Embodiment 1

[0019] Embodiment one: Post-emergence compound herbicide for corn:

[0020] After mixing zinc sulfate and 24% nicotinic acid atrazine according to the weight ratio of 1.5:1, the compound herbicide is obtained.

Embodiment 3

[0021] Embodiment three: Application of compound herbicides after corn emergence:

[0022] With the dosage of 0.25 kg of corn post-emergence herbicide per mu, mix 0.1 kg of zinc sulfate with 0.15 kg of 24% nicotinic acid and atrazine and dissolve in 20 kg of water, and spray the solution on the stems and leaves of corn seedlings at the seedling stage .

[0023] The beneficial effects brought by the compound herbicide after corn seedling of the present invention in cornfield weeding are illustrated below by specific test examples:

Abstract

The invention relates to a post-emergence composite herbicide for corn and an application of the post-emergence composite herbicide, which belongs to the technical field of herbicide production. The post-emergence composite herbicide for corn consists of herbicide and zinc fertilizers according to the weight ratio of 1:1.5. The use method of the post-emergence composite herbicide for corn comprises the following steps: dissolving the post-emergence composite herbicide for corn in water which is 200 times of zinc sulfate in weight; and taking an aqueous solution to spray the stem leaves of corn seedlings in the seedling stage of corn. The post-emergence composite herbicide for corn provided by the invention has the advantages of promoting seedling to premature, strengthening the plant, enhancing the disease resistance and phytotoxicity resistance, improving the carbon metabolism, synthesis of amino acids and activity of enzymes, and promoting nitrogen absorption and transfer as the zinc fertilizers are added into conventional herbicide, a proper amount of zinc element in the use process of post-emergence composite herbicide for corn is added, and zinc is added into the post-emergence herbicide sprayed.

Description

technical field [0001] The invention belongs to the technical field of herbicide production, and in particular relates to a corn post-emergence compound herbicide and its application. Background technique [0002] my country is a large agricultural country. Corn is cultivated all over the country. Corn likes high temperature and generally matures in summer and autumn. Therefore, in summer and autumn, it is hot and rainy, and weeds in cornfields are common. The main weeds are crabgrass, barnyardgrass, foxtail, Goosegrass, retroverted amaranth, purslane, iron amaranth, Cyperus cyperus, etc. Corn seedlings are most seriously harmed by weeds. Chemical control saves time and effort. However, there are various post-emergence herbicides on the market, and farmers often don’t know how to choose. unnecessary damage. Therefore, understanding the types and correct use of herbicides is the key to corn weed control. According to research and analysis, it is found that the post-emergenc...
