Mixed herbicide containing flazasulfuron and dithiopyr

Abstract

The invention discloses a mixed herbicide containing flazasulfuron and dithiopyr. The herbicide takes flazasulfuron and dithiopyr as the main effective components, and flazasulfuron and dithiopyr are in a mass ratio of 0.1-80:0.1-80. The mixed herbicide provided by the invention has significant application effect in lawn weeding, especially in control and elimination of various Gramineae, cyperaceae and broadleaf weed in lawn. Relative to a single agent, under the premise of improving the efficacy, the herbicide provided by the invention delays the weed resistance and has wide weeding spectrum, long duration and safety to lawn.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and relates to a herbicide, in particular to a binary mixed compound of rimsulfuron-methyl and dithiopyr. The herbicide composition can be applied to lawn weeding before or after emergence . Background technique

[0002] With the acceleration of my country's urbanization process, the improvement of urban greening standards and the substantial growth of urban areas, various lawns have emerged as the times require, which has triggered a huge demand for lawns, and the development of the lawn industry has good business opportunities. Lawns are important auxiliary facilities in terms of ensuring the solidity and beauty of infrastructure such as roads, railways, airports, reservoirs, river banks, and lake embankments; in terms of urban construction and landscaping, lawns can greatly improve the living environment and effectively reduce the city's "heat island" effect". The area and quality of lawn...
