How to spot it

Leaves mottled light and dark green or yellow like a mosaic, often puckered, curled, or narrow. Plants are stunted, and fruit can be bumpy or streaked.

What it does

There's no cure, and harvests fall.

What to do now

• Pull and throw away infected plants.
• Wash your hands and tools before touching healthy plants.

Keep it away next time

• Control aphids, which spread cucumber mosaic, with row cover and reflective mulch.
• Grow resistant varieties (look for "CMV," "TMV," or "BCMV").
• Wash your hands after handling tobacco before working with tomatoes and peppers.
