Embodiment 1

[0136] Weigh 10% cyclopyrid, 10% lambda-cyhalothrin, 3% TERSPERSE 4894, 1% TERSPERSE 2500, 2% diffusing agent NNO, 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5 % organosilicon defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare 20% cyclopyrid-cyhalothrin suspending agent.

[0137] The formula is used to prevent and control rice stem borer, the dosage per mu is 12g, diluted and sprayed with 45kg of water, the control effect is 92.4% after 7 days of application, and 94.5% after 14 days of application. The dosage of 10% cyclopyrid SC is 20g per mu and the dosage of 10% beta-cyhalothrin SC is 20g per mu. Using the same method, the control effect of 7 days after the medicine is respectively 82.62% and 78.81%. The control effects were 78.53% and 82.85% respectively 14 ...

Embodiment 2

[0139] Weigh 20% cyclopyrid, 2% beta-cypermethrin, 4% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2020, 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone Defoamer and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 22% epoxyclopyrid-beta-cypermethrin suspension concentrate.

[0140] The formula is used to prevent and control rice leaf roller, the dosage per mu is 6g, diluted and sprayed with 45kg of water, the control effect is 90.2% after 7 days of application, and 92.6% after 14 days of application. 10% cyclopyrid suspending agent per mu dosage 20g and 4.5% beta-cypermethrin emulsifiable concentrate per mu dosage 45g, use with the same method, the control effect of 7 days after the medicine is respectively 83.4% and 61.2%, after the medicine 14 days The control effects were 82.4% and 64.6%, respectively. The compo...

Embodiment 3

[0142] Weigh 20% cyclopyrid, 5% cypermethrin, 3% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2425, 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer 1. Add 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 a 25% epoxyclopyrid-cypermethrin suspension concentrate.

[0143] The formula is used to control rice and wheat aphids, the dosage per mu is 5g, diluted with 45kg of water and sprayed, the control effect is 98.3% after 7 days, and 95.6% after 14 days. 10% cyclopyrid suspending agent per mu dosage 20g and 10% cypermethrin emulsifiable concentrate per mu dosage 60g, use with the same method, the control effect of 7 days after the medicine is respectively 83.6% and 56.4%, the control effect of 14 days after the medicine The efficiency is 85.7% and 60.2% respectively. The synergistic effect of the combination of cyclopyrid and cypermethrin is...

Abstract

The invention discloses an insecticidal composition containing cycloxaprid and synthetic pyrethroid insecticides and application thereof. The effective active ingredients of the insecticidal composition include a first active ingredient which is cycloxaprid, and a second active ingredient selecting from synthetic pyrethroid insecticides such as high-efficiency cyhalothrin, high-efficiency cypermethrin, cypermethrin, biphenthrin, high-efficiency cyfluthrin, ethofenprox, silafluofen, fenvalerate and fenpropathrin, wherein the weight ratio of the first active ingredient to the second active ingredient is 1:100 to 100:1. The composition can be prepared into agriculturally acceptable water dispersible granules, wettable powder, suspension agent, dispersible oil suspension agent, micro capsule suspension agent, missible oil or micro emulsion. The insecticidal composition has reasonable components, good insecticidal effect and low administration cost, the activity and insecticidal effect of the composition are not simply superimposed effects of the activities of all the components; compared with the traditional single preparation, the insecticidal composition has both obvious insecticidal effect and obvious synergistic effect, can slow down the production of resistance, has the advantages of low residue, no pollution to crops and good safety and meets the requirement on safety of pesticide preparations.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition of cyclopyrid and pyrethroid insecticides, and belongs 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 ClN 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 effective against Lepidoptera pests. The dosage of this product is low, it is safe to the environment, and has little or no harm to beneficial organisms. It has high insecticidal activity against aphids,...
