This research examined how two major tomato pathogens – root-knot nematodes and Fusarium wilt fungus – interact and affect tomato plants with different resistance genes. The study found that while these pathogens can partially suppress each other’s reproduction, they cause much more severe plant damage when present together. This has important implications for tomato farming and disease management. Impacts on everyday life: – Helps farmers make better decisions about which tomato varieties to plant – Improves understanding of how to manage multiple plant diseases simultaneously – Contributes to developing more effective crop protection strategies – Supports efforts to reduce crop losses and maintain food security – Aids in breeding more resilient tomato varieties
