Problems solved by technology

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

[0046] Example 1 80% epoxiconazole · carbendazim water dispersible granules

[0047] Epoxazole 25%, carbendazim 55%, dispersant polycarboxylate sodium salt 2.0%, sodium alkylphenol sulfonate 10%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 1.0 %, α-olefin sulfonate sodium 1.0%, fatty amide N-methyl taurine sodium salt 1.0%, disintegrant potassium chloride 1.04%, diammonium hydrogen phosphate 1.84%, ammonium nitrate 1.12%, ferrous sulfate 0.03 %, light calcium carbonate make up 100%, after the mixture is fully mixed evenly, carry out ultra-micro airflow pulverization to obtain 750 mesh fine powder, then add appropriate amount of water to the kneader and knead the obtained fine powder, and make it through a rotary disc granulator Granules were dried in a fluidized fluidized bed at 50°C to obtain 80% epoxiconazole·carbendazim water-dispersible granules.

Embodiment 2

[0048] Example 2 51.2% epoxiconazole·carbendazim water dispersible granules

[0049] Econazole 16%, carbendazim 35.2%, dispersant polycarboxylate sodium salt 2.0%, sodium alkylphenol sulfonate 10%, calcium lignosulfonate 1.0%, wetting agent a-sulfo fatty acid methyl ester 1.0 %, α-olefin sulfonate sodium 1.0%, fatty amide N-methyl taurine sodium salt 1.0%, disintegrant potassium chloride 1.04%, diammonium hydrogen phosphate 1.84%, ammonium nitrate 1.12%, ferrous sulfate 0.03 %, light calcium carbonate make up 100%, after the mixture is fully mixed evenly, carry out ultra-fine airflow pulverization to obtain 720 mesh fine powder, then add appropriate amount of water to the kneader to knead the obtained fine powder, and make it through the rotary disc granulator Granules were dried at 60°C in a fluidized fluidized bed to obtain 51.2% epoxiconazole·carbendazim water-dispersible granules.

Embodiment 3

[0050] Example 3 80% epoxiconazole · carbendazim water dispersible granules

[0051] Cycloconazole 25%, carbendazim 55%, dispersant alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 3.0%, wetting agent pull-off powder 1.0%, sodium alkylnaphthalene sulfonate 1.0%, disintegrant Ammonium sulfate 1.0%, sodium sulfate 0.1%, and talcum powder make up 100%. After the mixture is fully mixed, it is pulverized by ultra-fine airflow to obtain a 730-mesh fine powder, and the resulting fine powder is kneaded by adding an appropriate amount of water in a kneader. Granulate with a rotary disc granulator, and dry in a fluidized bed at 55°C to obtain 80% epoxiconazole·carbendazim water-dispersible granules.

Abstract

The invention discloses bactericidal composition. Effective components of the bactericidal composition include epoxiconazole and carbendazim, and weight ratio of the epoxiconazole to the carbendazim is 1-80:1-80. The invention further discloses application of the bactericidal composition. Mixing the epoxiconazole and the carbendazim is evidently synergistic, advantages of the same are given to effective play, the obtained bactericidal composition is excellent in quality and high in efficacy, diseases of powdery mildew of cucumber, grapevine anthracnose and the like can be prevented effectively, a preparation method of the bactericidal composition is simple, convenient to operate and low in energy consumption, drug dosage is reduced by the use of the mixed composition, drug resistance to a single drug by germs is delayed, and the bactericidal composition has high social and economic benefits.

Description

technical field [0001] The invention relates to a composition containing epoxiconazole and carbendazim and an application thereof, belonging to the technical field of pesticides. Background technique [0002] Carbendazim, English common name: carbendazim, chemical name: N-(2-benzoimidazolyl)-methyl carbamate, mainly used to prevent and control melon powdery mildew, blight, green onion, leek gray mold, eggplant, cucumber Sclerotinia, melons, bean anthracnose, pea powdery mildew, cruciferous vegetable gray mold, white spot, etc. Long-term single use of carbendazim is likely to make the bacteria resistant, and it is best to use it in rotation or in combination with other fungicides. good. [0003] Epoxiconazole, English name epoxiconazole, is a kind of systemic triazole fungicide, its active ingredient epoxiconazole inhibits the synthesis of ergosterol of pathogenic bacteria, hinders the formation of bacterial cell wall, and epoxiconazole molecule is effective to a kind of fun...
