Problems solved by technology

[0005] Flufenacet is an oxyacetanilide herbicide developed by Bayer Company of Germany. It mainly acts by inhibiting cell division and growth. It has the characteristics of high herbicidal activity, wide herbicidal spectrum, wide range of applicable crops, and high safety. It has good control effect on perennial grass weeds, such as kangaroo and bluegrass; it is ineffective on some broad-leaved weeds such as amaranth and commelina, but it is ineffective against Abutilon and Solanum nigrum

Abstract

The invention belongs to the technical field of pesticides, and discloses a wheat herbicidal composition, with saflufenacil, isoproturon and flufenacet as main active ingredients, and saflufenacil, isoproturon and flufenacet The mass ratio of the three is 5-40:0.1-10:3-45, and the mass percentage of the sum of the three in the herbicidal composition is 10-80%. The invention also discloses that the herbicidal composition can be prepared into wettable powder, water dispersible granule and water suspension, and can be used for controlling grass and broadleaf weeds in wheat fields. The herbicidal composition of the invention has the characteristics of wide herbicidal spectrum, low control cost, wide herbicidal spectrum, good drug effect, excellent long-lasting effect and little environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide for wheat fields, in particular to a herbicidal composition containing saflufenacil, isoproturon and flufenacet and an application thereof. Background technique [0002] Weeds in wheat fields directly affect the yield of wheat crops and are the key factors restricting the yield of crops. Controlling weeds in wheat fields is an important task in the development of wheat production. The use of chemical herbicides is one of the important symbols of modern agriculture. At present, weed control in wheat fields is mainly based on post-emergence aryloxyphenoxypropionate herbicide stem and leaf spraying. Although there are a variety of herbicide varieties available for different stages, most of them are difficult to guarantee a one-time application to keep the crops free of weeds throughout the growth period. Therefore, from an economic and environmental point of view, it ...
