Embodiment 1
[0067] Weigh 60% etoxazole, 20% bifenazate, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkylnaphthalene sulfonate formaldehyde condensate), 2% pull powder BX (sodium dibutylnaphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 2% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% by weight . The above-mentioned raw materials are prepared by the conventional method of preparing water-dispersible granules, namely mixing, ultrafine jet pulverization, mixing and granulation to prepare 80% etoxazole·bifenazate water-dispersible granules.
[0068] In this embodiment, the weight ratio of etoxazole and bifenazate can vary between 30:1 and 1:60, and the total weight composition of the two is still 80%, forming a new embodiment.
Embodiment 2
[0070] Weigh 2% etoxazole, 50% bifenazate, 3% TERSPERSE 2700, 3% sodium lignosulfonate, 2% pull powder BX, 2% K-12, 3% white carbon black, 3% can Dissolved starch, 5% ammonium sulfate, and diatomaceous earth were added to 100% by weight. The above-mentioned raw materials are prepared by the conventional method of preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing and granulation to prepare 52% etoxazole·bifenazate water-dispersible granules.
[0071] In this embodiment, the weight ratio of etoxazole and bifenazate can vary between 30:1 and 1:60, and the total weight composition of the two is still 52%, forming a new embodiment.
Embodiment 3
[0073] Weigh 4% etoxazole, 32% bifenazate, 4% TERSPERSE 2700, 3% diffusing agent NNO, 2% K-12, 3% white carbon black, 3% corn starch, 10% glucose, kaolin and add to 100% by weight. The above-mentioned raw materials are prepared by the conventional method of preparing water-dispersible granules, namely mixing, ultra-fine jet pulverization, mixing, and granulation steps to prepare 36% etoxazole·bifenazate water-dispersible granules.
[0074] In this embodiment, the weight ratio of etoxazole and bifenazate can vary between 30:1 and 1:60, and the total weight composition of the two is still 36%, forming a new embodiment.

Abstract
The invention discloses a mite-killing composition containing etoxazole and bifenazate, wherein the weight ratio of the etoxazole to the bifenazate is (30:1)-(1:60), is preferably (10:1)-(1:25) and is more preferably (3:1)-(1:16). The composition can be prepared into a water dispersing particle, a suspension, wettable powder, a dispersible oil suspension, missible oil, an emulsion in water or a microemulsion. The mite-killing composition has reasonable component, good mite-killing effect and low cost of used medicines, achieves the activity and the mite-killing effect not by the simple superposition of all the components, and has obvious synergism. The mite-killing composition takes effect quickly, has long effect-holding period, delays the resistance production, is safe to crops, meets the safety requirement of a pesticide preparation, and has better effect of preventing and treating citrus tree, apple tree and cotton red spiders.
Description
technical field [0001] The invention relates to an acaricidal composition containing etoxazole and bifenazate, which is used for preventing and controlling pest mites in crops such as cotton, citrus and apple, and belongs to the technical field of compound pesticides. Background technique [0002] Etoxazole is a brand-new acaricide with special structure developed by Sumitomo Chemical Co., Ltd., the English common name: etoxazole, chemical formula NC 21 H 23 F 2 NO 2 . Its mode of action is to inhibit the embryo formation of mite eggs and the molting process from larvae to adult mites. It is effective for eggs and larvae, but not for adult mites. Therefore, the best control time is the early stage of the damage of mites. The agent has strong rain resistance and lasts for up to 50 days. Use low doses. It is safe to the environment and has no or minimal harm to beneficial insects and mites. It has excellent control effect on mites such as Tetranychus, Etylobacter mites...
