Embodiment 1

[0046] Weigh 40% bifenazate, 8% abamectin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkylnaphthalene sulfonate formaldehyde Condensate), 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% parts by weight. The above raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulation steps to prepare 48% bifenazate·abamectin water-dispersible granules.

[0047] In this embodiment, the weight ratio of bifenazate and avermectin can be changed between (5-40): 1, and the total weight composition of the two is still 48%, forming a new embodiment.

Embodiment 2

[0049] Weigh 40% bifenazate, 4% abamectin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% by weight share. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulation to prepare 44% bifenazate·abamectin water-dispersible granules.

[0050] In this embodiment, the weight ratio of bifenazate and abamectin can be changed between (5-40): 1, and the total weight composition of the two is still 44%, forming a new embodiment.

Embodiment 3

[0052] Weigh 40% bifenazate, 1% avermectin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 4% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 5% K-12 (sodium lauryl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% by weight share. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultra-micro airflow pulverization, mixing, and granulation to prepare 41% bifenazate·abamectin water-dispersible granules.

[0053] In this embodiment, the weight ratio of bifenazate and abamectin can be changed between (5-40): 1, and the total weight composition of the two is still 41%, forming a new embodiment.

Abstract

The invention discloses an acaricidal composition containing bifenazate. Active ingredients comprise the bifenazate and propargite, and the weight ratio of the bifenazate to the propargite is (0.125-0.5): 1. The acaricidal composition has the advantages of being reasonable in components, good in acaricidal effect and low in medication cost, the activity and the insecticidal effect are not obtained by easy superposition of the activities of the components, the significant synergy is realized, and the acaricidal composition further has the effects of high rapid acting, long lasting effect, capability of slowing down the generation of resistance and good safety for crops, and is also can meet the safety requirements of pesticide preparations. The acaricidal composition disclosed by the invention can be used for preparing water dispersible granules, suspension concentrate, wettable powder, and missible oil or aqueous emulsion formulations so as to be used for controlling citrus red mites, European red mites and mites on cotton crops.

Description

Technical field [0001] The present invention involves a mite killing composition, which specializes in a phenylth ester as the first active ingredient. Avin, darted mites, or chiggamine is used as the second active ingredients and its applications.It belongs to the field of complex pesticide technology. Background technique [0002] Bifenazate in English, chemical molecular C 17 H 20 N 2 O 3 EssenceBenzylene is a γ-aminobutyric acid (GABA) antagonist. It mainly controls the leaf mites during the activity. It has good rapid efficiency. It has good effect on young mites and mites.Leaf mites have the effect of killing eggs.Experimental studies have shown that phenylped ester has no negative impact on predation mites; low toxicity on mammals (LD 50 It is 5000mg / kg); short -holding period in the environment (DT50 <1D).At present, the luminyl ester sold on the market is 480 grams / liter suspension, which is mainly used to prevent and control the red spider of apple trees.As a new pyr...
