(Also known as: kanemite) |
SUMMARY |
Acequinocyl is an acaricide that is currently being evaluated for EU use. It is not highly soluble in water but is highly soluble in most organic solvents. It is volatile. It is not expected to leach to groundwater. It is not mobile and tends not to be persistence in soil or aquatic systems. It has a low mammalian toxicity and there is some concern regarding its potential for bioaccumulation. Acequinocyl is moderately toxic to birds, fish, honeybees and earthworms and highly toxic to aquatic invertebrates. |
