Herbicide composition and application thereof

Abstract

The invention provides a herbicide composition, comprising the following active ingredients by weight: 0.1-5 parts of mesotrione, 0.1-10 parts of fluroxypyr and 0.1-10 parts of diflufenzopyr. The invention also provides application of the herbicide composition to controlling annual and perennial broadleaf weeds and grass weeds in the corn fields. The herbicide composition obviously improves the weed control effect compared with the single agent, has excellent synergy, reduces the drug dosage, reduces the impact on the environment while lowering the drug cost of the farmers, simultaneously expands the weed control spectrum and can effectively retard occurrence and development of the tolerance of the single angle.

Description

technical field

[0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide composition containing three active ingredients: mesotrione, fluroxypyr and flufenpyr and its application. Background technique

[0002] Mesotrione is a broad-spectrum herbicide that can be used both before and after emergence. It is a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor and a triketone herbicide developed by Zeneca. , can effectively control annual grass weeds and most broad-leaved weeds, especially for weeds resistant to sulfonylurea herbicides.

[0003] Fluroxypyr is a systemic conduction herbicide, which is quickly absorbed by plants after application, causing sensitive plants to respond to typical hormone herbicides, resulting in deformed and distorted plants. 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, and the plant w...
