor is absorbed by young sprouts and young secondary roots of weeds to inhibit the synthesis of protein, so that the weeds die. The herbicide composition is mainly used for preventing and killing annual gramineous weeds, annual cyperaceae weeds and certain annual broadleaf weeds in rice fields, and can also be used for preventing and killing weeds in barley, wheat, cotton and peanut crop fields.
The herbicide variety containing a single active component has defects of different degrees in weed control, and after continuous use, weeds are easy to generate drug resistance, so that the problems of narrow weed control spectrum, environmental pollution and the like occur. The reasonable compounding of the herbicide is an effective method for improving the preventing and killing effect, expanding the weed control spectrum, delaying the drug resistance of weeds, reducing the environmental pollution, reducing the use cost and reducing the herbicide residue.
Through searching for the patent containing penoxsulam, pyraclonil or penoxsulam, butachlor or pyraclonil and butachlor in a mixed mode, the patent or report aiming at the ternary mixed mode of penoxsulam, pyraclonil and butachlor is not disclosed temporarily.
