- Starting dose: 5 litres Blue Bac-2 / ha.
- Follow-up dose: 5 litres Blue Bac-2 / ha.
For serious contamination
If the pipes are seriously contaminated, clean them with hydrogen peroxide (H2O2) prior to administering the first dose. Then clean the filters and flush out the pipes. Do not apply the first dose of Blue Bac-2 until this has been done.
For limited contamination
When there is just a limited degree of contamination, the initial dose can be administered immediately. Even in this situation, there is a high chance that the filters are clogged. Clean them, then flush out the pipes. Once this is done, begin the dripping. Once the pipes are clean, Blue Bac-2 will keep them clean and will boost root development.
Both the starting and the follow-on doses can be delivered in the morning in a single shot from a separate suction box. The dose can also be administered continuously, from the A box or working stock. In addition, use a Venturi, waterfall or Nanobubble to ensure that the water is well aerated. In the event of a long-term break in irrigation, for example during the winter period, blow through the pipe system first before applying Blue Bac-2. Do not use Blue Bac-2 in water to which hydrogen peroxide (H2O2), chloride or another disinfectant has been added. These will cause Blue Bac-2 to break down and it will not have an impact.
