Quick Fixes
Immediate Pruning
Cut all visibly infected leaves and dispose. Clean tools.
Systemic Application
Apply systemic fungicide (azoxystrobin or similar) according to package instructions. Product will be absorbed and circulate through the plant.
Reapplication
Reapply after 7-14 days as per product label.
Environmental Adjustment
Switch watering to early morning and improve ventilation.
Organic Treatment
Mechanical Removal
Remove all infected leaves and parts with clean shears. Dispose in trash (not compost). Clean tools with 70% alcohol between cuts.
Sulfur Application
Apply sulfur fungicide to all leaf surfaces, especially undersides. Do this in the morning for quick drying. Do not apply above 30°C (86°F).
Watering Adjustment
Switch to drip irrigation or water directly at soil level. If using overhead watering, do so between 5-10 AM.
Improve Circulation
Prune dense branches to increase airflow. Maintain proper spacing between plants.
Monitoring
Inspect weekly. Reapply sulfur every 7-10 days for 3 weeks. Continue for 2 weeks after last symptom.
