Brown rot in tart cherry...

Danube cherry shoot afflicted with brown rot, 12-June, 2018. Photo by J. Clements, UMass. A particularly nasty case of brown rot has afflicted shoots of Danube and Balaton tart cherry at the UMass Orchard in Belchertown. It was confirmed as brown rot by Dan Cooley's lab, there was the thought it might bacterial canker, but that has been ruled out. Many shoots are afflicted and will have to be pruned out. Interestingly, we wonder if it is a case of European brown rot, which appears to be quite more virulent than the garden variety American brown rot. This outbreak emphasized the importance of timely bloom fungicide sprays, as this is when the brown rot infection got started. Fruits will have to be protected with fungicides when ripening too. For more information on European vs. American brown rot, see this article in Good Fruit Grower. And for timely fungicide application choices, see see the Cherries Spray Table in New England Tree Fruit Management Guide.
