Soybean Viruses - Symptoms
Different viruses can cause similar symptoms, and infection by more than one virus is common. Most virus-infected plants have fewer pods and are stunted to some degree. Pods may be flatter and smaller.
Leaves can show a mosaic of light and dark areas. Leaf margins may curl downward. Foliar symptoms of virus infection will be most apparent during times of rapid growth and cooler weather. Sometimes symptoms resemble injury from herbicide drift.
