Another example is that in some places where powdery mildew is seriously endangered, common fungicides such as chlorothalonil and mesulphate-methyl have no effect when used alone, and triadimefon has also caused serious resistance due to large-scale application. Sexuality, and prone to phytotoxicity

Embodiment 1

[0045] Example 1 84% azoxystrobin · cyproconazole water dispersible granules

[0046] Azoxystrobin 60%, cyproconazole 24%, dispersant ethylene oxide-propylene oxide block copolymer 2%, calcium lignosulfonate 4%, wetting agent a-sulfo fatty acid methyl ester 0.6% , 0.6% of sodium a-olefin sulfonate, 0.6% of sodium fatty amide N-methyl taurate, 1.0% of disintegrant diammonium hydrogen phosphate, 1.0% of ammonium sulfate, and kaolin to make up to 100%. The fine powder of 750 meshes was obtained by micro-airflow pulverization, and the obtained fine powder was kneaded with water, and then the kneaded material was extruded and granulated, and dried at 50°C to obtain 84% azoxystrobin-cyclaconazole water-dispersible granules.

Embodiment 2

[0047] Example 2 84% azoxystrobin · cyproconazole water dispersible granules

[0048] Azoxystrobin 60%, cyproconazole 24%, dispersant sodium methylene bis-tetrasulfonate 2%, wetting agent sodium dodecylbenzene sulfonate 1.5%, disintegrant potassium sulfate 1.9%, attapulgite Make up the soil to 100%, after mixing evenly, carry out ultra-fine airflow pulverization to obtain 750 mesh fine powder, add water to the obtained fine powder for kneading, then extrude the kneaded material and dry it at 50°C to obtain 84% Azoxystrobin·cyclaconazole water dispersible granules.

Embodiment 3

[0049] Example 3 84% azoxystrobin · cyproconazole water dispersible granules

[0050] Azoxystrobin 56%, cyproconazole 28%, dispersant ethylene oxide-propylene oxide block copolymer 2%, calcium lignosulfonate 4%, wetting agent a-sulfo fatty acid methyl ester 0.6% , 0.6% of sodium a-olefin sulfonate, 0.6% of sodium fatty amide N-methyl taurate, 1.0% of disintegrant diammonium hydrogen phosphate, 1.0% of ammonium sulfate, and kaolin to make up to 100%. The fine powder of 750 meshes was obtained by micro-airflow pulverization, and the obtained fine powder was kneaded with water, and then the kneaded material was extruded and granulated, and dried at 50°C to obtain 84% azoxystrobin-cyclaconazole water-dispersible granules.

Abstract

The invention discloses a sterilization composition containing azoxystrobin and cyproconazole. The azoxystrobin and the cyproconazole are used as active ingredients, and the weight ratio of the azoxystrobin to the cyproconazole is 1-80:1-80. The invention further discloses application of the sterilization composition. The sterilization composition and the application have the advantages that an obvious synergetic effect is realized when the azoxystrobin and the cyproconazole are used together, merits of the azoxystrobin and merits of the cyproconazole are effectively played, the obtained sterilization composition is excellent in quality and high in pesticide effect, and can effectively prevent and treat powdery mildew of cucumbers, a preparation method is simple, operation is convenient, energy consumption is low, the application amount of drugs is reduced when the sterilization composition is used with the drugs, drug resistance of germs to a single drug is relieved, and the sterilization composition has high social and economical benefits.

Description

technical field [0001] The invention relates to a pesticide and its application, in particular to a bactericidal composition containing azoxystrobin and cyproconazole and its application, and belongs to the technical field of pesticides. Background technique [0002] Azoxystrobin (Azoxystrobin), the chemical name is (E) 2-[2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl]-3-methoxymethyl acrylate, Molecular formula is C 22 h 17 N 3 o 5 , the molecular weight is 403.4. Azoxystrobin is a methoxyacrylate (Strobilurin) fungicide, highly effective, broad-spectrum, against almost all fungal kingdoms (Ascomycotina, Basidiomycotina, Flagellate and Deuteromycotina) diseases Such as powdery mildew, rust, glume blight, net spot, downy mildew, rice blast, etc. have good activity. It can be used for stem and leaf spray, seed treatment, and soil treatment, mainly used for grain, rice, peanut, grape, potato, fruit tree, vegetable, coffee, lawn, etc. [0003] Cyproconazole, the chemical...
