Sugarcane field herbicide for low-volume spraying

Abstract

The invention discloses sugarcane field herbicide for low-volume spraying. The herbicide is in a form of a suspending agent; the pesticide ingredients include ametryn and herbicide II, wherein the herbicide II is prepared from one or combination of two of agroxone, diuron, hexazinone, tebuthiuron, halosulfuron-methyl, trifloxysulfuron, mesotrione or topramezone. According to the sugarcane field herbicide for low-volume spraying, ametryn and the herbicide II are mixed in a certain ratio and have synergistic effect on removing weeds of a sugarcane field, and the prevention and treatment effect is obviously superior to that of single agent; meanwhile, the herbicide can be prepared into the suspending agent for low-volume spraying, and therefore, the drift possibility can be obviously reduced, and the wetting and spreading performances of the components of pesticides can be improved; the herbicide also has the advantages of labor saving, water saving, drug saving, high in efficiency, long acting, environmental protection, and low in cost; the labor intensity can be greatly alleviated; the manual drug applying efficiency is improved, the labor can be greatly released, the agricultural production cost can be reduced, and the modern level of weeding the sugarcane field can be increased.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a suspension agent for controlling weeds in sugarcane fields by low-capacity spraying. Background technique [0002] Due to successive years of drought in sugarcane dominant production areas in recent years, sugarcane diseases, insect pests and weeds continue to occur, seriously restricting the normal development of the sugarcane industry; tracking and analyzing the agronomic process of sugarcane production, the inventor has made it clear that weeds in the sugarcane field are the main factors that affect the normal production of sugarcane. most important factor. Weeds in sugarcane fields have the greatest impact on sugarcane from seedling emergence to tillering stage, and are harmed by weeds almost throughout the growing season. If effective control is not carried out, sugarcane production will generally be reduced by 20-30%, and in severe cases, the production will be reduce...

AI Technical Summary

Problems solved by technology

However, sugarcane weeding is extremely labor-intensive and labor costs are high, resulting in rising sugarcane production costs year after year, seriously affecting the enthusiasm of sugarcane farmers for production;

[0005] 3. The types and formulations of chemical herbicides currently used in China are seriously outdated, the application equipment and methods are outdated, and the methods and techniques used have not been improved for decades. As a result, the ideal method of chemical weeding in sugarcane fields has not been able to fully reflect its advantages.

[0006] 4. Due to the increase in weed resistance year by year, the amount of traditional herbicides has increased rapidly. Compared with the amount per mu in 2000, the amount has increased by more than 50%, and the cost has greatly increased

[0007] 5. The currently commonly used sugarcane herbicide is wettable powder, which produces a lot of dust during production and use, which is not conducive to health and environmental protection;

[0008] 6. The dilution factor of herbicides in common sugarcane fields is 300-500 times. It is easy to stratify when spraying with water, and some solid fillers are deposited, which is easy to block the spraying equipment. Dispersion, serious clogging of spray equipment
