Problems solved by technology

[0013] At present, lawn herbicides are limited by the safety of lawns, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of lawn weeds. Long, excessive dosage or uneven application are likely to cause residual toxicity to the lawn

Abstract

The invention discloses a mixed herbicide containing flazasulfuron and trifluralin. The herbicide uses flazasulfuron and trifluralin as main effective components, wherein the mass ratio of flazasulfuron to trifluralin is 1-80: 1-80. The mixed herbicide of the invention has significant effects on lawn weeding, specifically on control of various Gramineae, Cyperaceae and broadleaf weeds of lawn. Compared with a single agent, on the premise of improvement of herbicide effects, the herbicide of the invention has the advantages of delaying of weed resistance, wide weeding spectrum, long duration and safety to the 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 trifluralin. 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 ...
