Non-Chemical Management
- Plant resistant red raspberry varieties such as 'Chilcotin', 'Heritage', 'Meeker', 'Nootka', and 'Willamette'.
- Plant only disease-free stock.
- Space plantings, prune, and train to provide good air circulation and reduce humidity.
- Avoid overhead irrigation.
- Do not overfertilize. Excess nitrogen promotes growth of succulent, susceptible tissues.
- Control weeds around plantings to help reduce humidity and improve air flow.
- Remove old fruiting canes and all dead or damaged canes after harvest. Also remove infected canes and destroy (burn or bury) them. Do not compost diseased materials.
