Clothianidin (Ref: CGA 322704)
Last updated: 17/08/2021
(Also known as: Tl 435; HSDB 7281; thiamethoxam metabolite)

SUMMARY
Clothianidin is an insecticide for the control of sucking and chewing pests. It is moderately soluble and volatile but has a high potential for leaching to groundwater. It is very persisent in soil and water. Risk of bioaccumulation is low and its acute toxicity to mammals is considered moderate. It is, however, a nurotoxicant. It is toxic to some aquatic organisms but not greatly so to fish. It is highly toxic to honeybees but low risk to earthworms.
