Pathogenicity of <i>Colletotrichum</i> species causing anthracnose of <i>Capsicum</i> in Asia

Abstract Anthracnose of chili is caused by a complex Colletotrichum species, with recent surveys reporting at least 28 different species implicated. However, there have been very few studies to identify the relative pathogenicity various or optimize bioassay assess pathogenicity. A detached Capsicum fruit determine diverse geographical range isolates scovillei showed maturity, host genotype, and inoculation method all interact affect infection rate lesion development. On annuum ‘Bangchang’ wounded prior inoculation, was consistent regardless maturity. In contrast, without wounding variability in relatively resistant chinense PBC932, dependent on both maturity stage fruit. addition, lack correlation between two lines indicated that host–isolate specialization would make prediction difficult. further study, 10 isolated from diseased fruits Asia anthracnose symptoms C . under testing conditions, large differences aggressiveness. PBC932 generally more smaller lesions produced conditions. javanense were highly aggressive other especially when inoculated nonwounded Pathotype identified within multiple siamense , most frequently pathogenic chili.
