Organism Group Effects Noted

No effects noted for this chemical. Try related chemicals.
 
Summary of Acute Toxicity for Organism Group

Sorry, no acute aquatic ecotoxicity data available for this chemical. Try related chemicals.
 

Terrestrial Ecotoxicity
Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
