Embodiment 1
[0063] Weigh 40% methoxyfenozide, 40% etofenprox, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, USA), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 1% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 3% soluble starch, 3% glucose, and kaolin are added to 100% by weight. 80% methoxyfenozide etofenprox water-dispersible granules are prepared by the conventional method for preparing water-dispersible granules from the above-mentioned raw materials, ie, mixing, micro-jet pulverization, mixing, and granulation.
Embodiment 2
[0065]Weigh 40% methoxyfenozide, 10% bifenthrin, 3% TERSPERSE 2700, 4% sodium lignosulfonate, 1% pull-off powder BX, 1% K-12, 1% carboxymethylcellulose , 3% urea, and diatomaceous earth are added to 100% by weight. 50% methoxyfenozide bifenthrin 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.
Embodiment 3
[0067] Weigh 50% methoxyfenozide, 5% lambda-cyhalothrin, 4% TERSPERSE 2700, 1% pull open powder BX, 1% K-12, 0.8% dextrin, 5% ammonium sulfate, attapulgite Add to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 55% methoxyfenozide-cyhalothrin water-dispersible granules.

Abstract
The invention discloses an insecticidal composition containing methoxyfenozide and etofenprox, bifenthrin or lambda-cyhalothrin synthetic pyrethroid insecticide. The weight ratio of the methoxyfenozide to the synthetic pyrethroid insecticide in the composition is 40:1-1:10, preferably 20:1-1:5. The insecticidal composition can be prepared into water dispersible granules, wettable powder, suspending agent, suspending emulsion, dispersible suspending agent, cream, microemulsion or microcapsule suspending agent. The insecticidal composition is used for preventing and controlling Chilo suppressalis, Tryporyza incertulas (walker), Cnaphalocrocis medialis Guenee, Helibthis armigera Hiibner, Adoxophyes orana and Laphygma exigua Hubner, and has the advantages of reasonable components, good insecticidal effect and low administration cost; and the activity and the insecticidal effect of the insecticidal composition are not simple superposition of the activities of the components but remarkable synergy, and the insecticidal composition can retard the generation of resistant, has good safety for crops and meets the safety requirement of pesticide preparations.
Description
technical field [0001] The present invention relates to an insecticidal composition, in particular, the first active ingredient is methoxyfenozide, and the second active ingredient is selected from etofenprox, bifenthrin or lambda-cyhalothrin pyrethroids The insecticidal composition of the insecticide belongs to the technical field of compound pesticides. Background technique [0002] Methoxyfenozide, English common name: methoxyfenozide, other English names: Intrepid, Runner, chemical name: N-tert-butyl-N′-(3-methyl-2-toluyl)-3,5-di Tolylhydrazine. Methoxyfenozide is a dihydrazide insecticide, an insect growth regulator, and a non-sterol-type ecdysone, which simulates the natural insect ecdysone-20-hydroxyecdysone, activates and attaches to The ecdysone receptor protein, prompts Lepidoptera larvae to enter the moulting process before maturity and fail to form a healthy new epidermis, thus causing the larvae to stop feeding early and eventually die. The response of Lepido...
