Embodiment 1

[0040] Weigh 5% cyclopyrid, 20% buprofezin, 3% TERSPERSE 4894, 1% sodium lignosulfonate, 1% TERSPERSE 2500, 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% Silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), and deionized water were 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 25% epoxyclopyrid-buprofezin suspension concentrate.

[0041] The formula is used to prevent and control rice planthoppers. The dosage per mu is 30g, diluted with 50kg of water and sprayed. The control effect is 91.5% after 3 days and 93.6% after 14 days. 10% Cyclopyrid Suspending Concentrate 20g per mu and 25% Buprofezin WP 50g per mu are used in the same way, and the control effects after 3 days of medicine are 82.4% and 69.8% respectively. The control effects of days were 78.4% and 81.5%, respectively.

Embodiment 2

[0043] Weigh 5% cyclopyrid, 30% buprofezin, 4% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2020 (produced by Huntsman, USA), 0.2% magnesium aluminum silicate, 5% ethylene glycol , 0.5% formaldehyde, 0.5% silicone defoamer, deionized water 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 35% epoxyclopyrid-buprofezin suspension concentrate.

[0044] The formula is used to prevent and control cotton aphids. The dosage per mu is 30g, and the spray is diluted with 50kg of water. The control effect is 95.2% after 3 days and 96.6% after 7 days. 10% Cyclopyrid Suspending Concentrate 25g per mu and 25% Buprofezin WP 50g per mu are used in the same way, and the control effects after 3 days of medicine are 85.4% and 63.8% respectively, and 7 days after medicine. The control effects of days were 84.4% and 68.5%, respectively.

Embodiment 3

[0046] Weigh 10% cyclopyrid, 20% buprofezin, 3% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2020, 0.2% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone disinfectant Foaming agent, deionized water are added to 100% weight part. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% epoxyclopyrid-buprofezin suspension concentrate.

[0047] The formula is used to prevent and control wheat aphids. The dosage per mu is 15g, and the spray is diluted with 50kg of water. The control effect is 98.3% after 3 days of spraying, and 95.6% after 7 days of spraying. 10% Cyclopyrid Suspending Concentrate 20g per mu and 25% Buprofezin WP 40g per mu are used in the same way, and the control effects are 85.6% and 70.4% for 3 days after the medicine, and 70.4% after the medicine. The control effects of days were 83.7% and 80.2%.

Abstract

The invention discloses a pesticide composition containing cycloxaprid and buprofezin. The pesticide composition contains active components of cycloxaprid and buprofezin, wherein a weight ratio of cycloxaprid to buprofezin is in a range of (1: 20) to (20: 1). The pesticide composition can be prepared into an agricultural suspending agent, wettable powder, water dispersible granules, missible oil or dispersible oil suspending agent. The pesticide composition has the advantages that ingredients are reasonable; insecticidal effects are good; a use cost is low; activity and insecticidal effects are not produced by simple addition of activity of all the ingredients; compared with the existing single preparation, in addition to the good insecticidal effects, the pesticide composition has observable synergistic effects, slows down resistance generation, produces low preparation residue, has no pollution on crops and good safety, and meets safety requirements of pesticide preparations; and the pesticide composition has good control effects on rice planthopper, cotton aphid, wheat aphid and fruit tree scale insects.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing active ingredients cyclopyrid and buprofezin, and belongs to the technical field of compound pesticides. Background technique [0002] Cyclopyrid is a new neonicotinoid insecticide, chemical name: 9-(6-chloropyridin-3-yl)methyl)-4-nitro-8-oxa-10,11-di Hydrogen imidazo(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, planthoppers, whiteflies, flea beetles, c...
