preparation Embodiment

[0017] The content of the present invention will be further described below in conjunction with the examples, and the active ingredient in the formulation examples is the weight after 100 percent.

[0018] Formulation Example 1 41% Valifenalate·fenpyrazamine Suspension Concentrate

[0019] Weigh 1% fenpyrazamine, 40% Valifenalate, 7% phenylphenol polyoxyethyl ether phosphate, 3% alkylnaphthalene sulfonate, 0.8% silicone, 1% sodium benzoate, 0.8% ethylene glycol, gum arabic 2%, make up to 100% with water. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 A 41% fenpyrazamine·valifenalate suspension concentrate was prepared after being less than 10 microns.

Embodiment 2 2

[0020] Preparation Example 2 22% Valifenalate·fenpyrazamine EC

[0021] Weigh 2% fenpyrazamine, 20% Valifenalate, 7% calcium dodecylbenzenesulfonate, 2% fatty alcohol polyoxyethylene ether, 2% castor oil polyoxyethylene ether, and vegetable oil to 100%. Mix active ingredients of pesticides, co-solvents, emulsifiers, and solvents in proportion, and mix and stir in the preparation kettle. After completely dissolving, slowly add the remaining solvent, and get a uniform oil phase after fully stirring to make 22% Valifenalate·fenpyrazamine EC.

Embodiment 3 6

[0022] Preparation Example 3 36% Valifenalate·fenpyrazamine water dispersible granules

[0023] Weigh 20% fenpyrazamine, 16% Valifenalate, pull open powder 7%, sodium lauryl sulfate 3%, citric acid 7%, polyvinyl alcohol 6%, borax 1%, diatomaceous earth 18%, kaolin make up to 100g , mix the pesticide active components, additives and fillers in proportion, pulverize by airflow, then add 15-20% water, knead, granulate, dry and sieve to prepare 36% Valifenalate·fenpyrazamine water-dispersible granules.

[0024] Preparation Example 4 21% Valifenalate·fenpyrazamine Suspension Concentrate

[0025] Weigh 8% fenpyrazamine, 13% Valifenalate, 7% TERSPERSE2020, 6% benzyl xylenol polyoxyethyl ether, 5% alkylaryl polyoxyethylene polyoxypropylene ether, 2% polyvinyl alcohol, 0.8% glycerin , 12% cyclohexanone, turpentine-based vegetable oil complemented to 100%. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90...

Abstract

The invention relates to a bactericidal composition containing Valifenalate and fenpyrazamine, wherein the weight ratio of two effective components is (1 to 40) to (40 to 1), the weight percent of theeffective components in a bactericide is 1 to 90 percent, preferably 5 to 80 percent and the balance of allowable additives and carriers in the pesticide. The composition disclosed by the invention has the advantages of obvious synergistic effects, capability of reducing the use amount of the pesticide, environment friendliness and safety.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide composition containing Valifenalate and fenpyrazamine. Background technique [0002] Valifenalate is a dipeptide fungicide, which has good effect on various mold diseases, and has been approved for registration for high-value economic crops, such as grapes, tomatoes, and other vegetables. [0003] [0004] Fenpyrazamine is a new type of pyridine heterocyclic fungicide developed by Sumitomo Chemical Co., Ltd., Japan. It has a novel chemical structure, can quickly penetrate into crops, and can quickly exert its drug effect on infected fungi. Tests have shown that fenpyrazamine is effective against sclerotinia, Streptococcus and Pseudocercospora showed high activity. It is mainly used to control Botrytis cinerea in protected crops. Its mechanism of action is to inhibit fungal ergosterol biosynthesis, which can inhibit mycelium growth, spore germination and pollen...
