Embodiment 1
[0031] Weigh 1% cyclopyrid, 2% fipronil, 1% TERSPERSE 2700, 1% TERSPERSE 2500 (produced by Huntsman, USA), 3% TERSPERSE 4894 (produced by Huntsman, USA), 2.0% polyethylene Pyrrolidone, 0.2% xanthan gum, 5% ethylene glycol, 0.3% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 1% rose bengal, deionized Water is added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 3% epoxyfenpyr-fipronil suspension seed coating agent.
Embodiment 2
[0033] Weigh 10% cyclopyrid, 5% fipronil, 3% TERSPERSE 4894, 2% TERSPERSE 2500, 1% TERSPERSE 2020 (produced by Huntsman, USA), 3% hydroxypropyl methylcellulose, 0.5% Bentonite, 5% ethylene glycol, 0.3% sodium benzoate, 0.5% organic silicon defoamer, 3% rose bengal, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 15% epoxyfenpyr-fipronil suspension seed coating agent.
Embodiment 3
[0035] Weigh 9% cyclopyrid, 9% butylene fipronil, 3% TERSPERSE 4894, 1% alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, 1% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% polyvinyl acetate, 0.2% xanthan gum, 5% propylene glycol, 0.3% benzoic acid, 0.5% silicone defoamer, 3% rose bengal, and deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 18% epoxyclopyr-butene fipronil suspension seed coating agent.

Abstract
The invention discloses an insecticidal composition containing cycloxaprid and a pyrazole insecticide. The active ingredients of the insecticidal composition are a first active ingredient cycloxaprid and a second active ingredient pyrazole insecticide which is selected from Fipronilm, butene-fipronil and Ethiprole, and the weight ratio of the first active ingredient to the second active ingredient is (1:20)-(20:1). The composition disclosed by the invention can be prepared into preparation formulation acceptable agriculturally such as a flowable concentrate for seed coating, a seed treatment dispersible powder, a seed treatment dispersible granule. The composition has reasonable components, good insecticidal effect, low application cost, and the activity and the insecticidal effect of the insecticidal composition are not the simple superposition of the activities of the components; compared with the conventional single preparation, besides the obvious insecticidal effect, the composition has obvious synergistic action and good safety, accords with the safety requirement of the insecticide preparation, and has good preventing and controlling effect on subterranean pests of crops.
Description
technical field [0001] The present invention relates to an insecticidal composition, especially a kind of insecticide containing cyclopyrid as the first active ingredient, and a pyrazole insecticide selected from fipronil, butene fipronil and ethiprole as the second active ingredient. The invention discloses an insecticidal composition with two active ingredients, belonging to the technical field of compound pesticides. Background technique [0002] Cyclopyrid is a new neonicotinoid insecticide, created by East China University of Science and Technology, chemical name: 9-(6-chloropyridin-3-yl)methyl)-4-nitro-8-oxa -10,11-dihydroimidazo(2,3-a)bicyclo(3,2,1)oct-3-ene, English common name: cycloxaprid, chemical formula C 14 h 15 CIN 4 o 3 . It has systemic, stomach poisoning and contact killing effects on pests, and can be used to control Homoptera and Coleoptera pests on crops. It has no cross-resistance with imidacloprid, acetamiprid, thiamethoxam, etc., and is also effe...
