Corky Ringspot 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
- Do not plant in soil containing Xiphinema spp.
- Use certified planting stock.
- Fallow a site for 18 months prior to replanting to eliminate nematodes.
- Use a cover crop for a year that is a non-host for ToRSV such as sudan grass that allows the nematodes to multiply.
- This flushes the virus from the nematode.
- Rogue out and destroy suspicious or diseased plants from fields once the presence of tomato ringspot virus has been confirmed.
