Problems solved by technology

[0017] At present, lawn herbicides are limited by safety and herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of lawn weeds. Moreover, some herbicides are too water-soluble or have too long a field duration. 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 flumetsulam. The herbicide takes flazasulfuron, dithiopyr and flumetsulam as main active ingredients, wherein the mass ratio of flazasulfuron to dithiopyr to flumetsulam is (0.1-80): (0.1-80): (0.1-80). The mixed herbicide disclosed by the invention can be applied to weeding before and after seedling emergence of a lawn, and particularly has significant effects when being applied to control of various gramineae, cyperaceae and broadleaf weeds in the lawn. The mixed herbicide disclosed by the invention has relatively high synergy, delayed weed resistance, broad herbicidal spectrum and long lasting period; and furthermore, the mixed herbicide is safe to the lawn, and the effect is obviously higher than that of a single agent.

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 flumesulfame, and 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"...
