Peppers

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

Common Pepper Disease

Specific virus diseases are difficult to distinguish and produce a wide range of symptoms including stunted, slow-growing plants, twisted, crinkled, cupped, or deformed leaves, and leaf discoloration (yellow mottling and mosaic patterns, ringspots, and dark-green banding).

Borers make pinhole entrances, exuding sawdust-like frass. The foliage above bored stems may wilt or break. Borers enter peppers near the stem and feed on the seed core.

Bacterial wilt can cause sudden wilting of cucumbers, melons, and summer squash.

Gardeners sometimes are taken by surprise that changing vegetable coloration is normal or that leaves sometimes have patterns.

Periods of intense sunlight can cause vegetables to become damaged.

Poor blossom and fruit set in vegetable crops can significantly reduce the harvest in a home garden.

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.
