Occurrence of anthracnose ( <b> <i>Colletotrichum acutatum</i> </b> ) on ornamental lupin in the United Kingdom

Abstract

The first recorded outbreak of anthracnose ( Colletotrichum acutatum ) on ornamental lupin in the United Kingdom occurred in 1989. Seedborne infection by Colletotrichum acutatum was investigated after seed was implicated in the origin of the outbreaks and infection was found on seed of three of 14 cultivars tested. In pathogenicity tests, typical anthracnose symptoms developed only on plants of Lupinus spp; there were slight symptoms on Pisum sativum Vicia sativa and Lathyrus odoratus , but none on Vicia faba, Phaseolus coccineus, P. vulgaris and Onobrychis viciifolia
