It may be difficult to imagine, but we receive more requests for information on pumpkin diseases and pumpkin disease control than on any other vegetable crop. Some of the requests arrive during the winter, when folks have had time to reflect on the previous season’s problems and are anxious to avoid similar problems during the next growing season. Unfortunately, most of the calls occur in August and September and are prompted by the “sudden” appearance of collapsed canopies or rotting fruit. Although some disease outbreaks are unforeseen, even by the keenest growers, most serious epidemics can be avoided by knowing which infectious diseases threaten the crop, recognizing their symptoms, and understanding how they spread and survive. This publication is designed to provide such information on the nature of several infectious pumpkin diseases.
