Endosan Water Treatment

Last year we started using hydrogen peroxide as a water treatment method.

Using Endosan gave us the advantage of extending the period of time that hydrogen peroxide remains active in the water in low concentrations all the way down the irrigation lines and our capillary beds. The active ingredient, stabilised with silver ions, worked extremely well in high concentrations as an irrigation system cleaner.

The dosing system incorporates a high injector ratio pump, resistant to corrosive chemicals. Fine tuning the pump allows us to achieve the desired concentration, whether for shock treatment or in conjunction with a pulse meter for continuous treatment. The system is very easy to connect, maintain and adjust.

Unlike chlorine, hydrogen peroxide degrades quickly and doesn’t leave any residue, which makes it more environmental friendly. Its effectiveness is relatively unaffected by pH changes. Continuous dosing at low concentration doesn’t affect biological control. We didn’t notice any reduction of activity and effectiveness of Nemasys in our applications. Also, when hydrogen peroxide products degrade, oxygen is produced. That can be very beneficial for the plants when located in the root zone.

We can see the improvement in root condition of our overwintered production already.

We also noticed a significant decrease in leaf nematode activity. It is unclear yet how much we can credit to continuous treatment with hydrogen peroxide. Some researchers suggest that H₂O₂ has a direct and indirect effect on nematode eggs and hatched juveniles and boosts plant resistance to infection. We are still at the early stages of finding out.
