Problems solved by technology

[0006] And usually corn field herbicides all have stronger selectivity, and to one family weeds weeding effect is good but to another family weeds weeding effect is very poor, therefore can only repeatedly, multi-species, multi-dose medication, exceed The amount and abuse of pesticides have brought negative impacts such as rice quality decline and environmental pollution, and increased the cost of pesticides.

Embodiment 1

[0016] A cornfield herbicide composition, said composition is made according to the following raw materials in parts by weight: 28 parts of atrazine, 21 parts of refined metolachlor, 15 parts of metolachlor, 23 parts of acetochlor 5 parts, 5 parts of propachlor, 6 parts of nicosulfuron, and 8 parts of ethoxysulfuron. (1Kg per serving)

Embodiment 2

[0018] A cornfield herbicide composition, the composition is made according to the following raw materials in parts by weight: 20 parts of atrazine, 10 parts of refined metolachlor, 15 parts of metolachlor, 22 parts of acetochlor 5 parts, 5 parts of propachlor, 5 parts of nicosulfuron, and 8 parts of ethoxysulfuron. (1Kg per serving)

Embodiment 3

[0020] A cornfield herbicide composition, said composition is made according to the following raw materials in parts by weight: 30 parts of atrazine, 30 parts of refined metolachlor, 20 parts of metolachlor, 25 parts of acetochlor 6 parts, 6 parts of propachlor, 6 parts of nicosulfuron, and 10 parts of ethoxysulfuron. (1Kg per serving)

[0021] When applying, in the early seedling stage after sowing, the plots without weeds in the field can be closed; after the wheat is harvested, the field plots with more annual weeds can be mixed with the "one seal and one kill" treatment method. .

Abstract

The invention relates to a herbicide composition and especially relates to a corn field herbicide composition. The corn field herbicide composition is prepared from following raw materials, by weight, 20-30 parts of atrazine, 10-30 parts of s-metolachlor, 15-20 parts of metolachlor, 22-25 parts of acetochlor, 5-6 parts of propisochlor, 5-6 parts of nicosulfuron and 8-10 parts of ethoxysulfuron. The corn field herbicide composition is quick in pesticide effects, is strong in drug-delivery lasting period, and is time saving and labor saving. The corn field herbicide composition is more significant that single components in activity. Synergistic effects include wider a weed control spectrum, a quicker weeding effect, a more durable preventing and treating effect. The corn field herbicide composition can control harmful crops better just by one or a few times of drug delivery and can broaden a possible drug delivery interval period.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a cornfield herbicide composition. Background technique [0002] Corn (scientific name: Zea mays), also known as maize, corn, corn, and cob; it is called corn in Cantonese and fanmai in Hokkien. It is an annual grass herb, an important food crop and an important source of feed. The food crop with the highest total output in the world is even higher than that of rice. [0003] Corn is the seed of the herbaceous plant maize. The origin is Mexico or Central America. In 1492, Columbus discovered corn in Cuba, and it has been cultivated throughout North and South America since then. After corn was brought back to Spain in 1494, it gradually spread to all over the world. By the end of the Ming Dynasty, corn had been planted in more than ten provinces, such as Jilin, Zhejiang, Fujian, Yunnan, Guangdong, Guangxi, Guizhou, Sichuan, Shaanxi, Gansu, Shandong, Henan, Hebei, Anhui and other place...
