Embodiment 1

[0061] A bactericidal composition containing prochloraz manganese complex, each raw material component and consumption are as follows:

[0062] Raw material dosage (parts by weight)

[0063] Prochloraz manganese complex technical 20%;

[0064] Copper 10%;

[0065] Wetting agent 4%;

[0066] Dispersant 6%;

[0067] Silica 4%;

[0068] Kaolin 56%.

[0069] This example is used to control cucumber brown spot disease. The wettable powder of this embodiment is diluted and sprayed with 4000 times of water, and the control effect after 3 days of application is 92.7%. 25% prochloraz manganese complex suspending agent is used at 1000 times and 50% thiabendin copper wettable powder is used at 2500 times by the same method, and the control effects after 3 days of drug are 81.3% and 78.7% respectively. The synergistic effect of prochloraz-manganese complex and thiabyl copper compound is obvious, and the control effect on cucumber brown spot is obviously better than that of single a...

Embodiment 2

[0071] A bactericidal composition containing prochloraz manganese complex, each raw material component and consumption are as follows:

[0072] Raw material dosage (parts by weight)

[0073] Prochloraz manganese complex original drug 400%;

[0074] Syringstrobin technical 3%;

[0075] Wetting agent 4%;

[0076] Dispersant 4%;

[0077] Silica 5%;

[0078] Emulsifier 10%.

[0079] Water 34%

[0080] This example is used to control citrus anthracnose. The suspending agent of this embodiment is diluted with water by 2500 times and sprayed, and the control effect after 3 days of application is 91.9%. 25% prochloraz manganese complex suspending agent was used at 1000 times and 255g / L syringstrobin suspending agent at 1000 times, and used in the same way, the control effects were 83.3% and 82.7% respectively 3 days after the drug. The synergistic effect of prochloraz manganese complex and syringstrobin compound is obvious, and the control effect on citrus anthracnose is obvio...

Embodiment 3

[0082] A bactericidal composition containing prochloraz manganese complex, each raw material component and consumption are as follows:

[0083] Raw material dosage (parts by weight)

[0084] Prochloraz manganese complex technical 30%;

[0085] Difenoconazole technical 10%;

[0086] Emulsifier 12%;

[0087] Methanol 10%;

[0088] Xylene 5%;

[0089] Water 33%.

[0090] This example is used to control cucumber leaf spot. The aqueous emulsion of the present embodiment is diluted and sprayed with 2500 times of water, and the control effect after 3 days of application is 93.2%. 40% prochloraz manganese complex suspending agent was used at 1000 times and 255g / L paclobutrazol suspending agent at 1000 times, and used in the same way, the control effects were 82.5% and 83.8% respectively 3 days after the drug. Prochloraz manganese complex and difenoconazole have obvious synergistic effects after compounding, and the control effect on cucumber leaf blight is obviously better than...

Abstract

The invention relates to a fungicidal composition containing a prochloraz manganese complex, belonging to the technical field of pesticides. The fungicidal composition comprises a raw pesticide compounded by a fungicide A and a fungicide B, wherein the mixture ratio of the fungicide A to the fungicide B is (1-90): (90:1); the fungicide A is the prochloraz manganese complex; and the fungicide B is any one type of the following fungicides: copper preparations, strobilurins, triazoles, amides, pyrimidinamines, benzimidazoles, thiocarbamates, dimethyl imides, imidazoles, morpholines, oxazoles, ureas, pyridines, pyrimidines, pyrroles, phthalimides, carbamates, antibiotics, heterocycles and others. The fungicidal composition disclosed by the invention contains the raw pesticide compounded by the prochloraz manganese complex and the fungicide B, and can expand the fungicidal spectrum, slow down the drug resistance of pathogenic bacteria and realize an obvious sustained synergistic effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition containing prochloraz manganese complex. Background technique [0002] Fungicides are a class of pesticides used to prevent and control plant diseases caused by various pathogenic microorganisms, generally referring to fungicides. However, internationally, it is usually used as a general term for agents to prevent and control various pathogenic microorganisms. With the development of fungicides, subclasses such as bactericides, virucides, and algicides are distinguished. According to the survey, there are more than 80,000 kinds of pathogenic microorganisms (fungi, strong bacteria, rickettsia, mycoplasma, viruses, algae, etc.) harmful to plants in the world. The use of fungicides is a cost-effective method of controlling plant diseases. [0003] Early fungicides were all inorganic compounds, among which sulfur powder and copper preparations (such a...
