Disease Name
Verticillium Wilt

Scientific Name
Verticillium albo-atrum, V. dahliae
Like Fusarium wilt, a brownish discoloration forms under the outer skin of the lower stem and can be observed if split length-wise. The pith remains white and healthy. Fruits remain small, develop yellow shoulders, and may sunburn because of loss of leaves. Infected plants may wilt only slightly at first, usually during the hottest part of the day, and recover at night. Later, lower leaves may show whitening or yellowing between the veins. This discoloration may become fan-shaped and more yellow over time. In spite of the name verticillium wilt, a true wilt seldom occurs in tomato, at least not until late in the season. Rather, under good conditions of moisture and nutrition, yellow blotches on the lower leaves may be the first symptoms, then brown veins appear, and finally chocolate brown dead spots.
