Control measures are not generally recommended. Plants are subject to infection at any stage of development. Infected plants turn yellow and wilt. The lower, older foliage is affected first. Plants which are infected are either stunted or killed.
Infected plants lose their feeder roots and the vascular system of the taproot is darkened.
The fungus is seed borne and can live in the soil indefinitely. Fortunately, white rust resistant varieties also have Fusarium resistance. Cucumber mosaic virus attacks spinach causing plants to become faintly chlorotic. Chlorosis increases until the entire plant becomes yellow. Crown leaves are narrow, wrinkled and develop an inward rolling of the margins.
