    • Description
    • The formulation shall consist of an emulsion of technical tebuconazole, complying with the requirements of FAO specification 494/TC/S/F (2000), in an aqueous phase together with suitable formulants. After gentle agitation the product shall be homogeneous and suitable for dilution in water.

    • PH Range
    • pH range: 6.0 to 9.0
    • Pourability
    • "Rinsed residue": maximum 0.5 %
    • Wet sieve test  
    • Maximum: 0.5 % retained on a 75 µm test sieve.
    • Emulsion stability and re-emulsification   
    • After the heat stability test), the product, when diluted at 30 °C ± 2°C with CIPAC Standard Waters A and D, shall comply with the following:


      Time after dilution    Limits of stability
      0 h   :   Initial emulsification complete

      0.5 h   : "Cream", maximum: 0 mL

      2.0 h   :  "Cream", maximum: 1 mL
      "Free oil", maximum: 0 mL

      24 h*   : Re-emulsification complete

      24.5 h*  : "Cream", maximum: 0 mL

      "Free oil", maximum: 0 mL

      In special cases, a test using CIPAC Standard Waters A and D before the heat stability test may be necessary. Alternatively, if the buyer requires other CIPAC Standard Waters to be used, than this shall be specified when ordering.


      *These tests need only be carried out in case of doubt as to the emulsion stability result of the 2 hour test.
    • Persistent foam
    • Maximum: 25 mL after 1 min.
    • Storage stability
    • Stability at 0°C
    • After storage at 0 ± 2 °C for 7 days, the product shall comply with Wet sieve test. No separation of oily matter shall be visible after gentle agitation.

    • Stability at elevated temperature
    • After storage at 54 ± 2°C for 14 days, the determined average active ingredient content must not be lower than 97 % relative to the determined average content before storage and the product shall continue to comply with Pourability, Wet sieve test and, if relevant, pH range.
