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. The active components of the acaricidal composition include bifenazate and pyridaben, wherein the weight ratio of the bifenazate to the pyridaben is (0.5-8):1. The acaricidal composition has reasonable components, good acaricidal effect and low medication cost; the activity and insecticidal effect thereof are not a simple superposition of the activity of each component but an obvious synergic effect; and the acaricidal composition has high effect taking speed and long persistence, delays the generation of resistance, is very safe to crops, and conforms to safety requirements for pesticide preparations. The acaricidal composition disclosed by the invention can be prepared into water dispersible granules, suspending agent, wettable powder, missible oil or emulsion in water, thereby being used for preventing and controlling the panonychus citri, panonychus ulmi and acarid on cotton crops.

Description

technical field [0001] The present invention relates to an acaricidal composition, in particular to an acaricidal composition in which bifenazate is used as the first active ingredient, and abamectin, pyridaben or propargite is used as the second active ingredient, and its application. It belongs to the technical field of compound pesticides. Background technique [0002] Bifenazate English common name bifenazate, chemical formula C 17 h 20 N 2 o 3 . Bifenazate is a γ-aminobutyric acid (GABA) antagonist, which mainly controls active spider mites. It has good quick effect and has good effect on larvae, adults and nymphs. It is also effective against some other mites, especially Erspot Spider mites are ovicidal. Experimental studies have shown that bifenazate has no negative effects on predatory beneficial mites; it has low toxicity to mammals (LD 50 5 000mg / kg); short duration in the environment (DT50<1d). Currently, bifenazine sold in the market is a suspension c...
