Embodiment 1

[0034] Example 1: Preparation of wettable powder.

[0035] With 10% active ingredient (A) and 30% active ingredient (B1) or active ingredient (B2), 2% sodium lauryl sulfate as wetting agent, 15% carboxylate as dispersant, 5% sulfonate as a dispersant, 20% white carbon black and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Embodiment 2

[0036] Example 2: Preparation of dispersible oil suspension concentrate.

[0037] 10% active ingredient (A) with 20 active ingredient (B1) or active ingredient (B2), 15 carboxylate as emulsifier, 2% organic bentonite as thickener, supplemented with corn oil After 100%, it is put into a sand mill for grinding to obtain a dispersible oil suspension.

Embodiment 3

[0038] Example 3: Preparation of water-dispersible granules.

[0039] With 20% active ingredient (A) and 50% active ingredient (B1) or active ingredient (B2), 6% carboxylate as wetting agent, 6% NNO as dispersant, 4% as Calcium lignosulfonate as a dispersant and other inert fillers are thoroughly mixed together and ultrafinely pulverized, then an appropriate amount of water and binder is added to the mixture, and the water can be obtained by fluidized bed granulation or extrusion granulation and drying. Dispersible granules.

[0040] Biological example:

[0041] Example 1: The control effect of rimsulfuron-methyl and sulcotrione on weeds in cornfield is shown in the table

[0042] Location: Xinyi, Jiangsu Province Investigation period: 20 days after taking the medicine Time: 2010

[0043]

[0044] Conclusion: The actual control effect of the mixed use of rimsulfuron-methyl and sulcotrione is greater than the theoretical control effect, indicating that the mixed use of ri...

Abstract

The invention relates to an amidosulfuron-containing weeding composition as well as a preparation method and application thereof. The amidosulfuron-containing weeding composition comprises a compound (A) of amidosulfuron and a compound (B) selected from sulcotrione and nitro sulcotrione, wherein the weight ratio of the compound (A) to a compound (B1) or a compound (B2) is 1:1-50. After being mixed according to a proper proportion, the weeding composition can be processed into a normal pesticide formulation, such as wettable powder, dispersible oil suspending agent, water dispersible granule, and the like through the processing technology of a modern pesticide preparation, and is used for controlling and eliminating annual broadleaf weeds and some gramineae weeds, such as abutilon, burweed, amaranthus spinosus, chenopodium weeds, kochia scoparia, polygonum weeds, mustard leaves, cockspur grass, crabgrass, and the like in corn fields. The controlling effect of the weeding composition is remarkably higher than that of the single compound (A) or the single compound (B), and the application dosage of each active substance is greatly reduced.

Description

technical field [0001] The present invention relates to herbicidal compositions with improved properties, in particular to herbicidal compositions containing rimsulfuron-methyl and a selected from sulcotrione or mesotrione and their use. Background technique [0002] The general name of the compound (A) is sulfuron-methyl, and the chemical name is 1-(4,6-dimethoxy-2-pyrimidinyl)-3-(N-methylmethanesulfonamidesulfonyl)-urea. [0003] The English name of amidosulfuron: amidosulfuron. Other names are: Allstate, Hoestar, hoe0750032. The CA registration number is: 120923-37-7. [0004] Sulfuron-methyl is a high-efficiency sulfonylurea and high-efficiency herbicide, belonging to the sulfonylurea herbicides, which can control broad-leaved weeds in wheat and corn fields. Weeds inhibit cell division through stem and leaf absorption, and plants stop growing and die. [0005] Currently, the formulations of rimsulfuron-methyl used in the market mainly include 50% rimsulfuron-methyl w...
