Compound herbicide composition for wheat field

Abstract

The invention relates to an herbicide for a farmland, especially to a compound herbicide composition for a wheat field, and belongs to the technical field of pesticides. According to the technical scheme adopted in the invention, the compound herbicide composition for a wheat field is characterized in that it contains effective components of bensulfuron methyl, tribenuron-methyl and flucarbazone-sodium and the weight ratio of the effective components is 1-10:1-8:1-9. The invention has the following beneficial effects: the compound herbicide composition has wide weed control spectrum, can be used to control and remove weeds in the field, has high security for crops, contains low toxicity, is less toxic to crops, human and animals, can be safely control and remove weeds without damaging crops, and has a significant effect of controlling and removing weeds.

Description

technical field [0001] The invention relates to farmland herbicides, in particular to a compound herbicide composition for wheat fields, which belongs to the technical field of pesticides. Background technique [0002] The damage of weeds to crops will reduce crop yields, so a large amount of herbicides need to be applied every year to control weeds to reduce losses. In recent years, the harm of weeds in wheat fields has become more and more serious, and due to the excessive use of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year. At present, the most important herbicide varieties in wheat fields are single-dose tribenuron-methyl, single-dose tribenuron-methyl or single-dose flucarbazone-methyl, which cannot completely remove weeds in wheat fields. Due to the continuous use of tribenuron-methyl single agent for many years, the resistance to pig scorpion in various regions and other broad-lea...

AI Technical Summary

Problems solved by technology

In recent years, the harm of weeds in wheat fields has become more and more serious, and due to the excessive use of herbicides, weeds have become more and more resistant to pesticides, resulting in a decrease in the weed control effect year by year

At present, the most important herbicide varieties in wheat fields are trisulfuron-methyl single-dose, tribenuron-methyl single-dose or flucarbazone-methyl single-dose, which cannot completely remove weeds in wheat fields

Due to the continuous use of tribenuron-methyl single agent for many years, the resistance to pig scorpion in various regions and other broad-leaved weeds have gradually transformed from weak grasses to strong grasses; the commonly used herbicide tribenuron-methyl can only control wheat fields Broad-leaved weeds have no control effect on gramineous weeds; fenoxaprop-ethyl can only control gramineous weeds but has no control effect on broad-leaved weeds; therefore, there is a need for herbicide varieties with better herbicidal effects
