This video is a visual companion to our written fire blight symptoms, prevention and management guide. Use it to recognize the characteristic pattern of blossom, shoot and canker symptoms and to understand why timing matters.
What to look for
- Wilted, darkened blossom clusters
- Young shoots bent into a shepherd’s-crook shape
- Dark leaves that remain attached to a blighted shoot
- Sunken or discolored cankers on older wood
- Possible bacterial ooze during favorable weather
Before you prune or spray
Similar damage can result from freeze injury, drought, root stress or other diseases. Confirm the diagnosis before removing major limbs. Pruning distance and tool-sanitation practices should follow current local Extension guidance because recommendations depend on season, tree structure and disease pressure.
If considering a treatment, use only a product whose current label lists the crop and target disease. Follow label timing, rates, protective equipment and harvest restrictions. Weather-based models provide decision support but do not replace the label.
