Figure 4. Foliar symptoms of red crown rot in the soybean canopy. A – Foliar symptoms often begin with subtle yellowing flecking (chlorosis) of the leaves; B – As the disease progresses, chlorotic and necrotic lesions develop between the leaf veins (interveinal chlorosis and necrosis), followed by browning and death of the affected tissue. C and D – On individual plants, leaves may exhibit a combination of yellow and brown interveinal lesions, along with leaf curling and wilting during the hottest part of the day as root function declines. These symptoms can closely resemble those of sudden death syndrome (SDS) and brown stem rot, making examination of the lower stem and roots essential for an accurate diagnosis.
