Embodiment

[0067] Example: Combined toxicity test of different ratios of pyrimaben and spirodiclofen.

[0068] 1.1 Drugs to be tested

[0069] 98% of the original drug of pyrimaben and 97% of the original drug of spirodiclofen are provided by the R&D Department of Qingdao Hailier Pharmaceutical Co., Ltd.

[0070] 1.2 Test target

[0071] 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.

[0072] 1.3 single-dose determination method slide dipping method

[0073] 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 wa...

Abstract

The invention relates to an acaricidal composition containing fluacrypyrim and spirodiclofen. The acaricidal composition is prepared by binary compounding of effective components, namely, fluacrypyrim and spirodiclofen in the mass ratio of 21: 33, 24: 30, 27: 27, 30: 24 or 33: 21; and the total mass of fluacrypyrim and spirodiclofen in the preparation is 1 to 80% based on the total mass of the whole preparation. The compounded acaricidal composition provided by the invention can be prepared into pesticide formulation like missible oil, suspension, wettable powder, water dispersible granules, emulsion in water and microemulsion. The acaricidal composition containing fluacrypyrim and spirodiclofen is mainly used for controlling pests such as red spider, yellow spider, phyllocoptruta oleivora ashmead, polyphagotarsonemus latus, tetranychus cinabarinus boisdu, tetranychus urticae koch, pear psylla, mussel scale and leafhopper, and can be used for controlling acarid on fruit trees such as orange trees and grape vines, and solanaceae such as eggplant, hot pepper and tomato.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an acaricidal composition containing pyrimaben and spirodiclofen. 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] Spirodiclofen has a new mechanism of action, with contact action and no systemic effect. It mainly inhibits the fat synthesis of mites and blocks the energy metabolism of mites. It is effective in all stages of development of mite...
