Embodiment 1

[0026] Example 1: Preparation of wettable powder.

[0027] 15% active ingredient (A) and 35% active ingredient (B), 2% sodium lauryl sulfate as wetting agent, 5% carboxylate as dispersant, 5% sodium lauryl sulfate as dispersant Sulfonate, 15% white carbon black and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Embodiment 2

[0028] Example 2: Preparation of water-dispersible granules.

[0029] 15% active ingredient (A) with 55% active ingredient (B), 4% carboxylate as wetting agent, 6% NNO as dispersant, 4% lignosulfonic acid as dispersant Calcium 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-dispersible granules can be obtained after fluidized bed granulation or extrusion granulation and drying.

[0031] Example 1: The control effect of rimsulfuron-methyl and atrazine on weeds in cornfield is shown in the table

[0032] Location: Xinyi, Jiangsu Province Investigation period: 20 days after taking the medicine Time: 2010

[0033]

[0034] Conclusion: The actual control effect of the mixed use of sulfuron-methyl and atrazine is greater than the theoretical control effect, indicating that the mixed use of sulfuron-methyl and atrazine has a synergi...

Abstract

The invention discloses a weeding composition containing amidosulfuron and atrazine and a preparation method and application thereof. The weeding composition consists of an amidosulfuron compound (A) and an atrazine compound (B). The weight ratio of the compound (A) to the compound (B) is 1:1-100. The weeding composition can be processed into conventional pesticide formulations such as wettable powder, water dispersible granules and the like by modern pesticide preparation processing technology after being mixed according to a proper proportion, and is used for preventing and removing annual gramineous weeds and broadleaf weeds such as hairy finger, cockspur grass, green bristlegrass, nutgrass flatsedge, amur foxtail, polygonum, goosefoots and the like in corn fields. The prevention effect of the weeding composition is remarkably higher than that of the single compound (A) or the single compound (B), and the application dose 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 sulfuron-methyl and atrazine 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 water-dispersible granules. [0006]...
