Pesticide for weeding of corn field and preparation method thereof

Abstract

The invention provides a pesticide for weeding of a corn field. The pesticide is prepared from the following raw materials in parts by weight: 8 to 10 parts of rhizome of sonchus oleraceus, 6 to 8 parts of root of cinnamomum camphora, 4 to 9 parts of root of dalbergia hupeana, 4 to 8 parts of illicium verum, 3 to 5 parts of root of sorghum milo, 3 to 4 parts of root of tripterygium wilfordii, 2 to 4 parts of radix adenophorae, 1 to 5 parts of remote lemongrass herb, 2 to 4 parts of salvia prionitis, 8 to 14 parts of verticillium powder, 3 to 6 parts of allicin, 2 to 3 parts of flupoxam, 0.1 to 0.15 part of nicosulfuron, 1 to 2 parts of pendimethalin, 0.1 to 0.6 part of amicarbazone, and 8 to 10 parts of ethyl alcohol. The pesticide has the advantages that by adding the traditional Chinese medicine components, the influence to the tillage land by chemical components is effectively relieved, and the common weeds and pests in the corn field can be effectively prevented and removed; the cost is lower, the biodegradability is good, the residue and public nuisance are avoided, and the output and quality of corn are favorably improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a cornfield herbicidal pesticide and a preparation method thereof. Background technique [0002] Maize is an annual grass plant, an important food crop and an important source of feed, as well as the food crop with the highest total yield in the world. At present, the commercially available pesticides for corn fields generally have problems such as poor specificity, low efficacy at low concentrations, and high half-life. Frequent use of pesticides causes great harm and pollution to the environment and corn crops, and there will be trace residues. It is easy to endanger health after human consumption. In addition, most of these pesticides are chemical pesticides, which are easy to cause arable land formation and reduce the utilization rate of arable land and corn yield. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present inventio...

AI Technical Summary

Problems solved by technology

At present, the commercially available pesticides for corn fields generally have problems such as low specificity, low efficacy at low concentrations, and high half-life. Frequent use will cause greater harm and pollution to the environment and corn crops, and there will be trace residues. Hazardous to health after human consumption

In addition, these pesticides are mostly chemical pesticides, which can easily cause arable land compaction, reducing the utilization rate of arable land and corn yield.
