Endothall (sodium salt)

Endothall is an aquatic plant growth regulator. It reduces curly leaf pondweed appearance frequency in and dry biomass from lakes when applied annually at a concentration of 1 mg/L. Endothall reduces leaf chlorophyll content in A. thaliana plants and root length in A. thaliana seedlings (IC50s = 1.36 mM and 13.9 µM, respectively) and decreases duckweed growth rate (IC50 = 10 µM).2 It induces production of ethylene in bean leaves when applied at a concentration of 1 µM.3 Endothall is also an inhibitor of protein phosphatase 2A (PP2A, IC50 = 19-50 nM).4 It is toxic to mice (LD50 = 5-50 mg/kg)..
