Musa basjoo Deformed After Systemic Rose Treatment: Herbicide Damage

Systemic Herbicide Contamination

Bayer Systemic All-in-One for Roses contains insecticide, fungicide, and fertilizer—but is NOT labeled for edibles. Applied to bananas, it translocates into all tissues, including fruit.

Symptoms Match Herbicide Injury

• Stunted, deformed leaves that don't uncurl.
• Persistent across seasons (corm absorbed chemical).

Action Required

1. Do not eat any fruit from these plants.
2. Remove and destroy all affected plants and corms.
3. Replace soil in the planting area.
4. Start fresh with new, untreated plants.

Future Care

Bananas need no systemic chemicals. Fertilize with tropical granular fertilizer; pests are rarely problematic.
