Pepper Mild Mottle Virus
Tobamovirus capsici · virus · also: PMMoV
- Issue type
- disease
- Seedborne
- Yes, travels on seed
- Resistance code
- PMMoV, L1, L2, L3, L4
- Affects
- Pepper
Symptoms
Mild leaf mottling that is easy to miss, followed by the damage that matters: small, distorted, lumpy fruit with brown necrotic streaking. Extremely stable, surviving on tools, hands, and plant debris for years.
Management
The L-gene series is the textbook case of resistance genes versus pathogen races: L1 through L4 each defeat successive PMMoV pathotypes, and the pathogen has repeatedly evolved past them. Commercial seed is treated and indexed; sanitation between plantings is not optional.
