Problems solved by technology

[0016] At present, lawn herbicides are limited by safety and herbicidal spectrum is also limited. A single herbicide alone cannot completely and effectively control the occurrence of lawn weeds. Long-term use, excessive dosage or uneven application are likely to cause residual toxicity

Abstract

The invention discloses a mixed herbicide containing flazasulfuron, dithiopyr and pendimethalin. The herbicide is prepared by taking flazasulfuron, dithiopyr and pendimethalin as main effective components, wherein the mass ratio of flazasulfuron to dithiopyr to pendimethalin is (0.1-80):(0.1-80):(0.1-80). The mixed herbicide can be applied to weeding before seedling emergence of a lawn and is particularly remarkable in effect when being applied to prevention and control of various grass families, sedge families and broad leaf weeds in the lawn. The mixed herbicide is relatively high in synergistic effect, capable of delaying the weed resistance, wide in weeding spectrum, long in lasting period and safe to the lawn; and the effect of the mixed herbicide is remarkably higher than that of a single herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a herbicide, in particular to a ternary mixed compound of pyrimsulfuron-methyl, dithiopyr and pendimethalin. The herbicide composition can be applied to lawn seedlings Weeding before and 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". ...
