Abstract
Abstract A description is provided for Septoria lavandulae . Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Disease of living and withering leaves. The fungus causes small necrotic spots on the lower leaves of young plants (BOUNAURIO et al. , 1996). Further development of S. lavandulae retards growth of the whole infected plant and promotes premature defoliation (ZHUKOVA, 1977). HOSTS: Lavandula angustifolia (syn. : L. spica ), L. dentata, L. latifolia, L. officinalis, L. pyrenaica, L. stoechas, L. vera (Lamiaceae).

Europe: Bulgaria, Belgium, Czech Republic, Denmark, France, Germany, Italy, Latvia, Lithuania, Moldova, Netherlands, Portugal, Romania, Russia, Sweden, UK, Ukraine. North America: USA (Ohio, Oklahoma). TRANSMISSION: By air-borne or splash dispersed conidia from infected bushes (WORMALD, 1925); also from infected plant débris.
