Embodiment 1

[0018] Example 1: 50% Azoxystrobin Kasugamycin WP (1:1)

[0019] Azoxystrobin 25%, kasugamycin 25%, sodium lignosulfonate 4%, saponin powder 6%, white carbon black 4%, diatomaceous earth balance.

[0020] The preparation method of the wettable powder is as follows: mixing active components and auxiliary materials according to the formula, and performing air-jet milling to obtain the wettable powder.

Embodiment 2

[0021] Example 2: 80% Azoxystrobin Kasugamycin Water Dispersible Granules (1:3)

[0022] Azoxystrobin 20%, kasugamycin 60%, calcium dodecylbenzene sulfonate 5%, starch 5%, alkylphenol polyoxyethylene ether 4%, and the balance of kaolin.

[0023] The preparation method of the water-dispersible granules is as follows: mix the active ingredients and other additives, pulverize them with an ultrafine jet mill, knead and add them to a fluidized bed granulation dryer for granulation, drying, and screening. After that, the water-dispersible granules of the present invention can be obtained.

Embodiment 3

[0024] Example 3: 10% Azoxystrobin Kasugamycin WP (1:1)

[0025] Azoxystrobin 5%, kasugamycin 5%, sodium lignosulfonate 4%, saponin powder 6%, white carbon black 4%, kaolin the rest.

[0026] The preparation method of the wettable powder is as follows: mixing active components and auxiliary materials according to the formula, and performing air-jet milling to obtain the wettable powder.

Abstract

The invention belongs to the field of agriculture, and particularly relates to a bactericidal composition for preventing and controlling botrytis cinerea. The bactericidal composition for preventing and controlling the botrytis cinerea is prepared from azoxystrobin and kasugamycin, wherein the mass ratio of the azoxystrobin to the kasugamycin is (1 to 30) to (30 to 1). Compared with a single agent, the bactericidal composition disclosed by the invention has the advantages that obvious synergism for drug-resistant diseases is realized and the prevention and control effects are improved. The field dosage can be significantly reduced, environmental pollution and pesticide residues can be effectively reduced, and the production and use cost is reduced. Action mechanisms of active components in the bactericidal composition are different from one another, which is beneficial for overcoming disease resistance and delaying the disease resistance.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a fungicidal composition for preventing and treating tomato gray mold. Background technique [0002] Azoxystrobin is a new methoxyacrylate pesticide with a broad bactericidal spectrum. It is effective against cucumber downy mildew, anthracnose, tomato gray mold, blight, wheat powdery mildew, rust, rice blast, and apple scab. Good control effect, low dosage, unique mechanism of action, and certain protective effect, but the cost of single use is relatively high. [0003] Kasugamycin is a low-toxicity, systemic fungicide. It is a special antibiotic for the prevention and treatment of rice blast. In addition, it has a good control effect on various pathogenic fungi such as cucumber downy mildew, anthracnose, bacterial angular spot, tomato gray mold and so on. [0004] There is no relevant report on compounding azoxystrobin and kasugamycin in the prior art. Contents of the ...
