Embodiment 1

[0044] According to the conventional preparation method, measured by the mass percentage of the finally obtained mixed herbicide, take rimsulfuron-methyl: 1%, dithiopyr: 1%, fensulfame: 18%, mix evenly, and add agricultural adjuvant : Alkylphenol polyoxyethylene ether 4%, polyoxyethylene polyoxypropylene block compound 5%, xanthan gum 2%, deployment and mixing, and continuously add vegetable oil in the stirring process, so that the mass ratio of the whole mixture reaches 100 %, and follow the general steps to form a suspended mixed herbicide with a mixed mass ratio of sulfasulfuron-methyl, dithiopyr, and flumetsulam at a mass ratio of 20%.

Embodiment 2

[0046] According to the conventional preparation method, measured by the mass percentage of the finally obtained mixed herbicide, take rimsulfuron-methyl: 3%, dithiopyr: 2%, fensulfame: 25%, mix evenly, and add agricultural adjuvants : 9% sodium methylenebisturide sulfonate, 5% alkylphenol polyoxyethylene ether, mix well, and add sodium lignosulfonate continuously during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and follow the The general procedure is to form a suspended mixed herbicide with a mixed mass ratio of sulfasulfuron-methyl, dithiopyr, and flumetsulam at a mass ratio of 30%.

Embodiment 3

[0048] According to the conventional preparation method, it is measured by the mass percentage of the finally obtained mixed herbicide, take rimsulfuron-methyl: 5%, dithiopyr: 4%, fensulfame: 1%, mix well, and add the agricultural adjuvant : 7% sodium lignosulfonate, 5% sodium dodecylbenzenesulfonate, 5% ammonium sulfate, mix well, and continuously add diatomaceous earth as a solid carrier during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and according to the general steps to prepare flusulfuron-methyl, dithiopyr, flumetsulam mixed mass ratio of 10% water-dispersible granular mixed herbicide.

Abstract

The invention belongs to the technical field of chemical synthesis and provides a mixed weedicide containing three compounds of flazasulfuron, dithiopyr and flumetsulam, as well as a preparation method and application of the mixed weedicide. In the mixed weedicide, the mass ratio of flazasulfuron to dithiopyr to flumetsulam is (1-70) to (1-60) to (1-60), and the total mass percent of the three effective ingredients in the weedicide is 10%-80%. The mixed weedicide has the advantages of high weeding activity, wide weeding spectrum, long lasting time, capability of delaying the resistance of weeds and high safety, can be widely applied to weeding of lawns and meadows, and is especially used for preventing and removing various grassy, cyperaceae and broadleaf weeds in the lawns.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and relates to a mixed herbicide comprising sulfasulfuron-methyl, dithiopyr and flumetsulam, and a preparation method and application of the mixed herbicide. 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 green space reflect the e...
