Wheat field herbicide composition containing clodinafop-propargyl

Abstract

The invention discloses a wheat field herbicide composition containing clodinafop-propargyl. The active ingredients of the herbicide composition consist of mesosulfuron, the clodinafop-propargyl and florasulam, wherein the mass ratio of the mesosulfuron to the clodinafop-propargyl to the florasulam is (1-10) to (15-72) to (0.5-12). The herbicide composition has a certain control effect on broadleaf weeds and grassy weeds in a wheat field, and the highest decrease rate and the highest control rate can be 100 percent after 30-day drug administration.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a wheat field herbicide composition containing clodinafop-propargyl. Background technique [0002] According to the national weed census data report, there are more than 200 kinds of weeds in wheat fields in my country, and the area of ​​weed damage accounts for more than 30% of the wheat planting area, and the loss accounts for about 15% of the total wheat output, reaching 10 billion kilograms. Swine worms, Artemisia persicae, and Dachao are serious hazards. However, with the long-term and large-scale application of herbicides, the problems of weed resistance, population succession and phytotoxicity in chemical weed control in farmland are becoming more and more serious, seriously affecting the high yield and harvest of wheat and the safety of subsequent crops. At present, there are some disadvantages in commonly used medicaments in wheat fields. For ex...

AI Technical Summary

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

In addition, if a single herbicide is used for long-term control, the number of sensitive weeds will decrease, and the number of insensitive or malignant weeds will increase, 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
