Potatoes

Colorado potato beetles will create holes in eggplant or potato leaves.

Potato tuberworms feed between leaf surfaces and bore into stems of potato plants.

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.

Common scab is a bacterial disease that produces circular, corky, raised lesions or bumps on the tuber or root surface of potatoes.

Sometimes on large-fruited tomato cultivars, the top of the tomato remains green and doesn't entirely ripen.
