Tomatoes

Blossom-end rot is a common nutritional disorder of tomato, pepper, eggplant, pumpkin, squash, and watermelon that is caused by a shortage of calcium in enlarging fruits.

Septoria leaf spot starts on lower leaves of tomatoes as small, circular gray lesions (spots) with dark borders.

Spider mites are small arthropods typically found on the undersides of leaves during hot weather. They cause very tiny white or yellow spots on leaf surfaces and produce strands of silk webbing.

Piercing and sucking creates superficial spots (white on young fruit or yellow on mature fruit) known as "cloudy spot" on tomato and other fruits.

Small worms, usually found inside tomatoes, may be tomato pinworms.

Hornworms are large green caterpillars, often found feeding on tomato leaves.

Late blight is the plant disease that caused the Irish Potato Famine in the 1840s. This water mold disease is potentially destructive to tomatoes and potatoes that are grown in Maryland, but it rarely occurs here.

There can be numerous causes of tomato plant wilting and they should be ruled out before suspecting fusarium wilt.
