Rhizoctonia negative effects on soybean roots

We often talk about how cool, wet weather at planting can increase the risk of early-season diseases like Pythium. While that is true, you can’t overlook other diseases like Rhizoctonia that prefer drier conditions.

According to the October 12^th U.S. Drought Monitor, most of the Midwest is in an abnormally dry drought, which has led to more reports of Rhizoctonia root rot than normal.

Rhizoctonia root rot, caused by the fungus Rhizoctonia solani, causes damage to seedlings, but also older plants later in the season. Plants that have been attacked by Soybean Cyst Nematode (SCN) may also be more vulnerable to this disease. Rhizoctonia can kill and stunt plants resulting in yield loss and is most easily identified by rusty-brown, dry sunken lesions on stems and roots near the soil line.

Since Mother Nature is unpredictable, we don’t know what next year’s conditions or potential disease threats will be. That’s why it is crucial to make sure your soybeans are protected from the full spectrum of early-season diseases.
