| | Azide-metal salt formulations for control of fungi and nematodes - Patent 4132780 |
 | | The azides are hydrazoic acid, alkali metal azides, or alkaline earth metal azides and the metal salts are fluorides, bromides, chlorides, carbonates, sulfates, phosphates, nitrates, hydroxides, oxides, formates, acetates, propionates, oxalates, malates, citrates, butyrates, lactates, or tartrates of the metal ions: iron, aluminum, nickel, manganese (II), cobalt (II), zinc, tin (II), or magnesium. |
 | | A mixer is charged with 35 parts by weight of this sodium azide, 45 parts by weight of the zinc chloride particles, 15 parts by weight of potassium chloride particles, and 3 parts by weight of the potassium carbonate particles, and operated for 5 minutes to produce a thoroughly mixed blend of the dry particles. |
 | | Another procedure is to form in situ the soluble metal salt, such as magnesium chloride, or nitrate by dissolving in an acid solution such as hydrochloric acid, the metal itself or an insoluble salt of the metal such as oxide, carbonate, or hydroxide. |
