Data Coverage 3 of 6 dimensions
Fusarium Crown and Root Rot can show up on landscape plants, producing visible damage that ranges from leaf spots and discoloration to branch dieback depending on severity. Early detection gives you the best management options.
Start with sanitation: remove and dispose of affected material as you find it. Thin dense growth to improve air circulation, and redirect irrigation away from foliage. If the condition persists despite cultural adjustments, your local Extension office can help identify the pathogen and recommend targeted treatments.

Management
Cultural Controls
- Best results occur when several cultural and chemical practices are integrated together.
- Use certified planting stock and set out in fertile, deep, well-drained soil (3- to 4-ft water table in winter) that has not grown small fruit (strawberry, raspberry, brambles) for several years.
- Keep affected plantings economically productive as long as possible by good cultural and fertilizing practices.
- Plant resistant cultivars if available.
- Subsoil in alleyways to promote drainage away from plants in winter.
- Install drain tiles in field to improve drainage.
