Crown rot, caused by Phytophthora blight, on squash plants, especially pumpkins, has been a growing problem in Illinois the past two growing seasons.
Squashes have numerous disease and insect pests, said a University of Illinois Extension horticulture educator.
"Phytophthora blight has been a serious problem on several other vegetable crops such as cucurbits, eggplants and peppers," said James Schuster. "In addition, in 2004, it was reported that beets, Swiss chard, lima beans, turnips and spinach were also susceptible to Phytophthora blight in some areas of the United States."
