Embodiment 1

[0068] Weigh 60% etoxazole, 20% pyridaben, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% % Pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, and diatomaceous earth are added to 100% by weight. 80% etoxazole·pyridaben water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultrafine airflow pulverization, mixing, and granulation.

[0069] In this embodiment, the weight ratio of etoxazole and pyridaben can be changed between 30:1-1:50, and the total weight content of the two is still 80%, forming a new embodiment.

Embodiment 2

[0071] Weigh 45% etoxazole, 5% pyridaben, 3% TERSPERSE 2700, 3% sodium lignosulfonate, 2% pull open powder BX, 2% K-12, 3% white carbon black, 3% corn starch , 5% ammonium sulfate, and diatomaceous earth are added to 100% by weight. . 50% etoxazole·pyridaben water dispersible granules were prepared by the conventional method for preparing water dispersible granules from the above raw materials, ie mixing, ultra-fine airflow pulverization, mixing and granulation.

[0072] In this embodiment, the weight ratio of etoxazole and pyridaben can be changed between 30:1-1:50, and the total weight content of the two is still 50%, forming a new embodiment.

Embodiment 3

[0074] Weigh 60% etoxazole, 2% pyridaben, 5% sodium lignosulfonate, 4% diffusing agent NNO, 2% K-12, 3% white carbon black, 3% corn starch, 10% glucose, kaolin Add to 100% by weight. 62% etoxazole·pyridaben water-dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultrafine airflow pulverization, mixing, and granulation.

[0075] In this embodiment, the weight ratio of etoxazole and pyridaben can be changed between 30:1-1:50, and the total weight content of the two is still 62%, forming a new embodiment.

Abstract

The invention discloses an acaricidal composition containing etoxazole and pyridaben, wherein the weight ratio of the etoxazole to the pyridaben is (30:1) to (1:50), preferably (3:1) to (1:25), optimally (1:2) to (1:16). The composition can be prepared into water dispersible granule, suspending agent, oil dispersion suspending agent, wettable powder, missible oil, and emulsion in water or micro-emulsion. The invention is reasonable in component, good in acaricidal effect and low in pharmacy cost and has obvious synergy function, the activity and acaricidal effect thereof are not caused by simply mixing the components, the quick-acting property is high, the effective period is long, the resistance forming is slowed down, the safety to crop is high and the safety demand of pesticide preparation is met. The invention has better control efficiency of red spider to citrus, apple tree and cotton.

Description

technical field [0001] The invention relates to an acaricidal composition, in particular to an acaricidal composition containing etoxazole and pyridaben, which is used to prevent and control harmful mites in crops such as cotton, citrus, and apples, 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., the English common name: etoxazole, chemical formula C 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 excelle...
