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.
