Bean Binoculars Incident

Areas of plant death, dieback, and non-uniform stand were observed in widespread sporadic patches across a field at the R8 (full maturity) growth stage. During harvest, yield was significantly lower in these areas. The issue was confirmed to be Soybean Stem Canker. Other symptoms include reddish-brown lesions on the main stem at the base of a lower stem, small black spots that appear on dead tissue, and dead leaves that remain attached to the stem. 

There are no management options for this season, but planting resistant varieties and rotating with non-host crops such as corn or wheat can help manage future issues.
