Bonus myth — "With a resistant scion, you don’t need a resistant rootstock"

This myth is surprisingly persistent, and not by coincidence. If growers believe that a resistant scion makes a resistant rootstock unnecessary, the demand for specialized rootstocks drops dramatically. Some early industry messages reinforced this idea, often based on short trials that lasted only a few weeks. Those trials never captured what really matters: the long term viral pressure that builds up in the root zone. Debunking the myths around ToBRFV and HREZ In this series, our Senior Researcher Phytopathology Manus Thoen takes on the myths that spread just as fast as the virus itself. Together with experts from our breeding, diagnostics, pathology, and molecular biology departments, he unpacks common misconceptions about HREZ, Enza Zaden’s High Resistance to ToBRFV. Clear facts grow stronger than myths Strong decisions start with solid information. By combining what we know from breeding, research and agricultural practice, this series cuts through the noise and highlights what truly matters for managing ToBRFV in modern tomato production.
