Managing the Tomato Brown Rugose Fruit Virus (ToBRFV) in greenhouses in southeastern Spain requires a combination of preventive measures and the selection of varieties with strong genetic resilience. These should be integrated into production systems that uphold both quality and profitability. This key point was emphasized by Juan Miguel Agüero, Head of Product Development at BASF | Nunhems, during his talk at the World Tomato Congress 2026.

In his talk, titled "Beyond the rugose virus: integrating resistance, quality and profitability in tomato," Agüero emphasized the importance of addressing ToBRFV from a comprehensive, global perspective of the crop, particularly in highly specialized regions like Almeria and Murcia, where tomato remains a key economic driver.
The expert emphasized that the rugose virus is no longer a one-time issue but a structural factor influencing decision-making across the entire value chain. "Genetic resistance is a crucial tool, but it should not be considered alone; it must be paired with prevention, management, and a well-defined market strategy," he stated.

Prevention and genetics: The essential combination
Agüero emphasized that prevention remains the primary defense against the virus, achieved through strict biosecurity measures in seedbeds and farms. Nonetheless, he highlighted that these efforts should be supported by the development and adoption of resistant varieties that can ensure stable productivity in an environment that is becoming more challenging.
In this sense, BASF | Nunhems is developing breeding programs focused not only on resistance to ToBRFV but also on maintaining high levels of production, uniformity, flavor, and shelf life, key factors for the grower's competitiveness.
