Stamen Blight

This raspberry disease causes stamen and flower damage but detailed information about symptoms, conditions, and management is unavailable. The economic significance and prevalence remain unclear. Monitoring is recommended until better diagnostic and management information becomes available.

Remove blighted tissue promptly, cutting well below visible symptoms. Improve air circulation by thinning dense growth. Avoid overhead watering, especially during bloom and new growth periods when tissues are most susceptible. For recurring problems, preventive fungicide applications timed to protect new growth can reduce infection, but cultural controls should be your first approach.
