Wildfire disease of soybeans (Pseudomonas syringae pv. glycinea)
Symptoms consist of light-brown necrotic spots of variable size, surrounded by broad yellow halos on the leaves. In damp weather the spots enlarge forming large dead areas on the leaf. Wildfire disease is commonly associated with bacterial blight and bacterial pustule infections. The bacteria causing wildfire are seed-borne and also are carried over in crop debris.
- Disease management is the same as in the case for bacterial blight and bacterial pustule.
