Embodiment 1

[0056] Weigh 10% cyclopyrid, 10% chlorpyrifos, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 2% diffusing agent NNO, 0.3% xanthan gum , 5% propylene glycol, 3% triphenyl phosphate, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), deionized water 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 20% epoxyclopyrim·chlorpyrifos suspension.

Embodiment 2

[0058] Weigh 5% cyclopyrid, 15% triazophos, 1% diffusing agent NNO, 3% Nongru 700#, 2% Nongru 1601#, 2%TERSPERSE 2500, 0.3% xanthan gum, 5% propylene glycol, 3% triphenyl phosphite, 0.5% benzoic acid, 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 sanded with a sand mill to prepare a 20% epoxyclomid·triazophos suspension concentrate.

Embodiment 3

[0060] Weigh 2.5% cyclopyrid, 32.5% chlorpyrifos, 6% calcium lignosulfonate, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 25% white Carbon black, 2% triphenyl phosphate, and kaolin are added to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 35% cyclopyrid-chlorpyrifos wettable powder.

Abstract

The invention discloses an insecticidal composition containing epoxy insect pyridine and organic phosphorus insecticide. The organic phosphorus insecticide is selected from chlorpyrifos, triazophos and panaplate; and the weight ratio of the epoxy insect pyridine to the organic phosphorus insecticide is 1:60 to 60:1. The composition can be prepared into agriculturally allowed formulations such as water dispersible granules, wettable powder, suspending agents, dispersible oil suspending agents, microcapsule suspensions, missible oil or microemulsion. The insecticidal composition has reasonable components, a good insecticidal effect and low pesticide using cost; the activity and the insecticidal effect of the composition are not the simple superposition of the activity of each component; compared with a conventional single preparation, the composition has remarkable synergy besides a remarkable insecticidal effect, slows the generation of resistance, has low preparation residual amount, high safety and no pollution to crops, and meets the requirement for the safety of a pesticide preparation. The composition has good prevention and control effects on pests such as wheat aphids, cotton bollworms, phyllotreta striolata, cnaphalocrocis medinalis, rice planthoppers and the like.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing cyclopyrid and organophosphorus 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 ...
