Problems solved by technology

[0013] At present, lawn herbicides are limited by safety and herbicidal spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in paddy fields. Moreover, some herbicides are not effective due to their large water solubility or long-lasting effect in the field. Too long, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention discloses a mixed herbicide containing flazasulfuron to oxadiargyl. The herbicide uses flazasulfuron and oxadiargyl as main effective components, wherein the mass ratio of flazasulfuron and oxadiargyl 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 propargyl oxadiazone. The herbicide composition can be applied to lawn weeds before or after emergence After 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 are...
