Corn field herbicide

Abstract

The invention discloses a corn field herbicide. The corn field herbicide comprises, by weight, 5-15 parts of fluthiacet-methyl, 6-8 parts of isoxaflutole, 20-30 parts of water, 7-9 parts of a wetting agent, 4-6 parts of atrazine, 5-7 parts of propisochlor, 5-7 parts of sodium dodecyl sulfate and 6-8 parts of foramsulfuron. The herbicide has the advantages of simple and environmentally friendly preparation method, good weeding effect, realization of control of weeds of crops in the whole growth period through one-time herbicide application, and low medicine cost.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a cornfield herbicide. 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 is increased. In order to solve the above disadvantages, the present invention selects several new pharmaceutical ingredients with control and weeding effects, and develops a cornfield herbicide, which has a partial synergistic effect on broad-leaved weeds. , has an additive eff...

[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 is increased. In order to solve the above disadvantages, the present invention selects several new pharmaceutical ingredients with control and weeding effects, and develops a cornfield herbicide, which has a partial synergistic effect on broad-leaved weeds. , has an additive effect on grass weeds, has no effect on the safety and growth of corn, can improve the control effect, expand the herbicidal spectrum, reduce the amount of active ingredients, save the cost of medication, and reduce environmental pollution
