| European brown rot – Monilinia laxa (Aderh. & Ruhl.) Honey | ||||
| This rot is potentially serious on tart cherry cultivars Meteor, English Morello and Danube (Érdi bõtermõ) but rare on Montmorency. Wet periods lasting for a day or more are required for severe blossom infection and spur dieback. Newly infected blossoms and later spur leaves turn brown and shrivel. One- to 3-inch-long elliptical cankers, often with gummosis, are formed at the bases of blighted spurs. The fungus may produce tufts of ash-gray conidia on blossom debris, dead spurs and cankers in the second or third season after infection. Fruit infections are rare. | ||||
