Problems solved by technology

Glyphosate is a very common systemic herbicide. Although it can "cut weeds and root out" weeds, it has a short duration and cannot seal the weed seeds. Will grow quickly, also very labor-intensive
And due to the long-term and large-scale use of glyphosate, many weeds have developed resistance to it, resulting in a decline in the weeding effect
And sulfuron-methyl, as a non-cultivated land herbicide, has been widely used in non-cultivated land in recent years. Although its effect is outstanding, this single component not only takes effect very slowly, but also has many weeds due to long-term use. With the emergence of drug resistance, the weeding effect is not as good as before, especially for some fern and shrub weeds.
Therefore, the general response method is to continuously increase the dosage and frequency of use, thereby increasing investment, and even has a high risk of phytotoxicity to crops, and does not really solve the problem

Embodiment 1-7

[0037] The resistant weeds Phragmites reed, goosegrass, ragweed and purslane that are common in non-cultivated land, as well as fern weeds and oleander, which are difficult to control with existing herbicides, were selected as test objects. Acid, glyphosate, dimethyltetrachlor, and sulfuron-methyl are configured by different weight ratios, and the herbicide composition is configured according to Table 1, and the control effect of each concentration combination of the research embodiment and the single agent of the comparative example on these several weeds . The method for configuring the herbicide composition: 1. Weigh the herbicide raw material according to the amount of each component in Table 1; 2. Melt the above-mentioned raw material herbicide, pulverize it into a fine powder, and sieve it for later use; 3. Add the auxiliary herbicide to the fine powder in step 2. agent and water, supplemented with water to 1000 parts of total weight, fully stirred, making it a uniform m...

Embodiment 8

[0049] Embodiment 8 (indoor biological activity test)

[0050] In order to further verify the herbicidal effect of the above-mentioned preferred herbicide composition and its different mixed combinations, and evaluate whether it has produced a synergistic effect or a synergistic additive effect in the control of non-arable land weeds, imazethapyr, glyphosate Phosphine, dimethyltetrachloride, and sulfuron-methyl, four single agents, two of them combined with each other, three of them combined with each other, and four single-agent compound combinations were used as the research objects. Goosegrass and broad-leaved ragweed were the test targets, and an indoor bioactivity test was set up. The specific test implementation method is as follows:

[0051] Treatment agent: with an electronic balance (sensitivity 0.1mg), weigh 0.0751g of 98% imazapyr original drug, and add 5ml of methanol to fully dissolve it, dilute to 500ml with 0.1% Tween-80 aqueous solution, and prepare Imazapyr ...

Abstract

The invention provides a herbicide composition and its application. The herbicide composition comprises raw materials according to the following weight ratio: 12-125 parts of imazethapyr, 15-270 parts of glyphosate, 3 parts of phenoxycarboxylic acids ~55 parts, 5~90 parts of sulfonylurea components. The herbicide composition provided by the invention belongs to the broad-spectrum systemic conduction type herbicide, and has the advantages of quick effect, wide herbicidal spectrum, capable of sealing and killing, and long-lasting effect. It can be used as an ideal herbicide for non-cultivated land, overcome the shortcoming of weed resistance caused by long-term use of a single agent, make up for the shortcomings of existing herbicides for non-cultivated land in the actual application process, and increase the variety of herbicides for non-cultivated land usage options.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation, and in particular relates to a herbicide composition and its application. Background technique [0002] Weeds grow in non-cultivated lands such as railways, highways, airports, telecommunications, warehousing, industrial and mining enterprises, forestry, etc., which affect the appearance, and can easily block signals, cause fires, or become intermediate hosts or wintering places for certain pests and diseases. Occasion operation, production, etc. bring certain hazards. [0003] Weeds in non-cultivated land have always been a relatively difficult problem in the fields of industrial production and transportation. The more common methods mainly rely on manual use of lawn mowers to mow grass or cut by hand. Where conditions allow the use of chemical weeding, most of them use single ingredients such as glyphosate or sulfuron-methyl for weeding. [0004] At present, the methods of weed...
