Abstract

The invention discloses a mixed herbicide containing rimsulfuron-methyl, pendimethalin and barnyard grass and its application. Composition, the mass ratio of pyrasulfuron-methyl, pendimethalin and barnyard cambium is 0.1-80:0.1-80:0.1-80. The application of the mixed herbicide of the present invention in lawn weeding, especially in the application of controlling grasses, sedges and broad-leaved weeds in lawns has remarkable effects. Compared with a single agent, the herbicide of the present invention delays weed resistance, has a wide weeding spectrum, long duration of action and is safe for lawns on the premise of improving the efficacy 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 flazasulfuron-methyl, pendimethalin and barnyardgrass, and the herbicide composition can be applied to lawn before seedlings , Weeding after seedling. Background technique [0002] With the acceleration of my country's urbanization process, the improvement of urban greening standards and the substantial growth of urban area, various lawns have emerged as the times require, triggering a huge demand for lawns, and the development of lawn industry has good business opportunities. Lawn is an important auxiliary facility in ensuring that infrastructure such as roads, railways, airports, reservoirs, river banks, and lake embankments are strong and beautiful; in 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 ...
