Hydrozone™ is a 100% active (no diluents as supplied) non-ionic residual wetting agent developed for use on sports turf to prevent localised dry patch (LDP) and give additional benefits in relation to the use and action of water. It has been carefully engineered for maximum performance giving long residence time and a highly effective wetting action.
LDP can arise from hydrophobic soil conditions which may in turn arise from plant breakdown material, animal sources, fungi and critically low soil moisture content. Hydrophobic soils can inhibit even distribution of water in the soil profile, denying grass roots an adequate supply of water, water soluble nutrients and applied treatments.
Hydrozone works by lowering the interfacial tension between water and other substrates (specifically soil constituents and grass roots) – this enables contact angles to be reduced and water to spread out laterally through the soil profile and flow into areas that were previously water repellent.
- Treatment and preventative for localised dry patch
- Contains a special surfactant to aid the initial spread into the rootzone
- Non-phytotoxic at use concentrations
- Non-scorch formula
- Excellent tank mix compatibility
- Potential to reduce water consumption where no turf wetter is currently used
- Assists in maximising the effectiveness of a range of soil chemicals and fertilisers
Properties
| Appearance | Clear viscous liquid at room temperature |
|---|---|
| Solidification point | Below minus 15⁰C |
| Viscosity | 600cP at 20⁰C |
| Maximum solubility | 5-8% over typical temperature range |
| Surface tension | 25 dynes/cm (3.5% solution in water) |
Hydrozone must be diluted in water prior to spray application. Hydrozone should be added to water rather than water added to Hydrozone – this avoids the potential for gel phases to form.
Hydrozone has widespread tank mix compatibility, however a jar test should be conducted first.
Monthly application – March/April until September/October:| Zone | Hydrozone | Water Volume | Area | Notes |
|---|---|---|---|---|
| Greens/Tees/Sports Pitches | 20 litres (preferred) 10 to 20 litres under conditions of low drought stress | 300-600 litres | 1 hectare | Do not exceed solution strength of 5%. Water in within 24/48 hours and before cutting to avoid reduced performance. |
| Fairways (golf) | 10-20 litres | 300-600 litres | 1 hectare | |
| Bowling Greens | 1.5-3 litres | 45-135 litres | 1,500m² |
90 day application – start March/April, repeat 90 days later:
| Zone | Hydrozone | Water Volume | Area | Notes |
|---|---|---|---|---|
| Greens/Tees/Sports Pitches | 50 litres | 1000 litres | 1 hectare | Do not exceed solution strength of 5%. Water in within 24/48 hours and before cutting to avoid reduced performance. |
| Fairways (golf) | 25-50 litres | 500-1000 litres | 1 hectare | |
| Bowling Greens | 7.5 litres | 150 litres | 1,500m² |
