  • Patent number: 5665672
    Abstract: Fungicidal compositions for the protection of turfgrass against crown and root rot are disclosed. The compositions comprise, as the active material, a mixture of (a) a monoester salt of a phosphorous acid (preferably aluminum ethyl phosphite), and (b) an ethylene bisdithiocarbamate contact fungicide (preferably manganese-zinc ethylene bisdithiocarbamate). Preferred compsitions comprise one part by weight of the monosester salt to two parts by weight of the ethylene bisdithiocarbamate.

  • Patent number: 5580841
    Abstract: Disclosed are solid, phytoactive, N-phosphonomethyl-N-carboxymethyl compositions. Also disclosed are processes for the preparation of such compositions by(a) forming an initial mixture comprising a phytoactive N-phosphonomethyl-N-carboxymethyl compound, a solvent and a molten surfactant, the surfactant being solid at ambient temperatures;(b) removing solvent from the initial mixture to form a final mixture at a temperature above the melting point of the surfactant;(c) cooling the final mixture to a temperature below the melting point of the surfactant to form a N-phosphonomethyl-N-carboxymethyl composition which is solid at ambient temperatures; and(d) processing said composition into particulate form, such as pellets, flakes, granules, or powders.
