Problems solved by technology

Glyphosate and glufosinate are highly water-soluble, and there is a high risk of leaching into groundwater or surface runoff to pollute surface water
2M, 4-Cl and fluroxypyr have a medium persistence period. Although they are still active when sprayed on the soil surface, the persistence period is not long, and the risk of leaching into groundwater or surface water pollution by surface runoff is average
[0006] Although the herbicides registered and used on non-cultivated land are either biocidal, or sulfonylureas and sulfonamides with a broad herbicidal spectrum and high activity, the problem of weed resistance is becoming more and more serious with successive years of use

Embodiment 1

[0028] Example 1 Preparation of haclopyridine (1g) and diquat (75g) aqueous suspension

[0029] Use 96% halauxifen-methyl original drug and 91% diquat original drug to prepare water suspension. Use an electronic balance to weigh the quantitative amounts of fluclopyridine and diquat respectively, first add a special emulsifier to dissolve, then add 2 times of N,N-dimethylformamide until completely dissolved, and use 0.1% diquat Dilute the warm-80 aqueous solution into 1% water suspension concentrate for later use. Prepare the active ingredient haclopyridine (1g) and diquat (75g) compound water suspension concentrate, and the prepared water suspension concentrate can be used for one hectare.

Embodiment 2

[0030] Example 2 Preparation of compound water suspension concentrate of haclopyridine (1g) and diquat (150g)

[0031] The preparation method is the same as that in Example 1, and the preparation is carried out by weighing the haclopyridine axetil and the diquat original drug.

Embodiment 3

[0032] Example 3 Preparation of compound water suspension concentrate of halopyxate (1g) and diquat (300g)

[0033] The preparation method is the same as that in Example 1, and the preparation is carried out by weighing the haclopyridine axetil and the diquat original drug.

Abstract

The invention belongs to the technical field of farm chemical herbicides, and particularly relates to a herbicide composition containing halauxifen-methyl and diquat. The herbicide composition is suitable for uncultivated land. The weight ratio of the active ingredient halauxifen-methyl to the active ingredient diquat ranges from 1:9.4 to 1:600. According to the herbicide composition, the weed control spectrum is broadened, the control effect is enhanced, the situation that the herbicide resistance of weeds can be rapidly generated when weed control is performed with a single herbicide is avoided, generation of the herbicide resistance of weeds is retarded, the dosage is reduced, the use cost is lowered, and environmental pollution is relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicide composition containing haclopyridil and diquat suitable for non-cultivated land. Background technique [0002] Weeds in non-cultivated land mainly include weeds in woodlands, lawns, roads, railways, warehouses, field ridges, ditches, and beside forest fire escapes. The growth of weeds in non-cultivated land affects the appearance of the city, or becomes the intermediate host or overwintering place of certain pests and diseases, thus bringing certain harm to urban greening or agricultural production. Chemical herbicides on non-cultivated land in my country are weed control without involving the cultivation of stubble crops. Generally, the registered herbicides are mainly destructive and long-lasting. Chemical weeding in non-cultivated land has also developed rapidly in recent years, but there are great differences in the types of weeds, herbic...
