Besides IDC, there are limited reports of bacterial blight. Northwestern Minnesota Soybeans are beginning to pull out of iron deficiency chlorosis (IDC) and are close to closing rows in this part of the state. The bottom line for growers is to scout for soybean aphid to make sure applications are cost effective while reducing the risk of developing insecticide resistance. Miller’s team has been monitoring soybean aphid for several weeks and have not found any significant infestations.

More concerning in this part of the state is the level of field spraying activity for soybean aphid. Observations from around the state Southeastern Minnesota To date, there have not been any incidents of tar spot or other corn leaf diseases in either the sentinel tar spot hybrid trials or general scouting reports.
