Embodiment 1

[0065] Example 1: 30.3% Thiophanate Methyl Suspending Concentrate (1:100)

[0066] Components: Thiophanate Methyl 0.3%, Thiophanate Methyl 30%, Acrylic Acid-Hydroxypropyl Acrylate Copolymer 5%, Fatty Alcohol Polyoxyethylene Ether 3%, Ethylene Glycol 6%, XG0.3%, Organic Silicon defoamer 0.2%, sodium benzoate 0.6%, soft water make up to 100%.

[0067] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and you can prepare 30.3% thiamin. Thiophanate-based suspension.

Embodiment 2

[0074] Embodiment 2: 32.4% thiophanate-methyl water dispersible granules (1:80)

[0075] Components: Thiophanate 0.4%, Thiophanate Methyl 32%, Sodium Polycarboxylate 3%, Sodium Lignosulfonate 6%, Sodium Sulfate Anhydrous 8%, Kaolin Clay Supplemented to 100%.

[0076] Preparation method: Mix the components, crush them mechanically, then crush them by air flow, mix them evenly, then wet granulate them and dry them to get 32.4% thiophanate-methyl water dispersible granules agent.

Embodiment 3

[0082] Embodiment 3: 30.6% thiophanate-methyl dry suspension (1:50)

[0083] Components: Thiophanate Methyl 0.6%, Thiophanate Methyl 30%, Sodium Polycarboxylate 4%, Sodium Lignosulfonate 8%, White Carbon Black 8%, Silicone Defoamer 0.4%, Sodium Benzoate 0.1 %, kaolin makes up to 100%.

[0084] Preparation method: add 1.5-2.0 times the amount of water prepared by the preparation, mix the components, mix them evenly through high-speed shearing, and then sand them with a sand mill for 2-3 hours to make the average particle size reach 1-5 microns, dehydrate After drying, 30.6% thiamid-methylthiophanate-methyl dry suspension can be prepared.

Abstract

The invention provides a bactericidal composition and an application thereof, wherein the effective ingredients of the bactericidal composition are methiadinil and thiophanate-methyl, and the weight ratio of the methiadinil and thiophanate-methyl is 1:100-100:1. The compound of methiadinil and thiophanate-methyl has obvious synergism and can effectively reduce the dosage of each single dose. The composition can be processed into any dosage form by adding auxiliary ingredients that are permissible in the remaining pesticides. The bactericidal composition is mainly used for controlling Fusariumhead blight, apple ring rot, smut, sheath blight, sclerotinia sclerotiorum, black spot, downy mildew, early blight, Phyricularia oryzae, wheat powdery mildew, banana leaf spot and virus disease.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericide composition containing thiophanate-methyl and thiophanate-methyl and its application. Background technique [0002] Pesticides have played a huge role in increasing agricultural production and ensuring income with the characteristics of fast, effective and low price. However, unscientific and single use of pesticides have led to the continuous enhancement of bacterial resistance and the continuous increase of pathogenic varieties. At the same time, frequent use of pesticides is also It increases the economic burden, and leads to a series of serious ecological and social problems of environmental pollution and agricultural product safety. With the continuous improvement of people's living standards, the concern for environmental protection and the safety and quality of agricultural products have put forward higher requirements. Therefore, how to use scientifica...
