Problems solved by technology

Temperature has no effect on the final effect of weeding, but affects the speed of its efficacy
Generally, when the temperature is low, the drug effect is slow, and the plant will stop growing after poisoning, but it will not die immediately; the plant will die soon after the temperature rises.

Abstract

The invention provides a herbicide composition. The herbicide composition comprises a fluroxypyr derivative, mesotrione and a sulfonylurea compound, wherein the weight part ratio of the fluroxypyr derivative to the mesotrione to the sulfonylurea compound is 0.1-5:0.1-10:0.1-10. The composition can be prepared into emulsifiable concentrate, liquor, aqua, dense emulsion, microemulsion, wettable powder, water suspension, oil suspension, water dispersible granules or soluble powder (granules). The herbicide composition of the invention can be used for preventing and controlling annual and perennial grasses and broadleaves.

Description

technical field [0001] The present invention relates to an agricultural herbicide, more specifically to a herbicide composition containing fluroxypyr derivatives, mesotrione and sulfonylurea compounds and application thereof. Background technique [0002] Fluroxypyr is a post-emergence herbicide of pyridine systemic conduction type. After the drug is quickly absorbed by the plants, the sensitive plants will respond to typical hormone herbicides, and the plants will be deformed and twisted. In drug-resistant plants such as wheat, fluroxyrpyr can be combined into conjugates to lose toxicity and thus have selectivity. Temperature has no effect on the final effect of its weeding, but affects the speed of its efficacy. Generally, when the temperature is low, the drug effect is slow, which can stop the growth of the plant after poisoning, but it does not die immediately; the plant dies soon after the temperature rises. The leaching in the soil is not significant, and most of th...
