Embodiment 1

[0067] Weigh 60% etoxazole, 20% bifenazate, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 2% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% by weight . 80% etoxazole·bifenazate water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0068] In this embodiment, the weight ratio of etoxazole and bifenazate can be changed between 30:1-1:60, 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-off powder BX, 2% K-12, 3% white carbon black, 3% can Dissolved starch, 5% ammonium sulfate, and diatomaceous earth are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 52% etoxazole·bifenazate water-dispersible granules.

[0071] In this embodiment, the weight ratio of etoxazole and bifenazate can be changed between 30:1-1:60, 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, and kaolin to 100% parts by weight. 36% etoxazole·bifenazate water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0074] In this embodiment, the weight ratio of etoxazole and bifenazate can be changed between 30:1-1:60, 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 harmful mites in cotton, citrus, apple and other crops, and belongs to the technical field of compound pesticides. Background technique [0002] Etoxazole is a brand-new acaricide with a special structure developed by Sumitomo Chemical Co., Ltd., English common name: etoxazole, chemical formula NC 21 h 23 f 2 NO 2 . Its mode of action is to inhibit the embryonic formation of mite eggs and the moulting process from larvae to adults. It is effective for eggs and larvae, but not for adults. Therefore, the best control time is the early stage of pest mite damage. This agent has strong rain resistance and the duration of effect is as long as 50 days. Use low doses. It is safe to the environment and has no or minimal harm to beneficial insects and beneficial mites. It has excellent control effect on citrus, cotton, appl...
