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 weedicide containing flazasulfuron, dithiopyr and pyributicarb. The mixed weedicide adopts flazasulfuron, dithiopyr and pyributicarb as main effective components, wherein the mass ratio of flazasulfuron to dithiopyr to pyributicarb is (0.1-80) to (0.1-80) to (0.1-80). The mixed weedicide can be applied to weeding in front of and behind lawn seedlings, particularly to prevention and removal of various grassy, cyperaceous and broad-leaved weeds in the lawn, and has a remarkable effect; in addition, the mixed weedicide has a relatively good synergetic effect, can delay the resistance of the weeds, and is wide in weeding spectrum, long in lasting time, safe to the lawn and remarkably superior to a single weedicide in effect.

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 rimsulfuron-methyl, dithiopyr and barnclofen. 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". The area and...
