Abstract

Leaf anthracnose, a new disease of swallow-worts caused by Colletotrichum lineola from Russia.

Abstract

In 2010, a disease on Vincetoxicum scandens was observed in the Krasnodar area of Russia. Disease symptoms were many small, dark red-to-purple leaf spots, approximately 2-5 mm in diameter, with white centres. Leaf spots were found on the upper leaf surface. Leaf tips and margins of leaves bearing many of these spots were necrotic. The causal pathogen was identified as Colletotrichum lineola based on cultural, morphological, genetic (ITS) and pathogenicity tests. This is thought to be a new record of C. lineola on V. scandens in Russia.
