Pinoxaden containing herbicide composition and application thereof

Abstract

The invention relates to a herbicide composition. The herbicide composition is prepared from pinoxaden and sulfonylurea herbicide. The herbicide composition is compounded of pinoxaden and sulfonylurea herbicide of sodium iodosulfuron-methyl, monosulfuron ester or tribenuron-methyl, the pinoxaden and the sulfonylurea herbicide of sodium iodosulfuron-methyl, monosulfuron ester or tribenuron-methyl are compounded to achieve good synergistic interaction within a certain ratio range; compared with the single component, the mixed composition has the advantages that weed control effect is improved greatly, the using dose is reduced, the application cost of farmers is reduced and the adverse effect of pesticide on the ecological environment is reduced.

Description

technical field [0001] The invention involves the field of pesticide technology, which specifically involves a herbicide composition and its applications with azoline -containing grassy -containing. Background technique [0002] Wheat is one of the main crops in my country. The planting area and yield are second only to rice. It is both the main food resources and an important industrial raw material. It occupies an important position in the national economy. However, my country's mackerel fields have always occurred to varying degrees of grass damage. The damage rate of weeds of wheat fields is about 75 %, which is about 15 % of production and a maximum of 80 %. It is an important factor affecting the quality and output of wheat. With the changes in the planting system and cultivation management in recent years, some new weed types and some non -farmland malignant weeds have developed rapidly in wheat fields, and new weed communities have formed. The single continuous use ...

[0010] Monosulfuron-ester (Monosulfuron-ester), chemical name: N-[2'-(4'-methyl)pyrimidinyl]-2-methylcarboxylate benzenesulfuronyl urea, see formula IV above for the structural formula, monosulfuron-ester Ester is a new type of sulfonylurea herbicide with super efficient systemic conduction. It has the same mechanism of action as other sulfonylurea herbicides and is an acetolactate synthase (ALS) inhibitor. It can be used for winter and spring wheat fields to control fields Annual and perennial broad-leaved weeds such as quinoa, succulents, and Artemisia argyi have very good control effects. As a super-efficient creative pesticide with independent intellectual property rights in my country, monosulfuronate has a small amount of ultra-high efficiency, slight toxicity, and medicinal properties. It has the characteristics of stable efficacy, environmental friendliness, and moderate application cost. The disadvantage is that it is ineffective against grass weeds in the field.

[0015] CN201310737771.4 discloses a herbicidal composition containing flucarbasulfuron-methyl and monosulfuron-methyl. Both components belong to sulfonylurea herbicides and have the same mechanism of action. The same mechanism of action is used to kill weeds, which is easy to use Weeds are resistant to it
