Corn field herbicide

Abstract

The invention discloses a corn field herbicide. The herbicide is prepared from, by weight, 5-7 parts of propisochlor, 4-6 parts of slaked lime, 3-5 parts of trazodone, 20-30 parts of water, 4-6 parts of clethodim, 3-5 parts of triazine, 2-4 parts of ethylamine and 1-3 parts of octacide 264. The weeding effect is good, weeds in the whole growth period of crops can be prevented and killed through one time of herbicide application, and the agent cost is low.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a cornfield herbicide. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, and are a class of substances used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants, and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage.

Problems solved by technology

The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage. One-time treatment agents with little environmental pollution have gradually become the mainstream. Corn is a very important food crop in China. Corn is grown from sowing After the harvest, weeds are often harmed by various weeds. At present, chemical methods are commonly used for weed control. The chemical agents used are mainly acetochlor and broad leaf powder. Due to the short efficacy period of acetochlor, it needs to be used during the growing season of corn. Repeated use of medication is not only labor-intensive, but also costly; although Kuoye powder has a good weeding effect and a long drug effect period, the price is relatively high, which will also lead to increased costs. In order to solve the above disadvantages, the present invention has selected several A new type of pharmaceutical composition with control and weeding effects, and a cornfield herbicide has been developed. The active ingredients in the herbicide of the present invention have a good synergistic effect within a certain range, the control effect is higher than that of a single agent, and the drug properties are maintained. It takes a long time; it is safe for the current corn crop and the subsequent crop crops, and the herbicide safener furoxazole is used to ensure the safety of the corn crop
