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.
Potato leafhopper (PLH) have arrived in Massachusetts, and pose a pest threat to young apple trees in particular. Scout for the presence of PLH in young apple planting and treat with an effective insecticide before they damage and stunt apple foliage on newly planted trees. PLH on older, bearing orchards do not present as much a threat.

Gypsy moth caterpillars are actively chewing foliage in orchards (where they occur) as can be seen here at the UMass Orchard in Belchertown. Do not be too complacent about gypsy moth, particularly young apple trees/new plantings. (They don't seem to bother stone fruit.) B.t. (Dipel, etc.) can be used to (eventually) control them, but must be used NOW when they are small, and it will take a while to work. Almost any petal fall insecticide (carbaryl, Imidan, etc.) will give quick knock-down and is highly recommended where they are doing a lot of chewing! For more information on gypsy moth, see the UMass Extension Landscape Message dated May 18, 2018. (Click on the Insects link.)

Current Bud Stages, UMass Cold Spring Orchard, Belchertown, MA. May 14, 2018
Pear psylla adults have become active egg layers with warm temperatures in Massachusetts pear orchards. These pictures of adults and eggs on pear buds were taken last week by Jaime Pinero in eastern Massachusetts. Early season psylla control beginning with oil sprays is essential for season-long management. For more information see:
