Problems solved by technology

However, tetrafenazin has been used for a long time, and the resistance gradually increases. When the density of mites is high and the temperature is high, the effect is not ideal, and the quick effect is poor, and there is a defect that it is ineffective against adult mites.
[0006] At present, the pesticide preparations with bifenazate as the active ingredient are mainly 480 g / L bifenazate suspension concentrate. It has good resistance and high control effect on larvae, adults and nymphs, but its persistent effect is average, and its lethality to eggs is not large. Tetrafenazin acts on mite eggs and has a long-lasting effect, but its quick-acting effect is poor, and its effect on adult mites is poor. The mite is ineffective, the inventor accidentally found that the mixed use of bifenazate with fenbutatin or tetrafenazine can improve its quick-acting effect, and has a good duration of effect, slowing down the generation of pest resistance

Embodiment 1

[0025] Weigh 0.8% bifenazate, 50% fenbutyltin, 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 . 50.8% bifenazate · fenbutatin water dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, namely mixing, ultra-micro airflow pulverization, mixing, and granulation.

[0026] In this embodiment, the weight ratio of bifenazate to fenbutatin can be changed between 0.01-200:1, and the total weight composition of the two is still 50.8%, forming a new embodiment.

Embodiment 2

[0028] Weigh 40% bifenazate, 0.3% fenbutyltin, 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 . 40.3% bifenazate · fenbutatin water dispersible granules were prepared by the above-mentioned raw materials through the conventional method for preparing water-dispersible granules, ie mixing, ultra-micro airflow pulverization, mixing, and granulation.

[0029] In this embodiment, the weight ratio of bifenazate to fenbutatin can be changed between 0.01-200:1, and the total weight composition of the two is still 40.3%, forming a new embodiment.

Embodiment 3

[0031] Weigh 30% bifenazate, 30% fenbutyltin, 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 . 60% bifenazate · fenbutatin water dispersible granules are prepared by the conventional method of preparing water dispersible granules from the above raw materials, that is, mixing, ultrafine airflow pulverization, mixing, and granulation.

[0032] In this embodiment, the weight ratio of bifenazate and fenbutatin can be changed between 0.01-200:1, and the total weight content of the two is still 60%, forming a new embodiment.

Abstract

The invention discloses a bifenazate-containing insecticidal composition. Active components comprise bifenazate and clofentezine, wherein the weight ratio of the bifenazate to the clofentezine is 0.01-200:1, preferably 0.2-20:1. The composition is advantageous in that the composition has reasonable components, good insecticidal effects and low drug-using cost; activity and insecticidal effects of the composition are not simply addition of activity of each component but have remarkable synergy effects; the composition has high rapid-acting property and long effect persistence; the composition slows down generation of resistance; and the composition is good to crop safety, and meets safety requirements of pesticide preparations. The control efficiency of the composition for citrus red mites, apple red mites, and mites on cotton crops reaches 86.65%-96.38%.

Description

[0001] The patent application of the present invention is a divisional application of the patent application 20091010 with the name of invention and creation named as an insecticidal composition containing bifenazate, the application number is 200910205340.7, and the filing date is 20091010. technical field [0002] The invention relates to an insecticidal composition, in particular to an insecticidal composition comprising bifenazine as the first active ingredient, fenbutatin or tetrafenazine as the second active ingredient and its application, which belongs to compound Pesticide technology field. Background technique [0003] 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. La...
