Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a herbicide composition suitable for a corn field and a sugarcane field, and a preparation method and application thereof.
Background
The herbicide reduces the labor capacity of people to a certain extent, and in recent years, the herbicide is widely used in corn fields and sugarcane fields in China.
However, the herbicide toxicity phenomenon of corn appears in different degrees every year, and particularly, the phenomenon is in an increasing trend in the year, so that the yield of corn is reduced, and the phenomenon of no harvest can also appear seriously. Nicosulfuron, 2-methyl-4-chloro-sodium and acetochlor have been reported to be phytotoxic to corn. Therefore, one of the key factors for ensuring the safe planting of the planted corns is the scientific use of the herbicide.
The herbicide drug variety and dosage form for chemical weed control in the sugarcane field are seriously aged, vast sugarcane farmers use the same herbicide for weeding for a long time, the dosage of the sugarcane herbicide is increased very fast due to year-by-year increase of the resistance of the weeds, and herbicide products with the same components and different contents and proportions are continuously on the market, so that the ideal method for chemical weed control in the sugarcane field gradually loses the advantages, the weeds are bred, and the yield loss of the sugarcane is huge. Moreover, because the planting area of the high-yield and high-sugar sugarcane varieties is continuously expanded, the high-sugar sugarcane varieties are extremely sensitive to the current common herbicide products of the sugarcane, especially to the products containing 2-methyl-4-chlorophenoxyacetic acid, ametryn and diuron, and cannot be popularized and applied on the high-sugar sugarcane varieties. At present, no proper herbicide product exists for high-sugar sugarcane varieties.
