  • As water-dispersible granules (WG) or water-dispersible powders (WP) remain excluded. So far, only liquid formulations of phosphorous acid are used in practice, based on the potassium and / or sodium salts of phosphorous acid. These salts can not be satisfactorily formulated in solid form due to their high hygroscopicity.
  • certain agents eg. As dithiocarbamates, for chemical reasons in liquid formulation not permanently stable.
