Embodiment

[0066] Example: Combined toxicity test of pyrimaben and bifenazate in different proportions.

[0067] 1.1 Drugs to be tested

[0068] 98% of the original drug of pyrimaben and 96% of the original drug of bifenazate are provided by the R&D Department of Qingdao Hailier Pharmaceutical Co., Ltd.

[0069] 1.2 Test target

[0070] The test mites were collected from the test field of the Citrus Research Institute of the Chinese Academy of Agricultural Sciences. The cultivation and management conditions were the same. No pesticides had been applied recently. Leaves are kept for later use after 2 generations.

[0071] 1.3 single-dose determination method slide dipping method

[0072] Select female nymphs with the same individual size and bright red body color, and use a brush to stick the back of the test mite on the glass slide with double-sided adhesive tape. The concentration range of each slide is diluted. On the basis of the preliminary test, the two The original drug was...

Abstract

The invention relates to an acaricidal composition containing fluacrypyrim and bifenazate, and the acaricidal composition has the active ingredient prepared by binary compound of the fluacrypyrim and the bifenazate. The mass ratio between the fluacrypyrim and the bifenazate is 6:30, 9:27, 12:24, 15:21 or 18:18; in the preparation, the total mass of the fluacrypyrim and the bifenazate in the active ingredient accounts for 1-75% of the total mass of the whole preparation, and the rest components of the preparation are auxiliary components which are allowed to be used or accepted by pesticide. The compound pesticide composition can be made into pesticide formulations such as emulsion oil, suspending agent, wettable powder, water dispersible granules, emulsion in water and microemulsion. The acaricidal composition is mainly used for preventing red spiders of apples, citrus and grapes, tetranychus urticae and Mc Daniel mites of the apples as well as tetranychus urticae and Lewis mites of ornamental plants.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an acaricidal composition containing pyrimaben and bifenazate. Background technique [0002] Pyrimiden is the first methoxyacrylate acaricide developed by Nippon Soda Co., Ltd., developed by BASF. It has good contact killing and stomach poisoning effects, and is effective against various characteristics of harmful mites, including eggs, nymphs, and adults, and has good quick-acting and long-lasting effects. Control spider mites on citrus and apple trees. The chemical name of pyrimidin is methyl (E)-2-{α-[2-isopropoxy-6-(trifluoromethyl)pyrimidine-4-phenoxy]-0-tolyl}-3 -Methoxyacrylate, the chemical structure of which is . [0003] Bifenazate is a new type of selective foliar spray acaricide. Its mechanism of action is a unique effect on the GABA receptor of the central nervous system of mites. It is effective against various life stages of mites, has ovicidal...
