English Name

Mosaic Viruses

Description

There are many types of this common virus. Each one causes a similar type of damage but targets different plants. Some susceptible vegetables are cucumbers, lettuce, melons, peppers, potatoes, raspberries, squash, tomatoes and watermelons. Many of these viruses are spread by cucumber beetles and sucking insects such as aphids and leafhoppers.

Symptoms

These viruses attack plants causing symptoms such as white, light green and yellow mottling and streaking on the leaves, curling and distortion of leaves and shoots and stunted growth.

Control

Mosaic viruses are incurable, but the spread of the virus can be controlled. Place row covers over susceptible plants until they bloom. Destroy infected plants immediately and control weeds.



Did you know?

The world's tallest-growing tree is the coast redwood (Sequoia sempervirens), which grows along the Pacific Coast of the United States, mainly in California. Interestingly enough, it's not the world's oldest-growing tree; that award goes to a bristlecone pine (Pinus aristata).
