Problems solved by technology

[0002] Corn is a very important food crop in my country. Corn is often harmed by various weeds from sowing to harvest. At present, chemical methods are commonly used for weed control. The main chemical agents used are acetochlor and broad leaf powder. The efficacy period of amine is short, so it needs to be used multiple times during the growing season of corn, which is not only labor-intensive, but also high in cost; although Kuoye powder has a good weeding effect and a long efficacy period, its price is relatively high, which will also lead to The cost rises, in order to solve the above-mentioned drawbacks, the present invention selects several new drug ingredients with control and weeding effects, and develops a cornfield herbicide and its preparation method

Abstract

The invention discloses a corn field herbicide and a preparation method thereof. The corn field herbicide is prepared from the following raw materials in parts by weight: 8-15 parts of sodium benzoate, 7-10 parts of pentizidone, 5-8 parts of lauryl sodium sulfate, 2-4 parts of talcum powder, 2-4 parts of N-(2-ethylhexyl)-5-norbornene-2,3-dicarboximide, 5-8 parts of alachlor, 15-20 parts of water, and 5-8 parts of fatty alcohol-polyoxyethylene ether. The preparation method is simple and environment-friendly; the corn field herbicide is good in weed control effect, can prevent and control the weeds in the whole crop growth phase after one-time application, and is low in cost.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a cornfield herbicide and a preparation method thereof. Background technique [0002] Corn is a very important food crop in my country. Corn is often harmed by various weeds from sowing to harvest. At present, chemical methods are commonly used for weed control. The main chemical agents used are acetochlor and broad leaf powder. The efficacy period of amine is short, so it needs to be used multiple times during the growing season of corn, which is not only labor-intensive, but also high in cost; although Kuoye powder has a good weeding effect and a long efficacy period, its price is relatively high, which will also lead to The cost rises. In order to solve the above-mentioned disadvantages, the present invention selects several new drug ingredients with control and weeding effects, and develops a cornfield herbicide and its preparation method.
