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, carfentrazone-ethyl and dithiopyr as well as applications thereof. Flazasulfuron, carfentrazone-ethyl and dithiopyr are used as main effective components, and the mass ratio of flazasulfuron, carfentrazone-ethyl and dithiopyr is 0.1-80:0.1-80:0.1-80. The application of the mixed herbicide to weeding in lawn, especially applications to controls of Gramineae weeds, Cyperaceae weeds and broad-leaf weeds in lawn have substantial effects. Compared with a mono-agent, the herbicide has improved drug effects, and has the advantages of delayed weed resistance, wide weeding spectrum, long persistent period, and safety for lawn.

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, pyrentrazone-ethyl and dithiopyr, the herbicide composition can be applied to lawn pre-emergence , Post-emergence weeding. 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".
