The tomato potyviruses are transmitted plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and localized.
How is the mosaic virus spread?
Mosaic viruses can be spread by weeds, infected seeds, an infected plant, or certain insects. Mosaic virus overwinters on perennial weeds and is spread by insects that feed on them. Aphids, leafhoppers, whiteflies, and cucumber beetles are common garden pests that can transmit this disease.
How can you limit the spread of tomato mosaic virus?
Non-chemical control
- It’s recommended to remove plants with symptoms promptly, as they will be acting as a source of infection for other healthy tomato plants nearby.
- After handling infected plants, wash hands and tools in hot soapy water.
- Avoid growing other susceptible plants in close proximity.
