Cornfield weed killer and preparation method thereof

Abstract

The invention discloses a cornfield weed killer and a preparation method thereof. The cornfield weed killer is prepared from, by weight, 8-10 parts of sodium benzoate, 3-5 parts of acetochlor, 6-8 parts of propisochlor, 6-8 parts of halosulfuron-methyl, 3-5 parts of slaked lime, 7-9 parts of metosulam, 15-25 parts of water and 6-8 parts of fatty alcohol-polyoxyethylene ether. The preparation method is simple and environmentally friendly, and the cornfield weed killer is good in weeding effect, capable of preventing and killing weeds in the whole growth cycle of crops after being applied once and 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 novel pharmaceutical ingredients with control and herbicide effects, and develops a cornfield herbicide and its preparation method. The active ingre...

[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 amines 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 novel pharmaceutical ingredients with control and herbicide effects, and develops a cornfield herbicide and its preparation method. The active ingredients in the herbicide of the present invention are matched within a certain range It has a very good synergistic effect, the control effect is higher than that of a single agent, and the drug property lasts for a long time; it is safe for the current crop corn and the subsequent crop crops, and the herbicide safener furoxazole is used to ensure the safety of corn crops
