Abstract
The invention relates to the technical field of production of pesticides and discloses a weeding composition containing flufenacet and fenoxasulfone. The composition contains two active components including flufenacet and fenoxasulfone; auxiliary materials including a wetting agent, a dispersant, a thickening agent, a stabilizer, an anti-freezing agent, a de-foaming agent and the like are added into the two active components and all the materials are mixed with water; and the composition is obtained by preparing the mixture into a suspending agent through high-speed shearing, wet sanding, and homogenization and filtering. The weight ratio of flufenacet to fenoxasulfone is 1 to (0.5-2); and the weight percent of the two effective components in the composition is 10%-60%. After the two active components including flufenacet and fenoxasulfone are compounded, the disadvantage of the single component is made up; and the weeding composition has a remarkable synergistic effect and good safety, and is an ideal weeding composition.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of Herbicidal combinations with the property improved, relate in particular toA kind of Herbicidal combinations that contains flufenacet and sulfone pyrrole grass azoles.
Background technology
Farmland weed damage to crops, brings about great losses to agricultural production. According to statistics, world's farmland weedHave kind more than 1000, what causing harm property was larger has more than 90 to plant, and because crop smothering makes the average underproduction 10% in farmland, chemistry removesGrass becomes the important means of agricultural development. The exploitation of herbicide is faced with environmental protection pressure and green foodThe double challenge that product need, " efficient, low toxicity, safely " becomes the new theme of herbicide initiative.
How to seek one efficient, easy to use, environmentally safe, to crop and succession crop peaceThe direction of our research of full herbicide.
Summary of the invention
In order to comply with the new theme of above-mentioned herbicide innovation, the present invention has designed one and has contained flufenacetWith the Herbicidal combinations of sulfone pyrrole grass azoles, by two kinds of efficient, safe novel herbicidal composition flufenacets andSulfone pyrrole grass azoles is composite, can prevent and kill off grassy weed can prevent and kill off again broad-leaved in the auxiliary agent formation that is equipped with otherWeeds, easy to use, environmentally safe, to the herbicide of crop and succession crop safety.
The technical solution used in the present invention is: a kind of Herbicidal combination that contains flufenacet and sulfone pyrrole grass azolesThing, the component that contains following percentage by weight relation in this Herbicidal combinations:
The weight ratio of above-mentioned flufenacet and sulfone pyrrole grass azoles is 1:(0.5-2).
