Problems solved by technology

[0008] At present, with the change of planting structure, the degree and number of diseases of melons, fruits, vegetables, and cereal crops have increased, and it is more difficult to prevent and control objectively; Under pressure, the resistance of pathogenic bacteria has increased year by year, and the control effect of a single agent has been greatly reduced; third, the current introduction of new pesticide varieties has dropped significantly, and there is a lack of new target agents; fourth, due to increasingly stringent environmental protection requirements, some Products are restricted in use, resulting in less selective medication

Embodiment 1

[0032] Add 5g of metconazole, 35g of dimethomorph, 6g of sodium lignosulfonate dispersant, 4g of diffusing agent NNO (sodium methylene bis-naphthalene sulfonate), 5g of white carbon black, and kaolin to 100g of the mixture for jet milling. A wettable powder with a weight percentage of 40% of the main active ingredient was obtained.

Embodiment 2

[0034] Add metconazole 10g, dimethomorph 30g, sodium lignosulfonate dispersant 6g, diffusing agent NNO4g, white carbon black 5g, kaolin to 100g mixture and carry out airflow pulverization, and the obtained main active ingredient weight percentage is 40 % wettable powder.

Embodiment 3

[0036] Add metconazole 15g, dimethomorph 25g, sodium lignosulfonate dispersant 6g, diffusing agent NNO4g, white carbon black 5g, kaolin to 100g mixture and carry out jet milling, and the obtained main active ingredient weight percentage is 40 % wettable powder.

Abstract

The invention discloses a bactericidal composition containing metconazole and dimethomorph and application thereof. The bactericidal composition uses the metconazole and dimethomorph as main effective components, wherein the weight ratio of the metconazole to the dimethomorph is (1-40):(1-90). The bactericidal composition can be used for preventing and treating diseases on cereal crops, vegetables and fruit trees, has higher synergic effect, overcomes and postpones the drug resistance of pathogenic bacteria, has the advantages of high bactericidal speed and longer duration time, lowers the use cost, and has obviously better preventing and treating effects than a single agent. The bactericidal composition can be used for preventing and treating fungus diseases on crops, especially can be used for preventing and treating rust, powdery mildew, leaf spot, glume blight, stalk rot, gray mold, downy mildew and other fungus diseases, and has better effect than a single agent.

Description

Technical field: [0001] The invention belongs to the field of pesticides, and relates to a bactericidal composition containing metconazole and dimethomorph and application thereof. Background technique: [0002] Metconazole (metconazole), chemical name: 5-(4-chlorophenyl)-2,2-dimethyl-1-(1,2,4-triazol-1-ylmethyl)-cyclopentanol , molecular formula: C 17 h 22 ClN 3 O, the chemical structural formula is as follows: [0003] [0004] Meconazole is a triazole fungicide, which is an inhibitor of C-14 demethylase in ergosterol biosynthesis. Although the mechanism of action is the same as that of other triazole fungicides, it is more active. Both of its isomers have fungicidal activity, but the activity of the cis form is higher than that of the trans form. Meconazole has a very broad fungicidal spectrum, high activity, and excellent preventive and therapeutic effects. Mainly used for the control of Septoria wheat, Fusarium paniculata, leaf rust, stripe rust, powdery mildew...
