Herbicide containing quinclorac, pyrazosulfuron-ethyl and fenoxaprop-p-ethyl

Abstract

The invention discloses a herbicide containing quinclorac, pyrazosulfuron-ethyl and fenoxaprop-p-ethyl. The herbicide is prepared from the following components in percentage by mass: 30 to 60 percentof quinclorac, 5 to 20 percent of pyrazosulfuron-ethyl, 5 to 15 percent of fenoxaprop-p-ethyl, and agriculturally acceptable auxiliaries including calcium lignosulphonate, carrier kaolin and white carbon black. The preparation method comprises the following steps: weighing quinclorac, pyrazosulfuron-ethyl, fenoxaprop-p-ethyl, calcium lignosulphonate, white carbon black and kaolin according to a given amount, adding into a high-speed stirrer, uniformly mixing and stirring, and crushing by adopting a jet mill to obtain a wettable powder product. The use method comprises the following steps: in the 7-8-leaf stage of weeds after winter, weighing the herbicide according to the ratio of 40-70g / mu, and adding water for use. The herbicide is high in safety, low in environmental pollution, wide inweeding spectrum and lasting in pesticide effect, and can be applied to lawn weeding; the weeding composition can also be used for annual weeds in direct-seeding rice fields or transplanting fields.

Description

technical field [0001] The invention relates to a herbicide containing quinclorac, pyrazosulfuron-methyl and fenoxaprop-ethyl, belonging to the technical field of pesticides. 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.
