Cucumber mosaic virus causes mottled foliage and distorted growth on affected plants. You see yellowing and leaf mosaic patterns with reduced vigor. The virus reduces crop quality significantly. Remove infected plants and control aphid vectors that spread disease.
There is no cure for viral diseases. Remove and destroy infected plants to prevent spread to healthy ones nearby. Many viruses spread through insect vectors like aphids and leafhoppers, so managing those populations helps slow transmission. When replacing removed plants, choose virus-resistant varieties if available and purchase certified virus-free stock from reputable nurseries.

Management
Cultural Controls
- Plant resistant or tolerant varieties; 'Niagara' is resistant; 'Burpee', 'Dasher II', 'Gemini', 'Marketmore', 'Multipik', 'Pioneer', and 'Surecrop' are tolerant
- Control aphid vectors with insecticides when populations are high
- Control weed hosts (wild cucumber, milkweed, nightshade) in and around growing areas
- Remove and destroy infected plants immediately
- Avoid mechanical transmission through contaminated tools and hands
