Diagnosing Green Bean Pod Abortion and Mosaic Virus

Symptom Analysis

Lush foliage but pods shriveling at 1-2 inches suggests:

1. Bean Common Mosaic Virus (BCMV): Causes pod distortion, mottling, stunting. Spread by aphids and infected seed. Your "green and lush" plants may mask early infection.
2. Nutrient imbalance: Excess nitrogen (from manure?) promotes foliage over pods. Deficient phosphorus/potassium limits pod fill.
3. Heat stress: >90°F causes blossom drop and pod abortion.
4. Inconsistent moisture: Drought stress during pod set.

Immediate Actions

• Remove and destroy (don't compost) symptomatic plants to reduce virus spread.
• Apply balanced organic fertilizer (e.g., 4-6-4) if soil test shows low P/K.
• Mulch heavily; ensure consistent moisture (drip irrigation).
• Control aphids (virus vectors) with insecticidal soap or neem (evening only).

Prevention for Future Crops

• Buy certified virus-free seed from reputable suppliers.
• Choose resistant varieties: 'Provider', 'Contender', 'Jade' (BCMV resistant).
• Rotate crops: 3-year break from legumes.
• Soil test annually—maintain pH 6.0-6.8, balanced fertility.

Virus management is about exclusion and vector control. Once infected, plants cannot be cured.
