Abstract

The invention discloses a weeding agent, which comprises, by mass, 10-15 parts of metolachlor, 8-12 parts of polyurethane, 8-12 parts of maifanstone, 3-5 parts of plant ash, 2-6 parts of a wetting agent, 3-5 parts of an anti-freezing agent, 3-8 parts of a thickener, 4-8 parts of an antifoaming agent, 7-10 parts of oxyfluorfen, 2-8 parts of pendimethalin, 7-10 parts of potassium dichlorophenol, 6-15 parts of a catalyst, 10-25 parts of deionized water, and 6-14 parts of polyvinyl alcohol. According to the present invention, the preparation steps are reasonable, and the operations are convenient;and the prepared weeding agent can seriously inhibit the growth of various weeds, even can completely kill weeds by adjusting the ratio, has good inhibition effects on various weeds, and has wide application range.

Description

technical field [0001] The present invention relates to a herbicide. Background technique [0002] With the development of science and technology, the popularization and application of chemical herbicides has been taken as one of the powerful measures to increase production in labor-saving, time-saving and cost-saving ways. There are many kinds of herbicides at present, among which glyphosate, rimsulfuron, paraquat, Wenshade, Gaiconeng, and thatraquat are the representative ones. These herbicides have played a certain role in the control of weeds. However, the vast majority of weeds are multi-family, multi-weed symbiosis, seeds, young shoots, young grass, and adult grass are intertwined, and these herbicides are used in a single dose, or can only kill weeds on the ground green part. Contents of the invention [0003] The purpose of the present invention is to provide a herbicide to solve the problem of single herbicide weeding. [0004] In order to achieve the above obj...
