Embodiment 1

[0022] Formulation Example 1: 15% flucarbazone-sulfuron-methyl wettable powder.

[0023]

[0024] The above formula is coarsely pulverized in proportion, put into a mixer and mixed uniformly, and then jet pulverized to prepare 15% flucarbazone-sulfuron-methyl wettable powder.

[0025] Preparation Example 2: 25% flucarbazone-sulfuron-methyl suspension concentrate.

[0026]

[0027]

[0028] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 25% flucarbazone-chlorpyrazosulfuron suspension concentrate.

Embodiment 3

[0029] Preparation Example 3: 20% flucarbazone-sulfuron-methyl water-dispersible granules.

[0030]

[0031] The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 20% flucarbazone-clopyrazosulfuron water-dispersible granules.

[0032] Formulation Example 5: 10% flucarbazone-sulfuron-methyl oil suspension concentrate.

[0033]

[0034] Dissolve the original drug, solvent and emulsifier in the above formula into a uniform oil phase; mix under high-speed stirring to prepare 10% flucarbazone-sulfuron-sulfuron-methyl oil suspension concentrate.

Embodiment 1

[0035] Biological Assay Example 1: Indoor Toxicity Assay Test.

[0036] experiment material:

[0037] Qianjinzi (seeds collected and preserved in the field).

[0038] Cottonis (seeds collected in the field and preserved).

Abstract

The invention discloses a herbicidal composition, comprising commonly used additives, triafamone and halosulfuron-methyl, wherein the ratio of the triafamone to the halosulfuron-methyl in parts by weight is (10:1) to (1:10); and the total weight percentage of the triafamone and the halosulfuron-methyl in the composition is 1%-80%. The herbicidal composition disclosed by the invention has an obvious synergistic effect on annual weeds in a paddy field; the dosage of pesticides is lowered; the application cost is reduced; the service life of the pesticides is prolonged; and the adverse effects on the ecological environment caused by the pesticides are reduced.

Description

technical field [0001] The herbicidal composition of the present invention uses flucarbazone-sulfentrazone and chlorpyrazosulfuron-methyl as active ingredients and is used for controlling weeds in farmland, especially annual weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Flucarbazone is an amide compound, a broad-spectrum selective post-emergence herbicide, and its mechanism of action is similar to that of sulfonylurea and imidazolone herbicides,...
