Imidacloprid 200 g/litre
The material shall consist of technical imidacloprid, complying with the requirements of FAO specification 582/TC (April 2006), dissolved in suitable solvents, together with any other necessary formulants. It shall be in the form of a clear or opalescent liquid, free from visible suspended matter and sediment, to be applied as a true solution of the active ingredient in water.
The formulation, after the stability test at 54ºC and following dilution with CIPAC standard water D and standing at 30 ± 2ºC for 18 h, shall give a clear or opalescent solution, free from more than a trace of sediment and visible solid particles. Any visible sediment or particles produced shall pass through a 45 μm test sieve.
Stability at 0 °C
After storage at 0 ± 2°C for 7 days, the volume of solid and/or liquid which separates shall not be more than 0.1 ml.
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 found before storage.
