Prosulfuron (Ref: CGA 152005)
(Also known as: proszulfuron)
SUMMARY
Prosulfuron is a broad-spectrurm herbicde. It is highly soluble in water and many organic solvents, is volatile, mobile and has a high potential for leaching to groundwater. It is generally moderately persistent in soil systems but can ve very persistent in aquatic systems. It is moderately toxic to mammals but is not expected to bioaccumulate. It is moderately toxic to birds, honeybees, earthworms and fish but less so to aquatic invertebrates. It is highly toxic to algae and aquatic plants.
