Soil-borne disease problems such as leak and silver scurf also can be serious. Bacterial Ring Rot symptom expression is erratic and difficult to see under most circumstances. Reaction to PVY infection is mild to latent. Infected plants are difficult to detect early in the growing season, but usually express mild symptoms that become somewhat more detectable as the plants age. Infected plants tend to die by mid-season with potentially significant yield losses when PVY incidence is high.
Plants appear windburned with dehydrated leaf margins in the upper canopy.
A light brown, jelly-type rotted mass is all that is left of the seedpiece and brown streaks may be visible in the lower stem. Normally the plant recovers within a couple of weeks. This problem may be present when early season wet conditions are linked with warm weather.
