Application

 

Ammonium sulfamate is applied in water solution or oil-water emulsion as a leaf, or foliar spray for control of woody plants, or it is applied as crystals or concentrated solution to cuts in the bark or on freshly-cut stumps of undesirable trees to prevent resprouting. It is used as a compost accelerator, flame retardant and in industrial processes.
