Septoria helianthi Ell. & Kell. nuovo parassita del girasole in Italia

Abstract

Viene segnalata per la prima volta in Italia, la presenza di Septoria helianthi Ell. & Kell. su girasole (Helianthus annuus L.), cultivar Gloriasol. La malattia diffusa su un gran numero di piante, si presentava sottoforma di tacche necrotiche irregolari o poligonali circondate da un alone clorotico e procedeva gradualmente dalle foglie basali verso quelle dei palchi superiori. Le particolari condizioni climatiche (abbondanti piogge e basse temperature primaverili) e l'uso di semente infetta vengono considerate le cause principali per l'introduzione e la diffusione del parassita
