Embodiment 1

[0053] Taking by weighing mass percent is 40% bifenazate, 8% abamectin, 3% TERSPERSE 2700 (polycarboxylate, produced by U.S. Huntsman Company), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde Condensate), 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium dodecyl sulfate), 3% white carbon black, 5% ammonium sulfate, diatomaceous earth added to 100% parts by weight. 48% bifenazate·abamectin 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.

[0054] In the present 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 48%, forming a new embodiment.

Embodiment 2

[0056] Weigh 40% bifenazate, 4% abamectin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 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. 44% bifenazate·abamectin water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0057] In the present 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

[0059] Weigh 40% bifenazate, 1% avermectin, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 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. 41% bifenazate·abamectin water-dispersible granules were prepared by the conventional method for preparing water-dispersible granules from the above raw materials, ie, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0060] In the present 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 41%, forming a new embodiment.

Abstract

The invention relates to an acaricide compound containing biphenyl hydrazine ester. The weight precentage ratio of the first active ingredient: biphenyl hydrazine ester and the second active ingredient: abamectin, pyridaben or propargite of the compound is (5 to 40): 1, (0.5 to 8):1, (0.125 to 0.5):1. The acaricide compound can be prepared into water dispersed particle agent, suspending agent, wettable powder, missible oil or aqueous emulsion. The compound can be applied to the citrus red mite, European red mite and mite on cotton plants. The component is reasonable, the mite killing effect is obvious and the manufacturing cost is low. With quick acting property and long lasting effect, the activity and the disinfectant effect of compound are obviously beneficiated, can slow down the generation of resistance, are safe to plant and meet the safety demand of agricultural chemical preparation.

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 gamma-aminobutyric acid (GABA) antagonist, which mainly controls active spider mites. It has good quick effect and is effective against larvae, adults and nymphs. 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 5000mg / kg); short duration in the environment (DT50<1d). Currently, bifenazine sold in the market is a suspension concentrate of 480 grams per liter, which is mainly used to pr...
