| insect growth regulator | also known as mipubao, fly ethers, is a new type of insect growth regulator, developed by sumitom Chemical Industry Co., Ltd., the success of the role of the same insect juvenile hormone, with the inhibition of mosquitoes, flies larvae pupation and eclosion. The larvae of Mosquito and Fly exposed to the medicament were almost dead in the pupal stage and could not be feathered. The drug is effective for about 1 month, and easy to use, no smell, is a good mosquito, fly medicine. |
| control object of piripropyl ether | piripropyl ether is a phenylene ether insect growth regulator, which is a new insecticide of juvenile hormone analogs, it has the characteristics of endogenous transfer activity, low toxicity, long effective period, safety to crops, low toxicity to fish, and little impact on the ecological environment. It has a good control effect on Bemisia tabaci, Barbata, diamondback moth, beet armyworm, Spodoptera litura, pear wood lice, thrips, etc. At the same time, this product has a good control effect on flies, mosquitoes and other health pests. Can be used for the control of Homoptera, sinoptera, Diptera, lepidoptera pests. Its inhibitory effect on the surface of insects in the impact of Insect molting and reproduction. |
| toxicity | According to China's pesticide toxicity grading standards, piripropyl ether is a low toxicity insecticide. Acute oral LD50 >5 000mg/kg body weight in rats, acute percutaneous LD50 >2 000mg/kg body weight in rats, acute inhalation LC50 > 13 000mg/m3(4H) in rats. The eye has a slight irritation, no sensitization. No mutagenic or teratogenic reaction was observed at the experimental dose. Rats 6 months feeding test without the effect of dose 400mg/kg body weight, rats 28d inhalation test without the effect of dose 482mg/m3, animal absorption, distribution, rapid discharge. rat acute oral LD50>5000mg/kg, rat acute percutaneous LD50>2000mg/kg. |
| method of use | piripropyl ether is used to control mosquito, fly larvae and other health pests. Control of mosquito larvae, with 0.5% per cubic meter of piripropyl ether granules 20g (100mg) directly into the water (water depth of about 10cm is good); Control of housefly larvae, 20~40g (active ingredient 0.5% ~ 200mg) of 100 pyripropyl ether granules per cubic meter is scattered on the surface of housefly breeding site, which has a good inhibitory effect on mosquitoes and fly larvae. |
| note | 1. Store in a dark and cool place, away from fire. If the drug touches the skin, rinse thoroughly with soap and water. |
| Use | phenethers insect growth regulator, is the inhibitor of chitin synthesis of juvenile hormone type. It has the characteristics of high efficiency, low dosage, long effective period, safety to crops, low toxicity to fish and little impact on ecological environment. Can be used for the control of Homoptera, sinoptera, Diptera, lepidoptera pests. Its inhibitory effect on the surface of insects in the impact of Insect molting and reproduction. For Mosquito and Fly health pests, the late 4th instar larvae with low dose of this product will lead to the death of pupation stage, inhibit the formation of adults. When used, the granules are directly applied to the sewage pond or spread on the surface of Mosquito and Fly breeding sites. It can also control sweet potato whitefly and scale insect. The mosquito fly ether also has the activity of absorption and transfer, which can affect the larvae hidden on the back of the leaf. for the control of public health pests |
| production method | preparation of 4-bromodiphenyl ether with potassium hydroxide, copper powder and water, the reaction was pressurized at 245~250 ℃ for 16h, and then acidified, filtered, dried and distilled under reduced pressure to obtain p-hydroxydiphenyl ether with a yield of 81%. P-hydroxydiphenyl ether can also be prepared by the following method. Preparation of 1-methyl -2-(4-phenoxyphenoxy) ethanol with P-hydroxydiphenyl ether as raw material, 1-chloropropyl-2-ol, anhydrous potassium carbonate, DMF and phase transfer catalyst, it was prepared by reaction at about 75 °c for 24h. Synthesis of Mosquito and Fly ethers 1-methyl -2-(4-phenoxyphenoxy) ethanol was reacted with 2-chloropyridine in DMF as solvent in the presence of sodium hydride at room temperature to obtain Mosquito and Fly ethers for 24h. |
