Embodiment 1

[0024] Example 1: Preparation of wettable powder.

[0025] 20% effective component (A) and 20% effective component (B), 3% sodium lauryl sulfate as wetting agent, 5% carboxylate as dispersant, and 5% as dispersant Sulfonate, 15% white carbon black and other inert fillers are thoroughly mixed and superfinely pulverized to obtain a wettable powder.

Embodiment 2

[0026] Example 2: Preparation of water dispersible granules.

[0027] 35% effective component (A) and 35% effective component (B), 5% carboxylate as wetting agent, 5% NNO as dispersant, 4% lignin sulfonic acid as dispersant Calcium and other inert fillers are thoroughly mixed together and superfinely pulverized, and then an appropriate amount of water and binder mixture is added and dried through fluidized bed granulation or extrusion granulation to obtain water dispersible granules.

[0028] Biological embodiment:

[0029] Example 1: The control effect of the mixed use of sulfomesulfuron and fenoxaprop-p-ethyl on weeds in wheat fields is shown in the table

[0030] Location: Xinyi, Jiangsu Period of investigation: 20 days after drug administration Time: 2010

[0031]

[0032] Conclusion: The actual control effect of the mixed use of sulfomesulfuron and fenoxaprop-p-ethyl is greater than the theoretical control effect, indicating that the mixed use of fensulfuron-methyl and fenoxaprop-...

Abstract

The invention discloses an imazosulfuron-containing weeding composition, and a preparation method and use thereof. The imazosulfuron-containing weeding composition consists of a compound (A) imazosulfuron and a compound (B) fenoxaprop-p-ethyl, wherein the weight ratio of the compound (A) to the compound (B) is 1-50:1-50. The weeding composition of the invention can be prepared into the conventional pesticide forms of wettable powder, water dispersible granule and the like by modern pesticide preparation processing technology after the mixing according to a proper proportion, is used for preventing and killing the annual gramineous weeds and broadleaf weeds of amur foxtail, cleavers, chickweed, pineappleweed, wild oats and the like with remarkable prevention effect better than that of the independently-applied compound (A) or the independently-applied compound (B), and greatly reduces the application amounts of each active substance.

Description

Technical field [0001] The present invention relates to a herbicidal composition with improved properties, in particular to a herbicidal composition containing sulfimuron-methyl and fenoxaprop-p-ethyl and its use. Background technique [0002] The general name of compound (A) is oxsulfuron-methyl and the chemical name is 5-(4,6-dimethylpyrimidin-2-ylcarbamoylaminosulfonyl)-1-(2-pyridyl)pyrazole- Methyl 4-formate. [0003] The other name for azosulfuron is NC330. The CA registration number is 114874-05-4. [0004] Trisulfuron is a sulfonylurea herbicide that inhibits the synthesis of side chain amino acids by inhibiting the activity of acetolactate synthase in plant cells. Trisulfuron-methyl is mainly used to control grassy weeds and vicious broad-leaved weeds in wheat fields, such as Mai Niang, Sorrel, Chrysanthemum, Chamomile, Wild oats, etc., and its control effect on broad-leaved weeds is better. Good, poor control effect on grass weeds. [0005] The Chinese common name of comp...
