Break Viruses

Break viruses refer to virus-induced decline diseases of cherry causing severe fruit size reduction, altered coloration, poor flavor, and vigor loss. Little cherry disease significantly impacts cherry production, rendering fruit unmarketable. You'll see small, light-colored, poor-tasting fruit on infected trees. Spread by grafting infected wood and mealybug vectors. Purchase virus-tested planting material.

There is no cure for viral diseases. Remove and destroy infected plants to prevent spread to healthy ones nearby. Many viruses spread through insect vectors like aphids and leafhoppers, so managing those populations helps slow transmission. When replacing removed plants, choose virus-resistant varieties if available and purchase certified virus-free stock from reputable nurseries.
