Active ingredient: FeHEDTA
Registration status: Registered by EPA’s Biopesticide division. PMRA registration expected December 09-January 10. Ontario approval expected 30-60 days later.
Mode of action/how it works: Iron toxicity. Fiesta is absorbed by the leaf tissue and translocated down to the root. As well, immediate toxicity of the contacted leaf tissue cells occurs turning the leaves black.
Broadleaf weeds are more sensitive to iron than turf.
Cuticle of certain broadleaf weeds more prone to Fiesta uptake.
