Preventing roots from clogging your drippers

RootGuard Band®

Metzer’s RootGuard Band® is a patented, field-proven solution for preventing roots intrusion in subsurface drip irrigation (SDI) systems. Developed in collaboration with GeoFlow USA, the RootGuard Band® releases a root-inhibiting agent directly from the dripline—ensuring years of uninterrupted irrigation performance. This innovation is ideal for long-term installations across orchards, vineyards, and field crops, including systems using treated wastewater. With over 25 years of success worldwide, Metzer’s RootGuard Band® redefines durability and peace of mind for growers.

Slow release with every drop

The RootGuard Band® is implemented into the dripline as an internal third-layer. Its position in the upper part of the dripline just above the dripper’s outlet — insures that the active substance is effectively released to the roots zone with every drip of water that emerges from the dripper.
