Septoria Leaf and Fruit Spot of Cucurbits
MetadataShow full item record
Zitter, Thomas A.
Septoria leaf and fruit spot, caused by the fungus Septaria cucurbitacearum, can be an important disease of certain cucurbits grown in the Northeast and Midwest. The fungus can infect the leaves of muskmelon, pumpkin, summer and winter squash (butternut, acorn, and processing “pumpkins” [actually squash]), and gourds and the fruit of pumpkin, butternut, acorn, and processing “pumpkins.” Although affected fruit are unlikely to rot in storage or to cause other fruit to rot, they may be unmarketable because of the raised white spots caused by the disease. The disease has occurred in New York since the early 1900s.
