Phenylethers are insect growth regulators, which are inhibitors of chitosan synthesis of juvenile hormone type. It has the characteristics of high efficiency, low dosage, long duration, safety to crops, low toxicity to fish and little impact on ecological environment. It can be used to control homoptera, thysanoptera, diptera, lepidoptera pests. Its inhibitory effect on insects is apparent in affecting insect molting and reproduction. For mosquito and fly health pests, low dose of this product can cause death at the pupation stage and inhibit the formation of adult larvae. When used, the granules should be applied directly to sewage ponds or scattered on the surface of mosquito and fly breeding areas. It can also control sweet potato whitefly and scale insect.

Usage method
Pyriproxyfen is used to control mosquitoes, fly larvae and other health pests. To control mosquito larvae, 20g of 0.5% pyriproxyfen granules (effective ingredient 100mg) per cubic meter should be directly injected into water (water depth of about 10cm is good); For the control of housefly larvae, 20 ~ 40g(effective ingredient 100 ~ 200mg) of 0.5% pyriproxyfen granules per cubic meter was applied to the surface of the breeding ground of housefly, which had a good inhibition effect on mosquito and fly larvae.
