First report of Colletotrichum chrysophilum causing papaya anthracnose in Mexico
Plant Disease 106 (12), 3213-3213
Abstract: During 2020, mature papaya fruit (cv. Maradol) grown in Mexico showed typical symptoms of anthracnose. Initially, small, water-soaked lesions appeared on the fruit surface, which later enlarged to circular sunken lesions with translucent light brown margins. On advanced infections, salmon-pink masses of spores were observed on the lesions. The disease incidence of 100 papaya plants surveyed in the affected orchard was estimated at about 45%. The fungus Colletotrichum chrysophilum was isolated from the diseased plants. The identification was based on morphological characteristics and DNA sequence analysis. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
