HREZ Rootstock

Get rooted, protect your crop with HREZ rootstock!

With HREZ rootstock, you can ensure a healthier, more productive future for your tomato crops. HREZ rootstock (High resistance to ToBRFV) prevents the virus from spreading from the roots to the plant and decreases the overall virus pressure. This extra layer of defense, combined with HREZ varieties and effective phytosanitary measures, leads to fortified tomato plants.

Why use HREZ rootstock?

Stronger roots. Healthier plants. Higher yields.

Stronger defense

Blocks virus entry at the root & stops it from spreading further.


Vigour and yield

Enhances yield and ensures longer and healthier crop cycle


Long-term protection

By reducing the virus pressure, the risk of mutations decreases.

How does HREZ rootstock work?

HREZ rootstock provides extra protection by preventing infection right at the entry point, ensuring that the virus does not spread from the roots throughout the plant. The use of HREZ rootstocks significantly reduces virus pressure and improves crop yield. Numerous trials have demonstrated that it is possible to use HREZ rootstocks with non-HREZ varieties as well, since our defence mechanism acts from the root, reducing the multiplication of ToBRFV in the soil. Still, combining our HREZ varieties with HREZ rootstock represents the most effective strategy to protect tomato plants against the ToBRFV virus.

The ultimate defense: HREZ variety & HREZ rootstock

Utilizing both HREZ rootstock and HREZ variety is the most effective approach to safeguard tomato plants from ToBRFV. This powerful combination ensures comprehensive protection, with both the upper and lower parts of the plant shielded by the HREZ resistance mechanism.

✅Above-ground protection

✅Root protection

When ToBRFV comes into contact with the plant’s upper parts, the tomato triggers a hypersensitive reaction, causing affected cells to die quickly. This prevents the virus from spreading and multiplying, safeguarding the plant from further infection.

If the roots come into contact with ToBRFV - whether through soil or irrigation water - the HREZ rootstock isolates the virus right at the entry point. This approach prevents further infection of the root cells, reducing virus accumulation and spread, and lowering the overall virus pressure.
