Example Embodiment

[0127] Experimental example

[0128] According to the above-mentioned test method, the toxicities of the acaricidal compositions of different proportions were tested. The test results are shown in Table 1, Table 2, Table 3 and Table 4.

[0129] Table 1: Toxicity test results of different ratios of Acynonapyr and pyridaben against Tetranychus cinnabarinus

[0130] PharmacyLC 50(mg / L)

[0131] It can be seen from Table 1 that the ratio of Acynonapyr and Pyridaben at 15:1 to 1:15 has a synergistic effect on the control of Tetranychus cinnabarinus.

[0132] Table 2: Toxicity test results of Acynonapyr and etoxazole in different ratios to Tetranychus cinnabarinus

[0133] PharmacyLC 50(mg / L)

[0134] It can be seen from Table 2 that when the ratio of Acynonapyr and etoxazole is 10:1~1:10, there is a synergistic effect on the control of Tetranychus cinnabarinus.

[0143] Preparation example of acaricidal composition 1: 45% by weight Acynonapyr·pyridaben wettable powder

[0144] Acynonapyr original drug 5g, pyridaben original drug 40g, alkyl naphthalene sulfonate formaldehyde condensate (trade name: MorwetD425, Akzo Nobel) 9g, sodium lauryl sulfate (Aladdin reagent) 3g, kaolin ( Hangzhou Zuotu New Material Co., Ltd.) is added to 100g, pre-crushed and mixed uniformly, and then pulverized by a jet mill (Kunshan Unak Machinery Co., Ltd.) until the fineness meets the requirement of at least 98wt% to pass the 45μm test sieve, and the result is effective A wettable powder with a component mass content of 45% by weight.

Example Embodiment

[0145] Preparation example of acaricide composition preparation 2: 32wt% Acynonapyr·pyridaben wettable powder

[0146] Acynonapyr original drug 2g, pyridaben original drug 30g, lignosulfonate sodium salt (trade name: Ultrazine NA, Baolige Industrial Co., Ltd.) 10g, sodium lauryl sulfate (Aladdin reagent) 3g, kaolin ( Hangzhou Zuotu New Material Co., Ltd.) is added to 100g, pre-crushed and mixed uniformly, and then pulverized by a jet mill (Kunshan Unak Machinery Co., Ltd.) until the fineness meets the requirement of at least 98wt% to pass the 45μm test sieve, and the result is effective A wettable powder with an ingredient mass content of 32wt%.

Abstract

The invention belongs to the technical field of pesticides, and especially relates to an acaricidal composition and a preparation thereof, and an application of the acaricidal composition and the preparation. The effective components of the acaricidal composition comprise an active component A and an active component B; the effective component A is Acynonapyr, and the active component B is one ormore of pyridaben, etoxazole, spirodiclofen and fenpropathrin; a mass ratio of the active component A to the active component B is 80: 1 to 1:80, preferably 40:1 to 1:40, and more preferably 20:1 to 1:20; and the content sum of the active component A and the active component in the acaricidal composition is 5-80 wt%. The acaricidal composition or the preparation thereof has the advantages of effect enhancement, dosage reduction, prolongation of the lasting period, and delaying of the development of the pesticide resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an acaricidal composition and its preparation, and the application of the acaricidal composition and the preparation. Background technique [0002] Acynonapyr is a miticide newly developed by Japan Soda Company. It can be used to control harmful mites in fruits, vegetables and tea trees, and has no cross resistance with other miticides, which has important promotion significance. The CAS chemical name of Acynonapyr is (3-endo)-3-[2-propoxy-4-(trifluoromethyl)phenoxy]-9-[[5-(trifluoromethyl)-2-pyridine Base]oxyl]-9-azabicyclo[3.3.1]nonane (CAS: No.1332838-17-1), its structural formula is as follows: [0003] [0004] At present, pyridaben, etoxazole, spirodiclofen, and fenpropathrin are all commonly used insecticides / acaricides, and have good control effects on harmful mites in agriculture. [0005] Pyridaben is a pyridazine broad-spectrum acaricide with strong...
