Etoxazole (Ref: S 1283)
Last updated: 16/02/2021
(Also known as: Yl 5301)

SUMMARY
A commonly used insecticide which currently has EU approval for use. It has a low aqueous solubility, a low volatility and, based on its chemical properties, would not be expected to leach to groundwater. It is non-mobile, not persistent in most soils but may be persistent in some water systems depending upon conditions. It not highly toxic to humans but is toxic to fish and aquatic invertebrates. It has a low toxicity to birds, honey bees and earthworms.
