Herbicide composition containing halauxifen-methyl and diflufenican

Abstract

The invention belongs to the technical field of farm chemical herbicides, and particularly relates to a herbicide composition containing halauxifen-methyl and diflufenican. The herbicide composition is suitable for wheat fields. The weight ratio of the active ingredient halauxifen-methyl to the active ingredient diflufenican ranges from 1:1.6 to 1:100. According to the herbicide composition, the weed control spectrum is broadened, the control effect is enhanced, the situation that the herbicide resistance of weeds can be rapidly generated when weed control is performed with a single herbicide is avoided, generation of the herbicide resistance of weeds is retarded, the dosage is reduced, the use cost is lowered, and environmental pollution is relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides and herbicides, and in particular relates to a herbicide composition suitable for wheat fields containing haclopyrid and diflufenican. Background technique [0002] Wheat is one of the main food crops in my country. Its planting area and total output are second only to rice. The national planting area is more than 30 million hectares, about 450 million mu, accounting for 22%-30% of the country's cultivated land area, which is about 20%-27% of the area, the total wheat output is about 100 million tons, reaching 22% of the total grain output (Wu Mingrong et al., 2013, Pesticides). Wheat is the main commodity grain and strategic reserve grain variety in my country, and plays an important role in grain production, circulation and consumption. The development of wheat production is of great significance to the development of my country's national economy and people's lives. According to the national...

Problems solved by technology

For example, if the sulfonylurea herbicides tribenuron-methyl and bensulfuron-methyl are used too high or too late, they will cause phytotoxicity to subsequent crops such as peanuts and soybeans.

Phenoxycarboxylic acid herbicides 2,4-D-Butyl Ester, Dimethyltetrachloride Sodium Salt Excessive dosage and improper application can easily cause crop damage and drift, which can cause damage to nearby dicotyledonous crops

[0004] Long-term use of single herbicide control will lead to a decrease in the number of sensitive weeds, and an increase in the number of insensitive or malignant weeds, causing changes in the weed community

In the winter wheat producing areas where herbicides are used alone, the weed community in the wheat field has undergone serious changes. The number of malignant weeds that are difficult to control with various herbicides, such as pigtails, lacquer, mother-in-law, and shepherd's purse, has increased year by year, and has seriously affected the Harvest of wheat crop yield
