Embodiment 1

[0043] According to the conventional preparation production method, the mass percentage of the finally obtained mixed herbicide is measured, taking rimsulfuron-methyl: 1%, dithiopyr: 1%, barnyard: 18%, adding agricultural adjuvant: alkylphenol Polyoxyethylene ether 4%, polyoxyethylene polyoxypropylene block compound 5%, xanthan gum 2%, deployment and mixing, and constantly add vegetable oil in the stirring process, make the whole mixture mass ratio reach 100%, and according to The general procedure is to form a suspended mixed herbicide with a mixed mass ratio of sulfasulfuron-methyl, dithiopyr, and barnclofen in a mass ratio of 20%.

Embodiment 2

[0045] According to the conventional preparation method, the mass percentage of the finally obtained mixed herbicide is measured, taking rimsulfuron-methyl: 3%, dithiopyr: 2%, barnyard: 25%, adding agricultural adjuvant: methylenebis 9% sodium tea 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 form pyridine according to the general steps Sulfururon, dithiopyr, and barnyard cambone are suspended mixed herbicides with a mass ratio of 30%.

Embodiment 3

[0047] According to the conventional preparation method, measured by the mass percentage of the finally obtained mixed herbicide, take rimsulfuron-methyl: 5%, dithiopyr: 4%, barnyard: 1%, and add agricultural adjuvant: lignosulfuron 7% sodium dodecylbenzene sulfonate, 5% sodium dodecylbenzenesulfonate, 5% ammonium sulfate, mix well, and add diatomaceous earth continuously during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and prepare according to the general steps A water-dispersible granular mixed herbicide with a mixed mass percentage of rimsulfuron-methyl, dithiopyr and barnyard cambone at 10%.

Abstract

The invention belongs to the technical field of chemical synthesis, and provides a mixed herbicide comprising three active ingredients of flazasulfuron, dithiopyr and pyributicarb, as well as a preparation method and application of the mixed herbicide. The mass ratio of the flazasulfuron, the dithiopyr and the pyributicarb is (1-70):(1-60):(1-60); the percentage of the total mass of the three active ingredients in the mass of the herbicide is 10-80%. The mixed herbicide provided by the invention has the advantages that the mixed herbicide is high in herbicidal activity, broad in herbicidal spectrum, and long in lasting period, delays weed resistance, and is high in safety, and can be widely used for weeding of lawn and meadow, particularly for various graminaceae, cyperaceae and broad-leafed weed in lawn controlling weed.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide comprising three active ingredients of rimsulfuron-methyl, dithiopyr and barnyard camb, 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...
