Problems solved by technology

[0002] Wheat is a very important food crop in my country. Wheat is often harmed by various weeds from sowing to harvest. Chemical agents are the most effective means of weed control in wheat fields. At present, the main herbicide for weed control in wheat fields is 2.4 Dibutyl ester, florasulam, etc., due to long-term use, the resistance increases, resulting in large dosage, environmental pollution, and increased farmers' application costs. In order to solve the above disadvantages, the present invention selects several kinds of Novel pharmaceutical composition with herbicidal effect, developed a wheat field herbicide and its preparation method

Abstract

The invention discloses a herbicide of wheat fields and a preparation method of the herbicide. The herbicide comprises the following raw materials in parts by weight: 4-6 parts of ethylene oxide, 5-7 parts of chlorimuron-methyl, 2-4 parts of tribenuron-methyl, 4-6 parts of cyhalofop-butyl, 8-10 parts of clopyralid, 5-7 parts of sodium polyacrylate, 3-7 parts of kaolin, 2-4 parts of a surfactant and 10-15 parts of water. The preparation method is simple and environment-friendly, the weeding effect is good, weeds in the whole growing season of crops can be avoided and eliminated when the herbicide is applied at a time, and the herbicide does not influence the next crops.

Description

Technical field [0001] The present invention relates to the technical field of crop herbicides, and specifically to a wheat field herbicide and a preparation method thereof. Background technique [0002] Wheat is a very important food crop in my country. Wheat is often harmed by various weeds from sowing to harvesting. Chemical agents are the most effective means of removing weeds in wheat fields. Currently, the main herbicide used to control weeds in wheat fields is 2.4 Due to long-term use, the resistance of pesticides such as butylbutyl and flusulam increases, resulting in large dosages, environmental pollution, and increased pesticide application costs for farmers. In order to solve the above disadvantages, the present invention selects several pesticides with prevention and treatment capabilities. A new pharmaceutical ingredient with a herbicidal effect has been developed to develop a wheat field herbicide and its preparation method. Contents of the invention [0003] ...
