Leaf diseases pressure eases in 2016, insect damage showing

Most of Iowa was abnormally hot this growing season, causing insect and crop disease concerns over the state.

"Disease development is highly dependent on weather," said Alison Robertson, Iowa State University (ISU) Ex­­tension and Outreach field crops pathologist. "Northeast Iowa has been particularly wet, which favors many diseases. What’s different from previous years, though, is that temperatures are warmer."

She said disease risks are lower this year than they have been the past two years because of the predominantly drier-than-normal fields and above-average temperatures.
