A new race of Verticillium dahliae causing leaf mottle of sunflower in Europe
Plant Disease 98 (10), 1435-1435
Abstract: During 2013, sunflower plants (Helianthus annuus) grown in Spain were observed with symptoms of interveinal chlorosis and mottled leaves. On severely affected leaves, chlorotic patches enlarged, coalesced, and large areas of the leaves became necrotic and dried. Cross sections of the lower stem showed a brown discoloration of the vascular system. The fungus Verticillium dahliae was isolated from the diseased plants. The identification was based on morphological characteristics and PCR analysis. Pathogenicity of the isolates was demonstrated by inoculation.
