Problems solved by technology

[0004] However, due to the high price of trifloxystrobin technical, the shortcomings of single use are also prominent, and the cost of large-scale promotion and use by farmers is unbearable. Therefore, it is mostly in the form of compound preparations to further expand the bactericidal spectrum while reducing the cost of use. Improve efficacy
Due to its excellent control effect, tebuconazole has been widely used as a single-dose product, but the disadvantages of single-dose use are also prominent. Tebuconazole is also widely compounded with other products, which have the effect of synergistically improving drug efficacy
[0005] However, at present, there are relatively few compounds containing trifloxystrobin and tebuconazole, and the control effect is not ideal due to compounding technology.

Embodiment 1

[0047] A fungicidal composition wettable powder containing trifloxystrobin and tebuconazole is made of the following components by weight percentage:

[0048]

[0049] The preparation method of the above-mentioned fungicidal composition wettable powder containing trifloxystrobin and tebuconazole is as follows: sequentially add trifloxystrobin, the original drug of tebuconazole, auxiliary agents and carriers into the mixer for thorough mixing, start the jet mill, Ultrafine pulverize the preparation mixture, pass the inspection, and seal the package

[0050] The wettable powder of the fungicidal composition containing trifloxystrobin and tebuconazole is mainly used for preventing and treating diseases such as melons, vegetable powdery mildew, downy mildew, and wheat smut. When in use, according to the dosage of 7-15g / mu of the original drug, dilute 800 times with water, stir well, and spray on the leaves. Take the medicine once every 8-10 days, and use it twice in a row.

Embodiment 2

[0053] A bactericidal composition suspension containing trifloxystrobin and tebuconazole, made of the following components by weight percentage:

[0054]

[0055] A preparation method of a bactericidal composition suspension containing trifloxystrobin and tebuconazole is as follows: calculate the amount of all materials according to the ratio of the formula, mix wetting agent, dispersant, antifreeze, defoamer and 90% water Add it into the shearing kettle in proportion. After the dissolution is complete, add the trifloxystrobin and tebuconazole raw materials into the shearing kettle under the shearing state. After cutting evenly, enter the grinder for sand grinding until the particle size of the material reaches 3.5 μm. Requirements, sampling for content analysis, according to the analysis results, the thickener is dissolved in the remaining water and pumped into the shearing kettle, after the shear is uniform at a speed of 1000rpm, after the sampling test is qualified, the m...

Embodiment 3

[0059] A bactericidal composition suspension containing trifloxystrobin and tebuconazole, made of the following components by weight percentage:

[0060]

[0061] A preparation method of a bactericidal composition suspension containing trifloxystrobin and tebuconazole is as follows: calculate the amount of all materials according to the ratio of the formula, mix wetting agent, dispersant, antifreeze, defoamer and 90% water Add it into the shearing kettle in proportion. After the dissolution is complete, add the trifloxystrobin and tebuconazole raw materials into the shearing kettle under the shearing state. After cutting evenly, enter the grinder for sand grinding until the particle size of the material is 4 μm. Sampling is carried out for content analysis, and the thickener and remaining water are pumped into the kettle according to the analysis results. After the shearing is uniform, the sampling test is qualified, and the material is packaged.

Abstract

The invention discloses a sterilization composition containing trifloxystrobin and tebuconazole. The sterilization composition comprises trifloxystrobin and tebuconazole; the weight of the trifloxystrobin and the tebuconazole is 10-80% of the total weight of the sterilization composition; the weight ratio of the trifloxystrobin and the tebuconazole is (1-10): (1-10). The invention further discloses a wettable powder, a suspending agent and a water dispersible granule of the sterilization composition containing trifloxystrobin and tebuconazole, and a preparation method for the sterilization composition. The sterilization composition has the benefits as follows: (1) the trifloxystrobin and the tebuconazole are adopted as active ingredients; formula and content ratio of all preferred agents are optimized; bacteriocidal spectrum is remarkably expanded; the sterilization composition facilitates delaying generation of drug resistance of germs and prolonging service life of products; (2) the wettable powder, the suspending agent and the water dispersible granule are adopted as preferred schemes; production technologies are general pesticide preparation methods, and are low in technological difficulty, easy to apply, environmental-friendly, reasonable in preparation cost, simple to use, and high in product benefits.

Description

Technical field [0001] The invention relates to the field of pesticides, and in particular to a fungicidal composition containing trifloxystrobin and tebuconazole and a preparation method thereof. Background technique [0002] Trifloxystrobin is a new fluorine-containing fungicide and is considered a second-generation methoxyacrylate fungicide; due to its broad bactericidal spectrum, high efficiency and rapid effect, and resistance to rain erosion, it is effective against almost all fungal diseases. It has preventive and therapeutic effects, especially against powdery mildew and leaf spot. Trifloxystrobin is a mitochondrial respiration inhibitor and has no cross-resistance with existing fungicides. [0003] Tebuconazole is a highly efficient, broad-spectrum, systemic triazole fungicidal pesticide. It has three major functions: protection, treatment, and eradication. It has a broad bactericidal spectrum and a long-lasting effect. It can inhibit the biosynthesis of ergosterol...
