Propiconazole 250 g/kg
The material shall consist of technical propiconazole, complying with the requirements of FAO specification 408/TC/S/F (1993), dissolved in suitable solvents together with any other necessary formulants. It shall be in the form of a stable liquid, free from visible suspended matter and sediment.
After the heat stability test the product, when diluted at 30°C with CIPAC Standard Waters A and C, shall comply with the following:
Time after dilution Limits of stability
0 h Initial emulsification expressed as 100%
0.5 h Minimum 70%
2.0 h Minimum 50%
24 h* Re-emulsification 100%
24.5 h* Minimum 50%
In special cases a test using CIPAC Standard Waters A and C before the heat stability test may be necessary.
*This test needs only to be carried out in case of doubt as to the result of the 2-hour emulsion stability test.
Stability at 0 °C
After storage at 0 ± 1°C for 7 days, no solid or liquid shall separate.
After storage at 54°C ± 2 °C for 14 days, the determined averaged active ingredient content must not be lower that 97% relative to the determined average content before storage and the product shall continue to comply with pH range.
