Reminder: Weed Science Field Day at Urbana
Come to Urbana on July 8 for the University of Illinois Weed Science Field Day.
Reminder about Corn Size and Postemergence Herbicides
Most postemergence corn herbicide labels warn of corn injury if the product is applied beyond a particular corn size or development stage. Also, be cautious in applying growth regulator herbicides during periods of rapid growth and stem elongation.
Conditions Favorable for Phytophthora Root and Stem Rot on Soybean
With the high amounts of rainfall received throughout Illinois, Phytophthora root and stem rot is likely to be seen more often this year.
Soybean Planting Delays Continue
As producers approach very late single-crop planting, recommendations start to follow those for double-cropped soybean.
Nitrogen Applications Over the Top
The season’s prolonged wet conditions are leaving growers with no other alternative than sidedress applications for nitrogen.
Too Hot for Corn?
If we must have a week with high temperatures in the 90s, the last half of June is a relatively favorable time.
Reports are provided this issue for northern and southern Illinois.
