Fluacrypyrim	Last updated: 23/01/2021
(Also known as: NA 83)

SUMMARY

Fluacrypyrim is an acaricide without EU regulatory approval for use. It has a low water solubility and is volatile. Little is known about its persistence in soils but it can be persistent in aquatic systems. It has a low level of toxicity to mammals. It shows a moderate to high level of toxicity to most aquatic species, earthworms and birds. It is not particularly toxic to honey bees.
