A kind of sorghum field chemical herbicide seed coating agent and herbicide method

Abstract

The invention relates to a seed coating agent for chemical weeding in sorghum fields and a herbicidal method. The sorghum seeds are coated according to a certain dose of fluorinated fluorine and other synergistic components, which are absorbed into the body during the germination process of the seeds, and can accelerate the metabolism of the seeds in the body Metolachlor, removes the harm of metolachlor to sorghum seedlings, and makes the seedlings grow normally; while the annual grass weeds and some broad-leaved weeds in the soil, such as goosegrass, crabgrass, daughter, Setaria, amaranth, purslane, etc., absorb metolachlor when they germinate, inhibit the synthesis of weed protein and die. The weeding method is economical, efficient, safe for sorghum growth, and has the effect of strengthening seedlings.

Description

[0001] A kind of sorghum field chemical herbicide seed coating agent and herbicide method technical field [0002] The invention relates to a seed coating agent for chemical weeding in a sorghum field and a weeding method, belonging to the technical field of sorghum seed treatment and field weeding. Background technique [0003] sorghum 【Sorghum bicolor (L.) Moench】 It is the fifth largest food crop in the world and is widely planted in Africa, Asia, Latin America and other places. Sorghum has been cultivated in China for more than 5,000 years. In the 1950s and 1960s, sorghum was widely planted in my country and was the main grain in the north. Sorghum is the main raw material for brewing wine and vinegar. At present, the planting area of ​​sorghum in my country is about 10 million mu, and sorghum is mainly used for brewing. Modern scientific research shows that tannins and resistant starch in sorghum are beneficial to human health, and have therapeutic effects on obesity,...

AI Technical Summary

Problems solved by technology

In arid and semi-arid areas, when metolachlor was sprayed in sorghum fields, sorghum seedlings did not encounter rainfall before the 5th leaf, and the seedlings could grow normally; but in the humid south, after spraying metolachlor, sorghum seedlings with 5th leaf In case of rainfall before, the leaves of the seedlings will be distorted and metamorphosed, causing severe phytotoxicity, failing to grow and causing the seedlings to die, resulting in severe production reduction

[0005] At present, many sorghum experts are conducting research on the problem of sorghum weeding, trying to screen out new sorghum herbicides. Although some new agents have been tried in sorghum production, the weeding effect is not good
