Iowa has experienced two consecutive years with conditions very favorable for stalk rot development. Some producers have been realizing this over the last few weeks as they struggle to harvest fields that lodged due to stalk rot. The good news is that lodging is not as widespread this year as it was last year. According to Iowa Agricultural Statistics reports, about 19 percent of the acreage has moderate to severe lodging this year compared with last year when about 39 percent of the acres was reported to have moderate to severe lodging. This improvement, however, is probably not related to stalk rots; the light European corn borer pressure this year compared with last year has certainly made a difference.
