Quick Fixes

Quick Assessment

Determine infection severity. If more than 50% of plant is affected, consider immediate removal.

Emergency Pruning

Immediately remove all wilted and dead branches. Disinfect tools between cuts. Dispose of infected material in trash (do not compost).

Deep Watering

Provide deep irrigation to reduce water stress. Apply 2-3 inches of water slowly to penetrate entire root zone.

Foliar Fertilizer Application

Spray balanced foliar fertilizer to provide nutrients bypassing blocked vascular system.

Copper Fungicide (optional)

Apply copper-based fungicide to root zone according to label. Limited efficacy, but may slow progression.

Intensive Monitoring

Observe plant daily. If wilting continues progressing after 7 days, consider complete removal.

Organic Treatment

Diagnosis and Isolation

Identify affected plants by cutting stems to check for brown vascular streaks. Isolate infected plants to prevent spread.

Sanitary Pruning

Remove all dead and wilted branches. Disinfect pruners between each cut with 70% alcohol. Dispose of pruned material (do not compost).

Soil Improvement

Apply 2-4 inches of mature organic compost around the plant. This increases beneficial microorganisms that compete with the pathogen.

Biofungicide Application

Water with Trichoderma spp. solution in root zone weekly for 4 weeks. Use according to manufacturer instructions.

Proper Irrigation

Provide 1 inch of water per week. Avoid both water stress and waterlogging. Use drip irrigation if possible.

Mulching

Apply 3-4 inch layer of organic mulch around plant, keeping distance from stem. This regulates soil temperature and moisture.

Monitoring

Inspect plants weekly for new symptoms. If wilting progresses, consider removing plant completely.
