Infectivity and pathogenicity of Leptosphaeria coniothyrium and other stem inhabiting fungi on raspberry canes


, : Infectivity and pathogenicity of Leptosphaeria coniothyrium and other stem inhabiting fungi on raspberry canes. Acta Horticulturae: 41-47

During 3 yr growing seasons, raspberry canes were inoculated at the lower, middle and upper parts with L. coniothyrium and 13 other fungi. Uninjured canes were infected only by L. coniothyrium, Didymella applanata and Phoma exigua. At the lower and middle inoculation points all infections remained superficial and only at the upper points were L. coniothyrium and, less often, D. applanata able to invade the entire stem.

In a 3-year laboratory and field trial raspberry canes were inoculated in the lower, middle or upper parts between May and October with 14 fungi.
