Embodiment 1

[0030] Weigh 30% cyclostrobin, 2% Zhongshengmycin, 6% calcium lignosulfonate, 3% SOPA, 5% white carbon black, and diatoms to 100% by weight, and fully mix the above components, After being pulverized by an ultra-fine pulverizer, a wettable powder with 32% cyclostrobin and Zhongshengmycin content can be obtained.

Embodiment 2

[0032] Weigh 30% cyclostrobin, 5% Zhongshengmycin, 4% alkylphenol polyoxyethylene ether, 10% NN0, 15% urea, and corn starch to 100% by weight, and mix the above components fully Pulverized, boiled and dried, then granulated to make water-dispersible granules containing 35% cyclostrobin and Zhongshengmycin.

Embodiment 3

[0034] Weigh 50% cyclostrobin, 10% Zhongshengmycin, 3% sodium dodecylbenzene sulfonate, 8% sodium methylene bis-naphthalene sulfonate, 3% propylene glycol, and add water to 100% by weight, Using water as the medium, mix the above-mentioned components well and add them into a sand mill for grinding and processing to obtain a suspension containing 60% cyclostrobin and Zhongshengmycin.

Abstract

The invention provides a bactericide, and particularly provides an agriculturally bactericidal composition. The composition comprises two components: 2-cyano-3-phenyl-3-aminoethyl acrylate and ethylicin, wherein the mass ratio of the components I to the component II is (1:5)-(30:1), and the total mass of the two components takes up 5%-80% of that of the composition. The composition is low in toxicity, slight in damage to people and livestock and ecological environment, and capable of delaying the generation and development of pathogen drug resistance, and has high prevention and treatment effects on the crop disease caused by fusarium, especially on wheat fungoid disease. The bactericidal composition has wide application prospects.

Description

technical field [0001] The invention relates to the field of bactericides, in particular to a bactericidal composition containing cyclostrobin (component 1) and Zhongshengmycin or acetolicin (component 2). Background technique [0002] Cyclostrobin, the chemical name is: ethyl 2-cyano-3-amino-3-phenylacrylate. Cyclostrobin belongs to the xylem translocation agent, which mostly accumulates in parts with high transpiration intensity (leaf margin, leaf tip), and almost no drug reaches organs or parts with very weak transpiration (fruits, seeds, etc.). At the same time, it is found that the medicament is resistant to rain erosion, has good systemic penetration performance and excellent protective and therapeutic effects. Cyanostystrobin has high biological activity against Fusarium graminearum, Fusarium moniliforme, and Fusarium oxysporum of the Fusarium genus, and is suitable for the treatment of crop diseases such as wheat head blight, rice bakanae disease, and watermelon wil...
