Wheat field herbicide

Abstract

The invention discloses a wheat field herbicide, which comprises the following raw materials by weight: 5-7 parts of pyroxsulam, 3-5 parts of talcum powder, 4-6 parts of a surfactant, 3-5 parts of carfentrazone-ethyl, 4-6 parts of chlorimuron-ethyl, 8-12 parts of tribenuron-methly, 4-6 parts of sodium polyacrylate, 3-5 parts of aminopyralid, and 10-20 parts of water. The wheat field herbicide provided by the invention has simple and environment-friendly preparation method, good weeding effect, can control weeds of crops within a whole growth period by one application, and has no influence to next-stubble crops.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a wheat field herbicide. Background technique [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 A novel medicinal composition with herbicidal effect, a wheat field herbicide has been developed, the herbicide of the present invention has a synergistic effect, and the effect of controlling annual weeds in the wheat field is obviously better than that of each single agent used alone, and the herbici...
