Embodiment 1
[0031] Example 1: 42% Methienamide·Cyanazazole Suspension Concentrate
[0032] Weigh 2% Methiamin, 40% Cyazofamid, 5% Sodium Polycarboxylate, 2% Sodium Dodecylbenzene Sulfonate, 6% Ethylene Glycol, 0.25% XG, 0.6% Silicone Defoamer , 0.4% sodium benzoate, deionized water added to 100% by weight. Preparation method: Cut the original drug and additives through a high-shear disperser for 30 minutes, mix them evenly, and grind them with a sand mill to a fineness of 1-4 microns to prepare 42% thiamid-cyazofamid suspending agent.
[0034] Weigh 15% Methiamid, 15% Cyazofamid, 3% Phosphate Polyoxyethylene Ether, 4% Nonylphenol Polyoxyethylene Ether, 6% Ethylene Glycol, 0.25% XG, 0.6% Silicone Defoaming Agent, 0.4% sodium benzoate, deionized water added to 100% parts by weight. Preparation method: Cut the original drug and additives through a high-shear disperser for 30 minutes, mix them evenly, and grind them with a sand mill to a fineness of 1-4 microns to prepare 30% thiamid-cyazofamid suspending agent.
Embodiment 3
[0035] Example 3: 22% Methienamide Cyazofamid Water-dispersible Granules
[0036] Take by weighing 20% thiaminide, 2% cyanazimazole, 4% sodium lauryl sulfate, 3% sodium lauryl sulfate, 3% lignin, and kaolin is supplemented to 100% by weight, and each group Separately mix, through mechanical crushing, then through jet crushing, mix evenly, then through wet granulation and drying, you can get 22% Methiamin · Cyazofamid water dispersible granules.

Abstract
The invention discloses a sterilizing composition and applications thereof, and belongs to the field of pesticide. Active ingredients of the sterilizing composition are N-(5-methyl-1,3-thiazole-2-yl)-4-methyl-1,2,3-thiadiazole-5-formamide (A) and an imidazole bactericide (B); weight ratio of (A) to (B) ranges from 1:40 to 40:1, preferably 1:20 to 20:1, and more preferably 1:10 to 10:1. The imidazole bactericide (B) can be selected from cyazofamid, fenamidone, and the like. Auxiliary ingredients allowed to be added into other pesticides can be added into the sterilizing composition so as to process the sterilizing composition into suspending agents, water dispersible granules, wettable powder, and dry suspending agents. The sterilizing composition is capable of preventing and treating club root of crucifer effectively; control efficiency is obvious better than that of single A or B; combination of bactericide with different action mechanisms and action modes is capable of reducing application amount of single ingredients effectively, possesses excellent effects on enlarging bacteriocidal spectrum and delaying generation of plant drug resistance, and is capable of prolonging effect lasting period; and popularization value is high.
Description
technical field [0001] The present invention relates to a fungicide composition, especially a fungicide composition in which formosylamine is used as the first active ingredient, and imidazole fungicides such as Cyazofamid and Mediazolidin are used as the second active ingredient, which belongs to compounding Pesticide technology field. Background technique [0002] In agricultural production, the healthy growth of crops is not only affected by insects and weeds, but also the prevention and control of diseases is very important. With the strengthening of environmental protection concepts and the implementation of sustainable development strategies, high efficiency, low toxicity, high activity, and low residue have become an inevitable trend in the development of pesticides. However, even if high-efficiency fungicides are used alone for a long time, it is easy to cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shortened dur...
