Abstract

The invention belongs to the technical field of a pesticide, and discloses a herbicide composition. Bicyclopyrone and pendimethalin are used as major active ingredients; the mass ratio of the bicyclopyrone to the pendimethalin is (1 to 40): (1 to 40); the mass percentage of the sum of the bicyclopyrone and the pendimethalin in the herbicide composition is 2 to 80 percent. The invention also discloses wettable powder, water dispersible granules, missible oil and water suspension capable of being prepared from the herbicide composition. The advantages of wide weeding spectrum, good prevention efficacy effect, good durable effect and good quick-acting effect are realized; the herbicide composition can be used for preventing and removing corn field weed.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition for controlling annual weeds in cornfields with synergistic synergistic effect of dual compound of flufenazol and pendimethalin. Background technique [0002] Herbicide varieties containing a single active component often have different degrees of defects in the control of weeds in agricultural fields. For example, weeds are prone to resistance after continuous application, the herbicide spectrum is narrow, and frequent applications will aggravate environmental pollution. For the prevention and control of resistant weeds produced in agriculture, one way is to introduce new ingredients that have no cross-resistance with existing varieties, but the development cost of new active ingredients is high, the development cycle is long, and it will never keep up with it. The rate at which weeds develop resistance. Other methods, such as crop layout...
