Problems solved by technology

[0009] In the prior art, there are cases where the two are used together with other active components, but the above two appear as secondary components, but there is no relevant report on the direct compounding of fluazinam and tetrafenazine. There is also no corresponding technical revelation to determine the effect of the combination of the two

Embodiment 1

[0024] The composition of fluazinam and tetrafenazine is a water emulsion, and the weight percentage of each component is: 20% fluazinam, 2% tetrafenazine, 10% cyclohexanone, 15% solvent naphtha S-150, 3% emulsifying Agent 601, 4% agricultural milk 600, 4% ethylene glycol, 0.4% magnesium aluminum silicate, and the balance is water; the weight percentage content of the active ingredients fluazinam and tetrafenazine in the fungicide and acaricide is 22% ; Add the active ingredient to the carrier, and add a surfactant to it to dissolve into a uniform oil phase, mix other functional additives with water to form a uniform water phase, and add the water phase to the In the oil phase, a well-dispersed water emulsion can be obtained.

Embodiment 2

[0026] The composition of fluazinam and tetrafenazine is a suspending agent, and the weight percentage of each component is: 35% fluazinam, 7% tetrafenazine, 4% formaldehyde condensate sulfate, 2% fatty amine polyoxyethylene ether, 1% Sodium Lauryl Sulfate, 0.1% Xanthan Gum, 1.5% Magnesium Aluminum Silicate, 3% Ethylene Glycol, 0.2% Defoamer, 0.1% Preservative, the balance is water, the active ingredients are Fluazinam and The weight percentage of tetrafenazine in the fungicide and acaricide is 42%. The above raw materials are mixed, dispersed by high-speed shearing for 15 minutes, wet sanded for 15 minutes, and finally homogeneously filtered to obtain the product.

Embodiment 3

[0028] The composition of fluazinam and tetrafenazine is a water-dispersible granule, and the weight percentage of each component is: 35% fluazinam, 35% tetrafenazine, 6% nonylphenol polyoxyethylene ether, 2% dodecane Sodium phenyl sulfonate, 4% naphthalenesulfonic acid formaldehyde condensate sodium salt, 1% penetrant T, and the balance is kaolin; the weight percent content of the active ingredients fluazinam and tetrafenazine in the fungicide and acaricide is 80% %; Mix the above raw materials, add 10-25% of water after jet crushing, and then knead, granulate, dry and sieve to obtain water-dispersible granules.

Abstract

The invention belongs to the field of pesticides, and particularly discloses an acaricidal composition of fluazinam and clofentezine. The active ingredients of the acaricidal composition are fluazinamand clofentezine, the weight ratio of fluazinam to clofentezine is 10:1 to 1:10, and the weight percentage content of the active ingredients namely fluazinam and clofentezine in the acaricide is 5-70%; and processing dosage forms are emulsifiable concentrate, microemulsion, suspending agent, water emulsion and wettable powder. The acaricidal composition provided by the invention has an obvious coordinating and synergistic effect, improves the prevention effect, and has an excellent control effect on pest mites of fruit trees, cotton, vegetables and ornamental plants; and meanwhile, the usageamount of pesticides is reduced, the pesticide cost is reduced, the pollution to the environment is reduced, and the generation of drug resistance of harmful mites is slowed down.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a pesticide compounding technology, in particular to an acaricidal composition of fluazinam and tetrafenazine. Background technique [0002] Fluazinam belongs to 2,6-dinitroaniline compounds, its chemical name is: 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α- Trifluoro-2,6-dinitro-p-toluidine, its molecular structural formula is as follows: [0003] [0004] It is a broad-spectrum and high-efficiency protective fungicide, which can prevent and control diseases caused by Botrytis cinerea. Specific diseases such as cucumber gray mold, rot, downy mildew, anthracnose, tomato late blight, apple scab, leaf spot, pear black spot, rust, rice mildew, sheath blight , Oat crown induced disease, grape gray mold, downy mildew, peanut scab and so on. At the same time, the study found that fluazinam has certain systemic properties, has a good killing effect on plant-eating mit...
