Stone Fruit Rots Rampant In East

The incidents of fruit rots in both sweet and tart cherries and peaches and nectarines are quite high in Pennsylvania says Kari Peter of Penn State University Extension says in her latest report. Fungal spores have been spread around thanks to the extended warm, wet conditions.


“The amount of rain we have received has caused stone fruit to balloon making fruit skin weakened and cracked, thereby providing easier access for fungal spores. Cherries took a major beating this year with brown rot, as well as Alternaria rot,” she writes. “With such high spore pressure and optimal disease conditions, peaches and nectarines are under a significant threat of rot diseases as we are on the doorstep of harvest.”

Peter says there have been only four dry days in a row at the Fruit Research and Extension Center in Biglerville, PA.
