When to act

Check seedlings before transplanting and the field every week. Pull plants with mottled, fern like or puckered leaves at once, and handle them last in the day.

Before you spray

No spray cures it. Pull sick plants, wash hands and tools, and never smoke while handling seedlings.

How to prevent it

  • Buy clean, treated seed from a trusted seller, and plant a variety resistant to tomato mosaic where one is sold.
  • Wash hands with soap before handling seedlings, and do not smoke or chew tobacco while working with tomato or pepper.
  • Dip knives, pruning tools and stakes in diluted bleach or skim milk between plants and between rows.
  • Pull sick plants early, and work in healthy rows before sick ones.
  • Remove all old roots and plant debris after harvest, and rotate away from tomato, pepper and tobacco for a season.
