| Popis: | Persimmon anthracnose has been a great concern to Brazilian producers. This study aimed to identify and characterized the causal species from Brazilian persimmons byassessing morphological and molecular characteristics and pathogenicity tests. Five fungal isolatesobtained from diseased twigs and fruits were identified as Colletotrichum horii, based on morphologicalcharacteristics and nucleotide sequences of ITS region. Inoculation tests revealed that the fungal isolates caused necrotic spots followed by defoliation of leaves, blight of twigs and buds of potted persimmon plants. Antracnose do caqui tem sido uma grande preocupação para os produtores brasileiros. O objetivo deste estudo foi identificar e caracterizar as espécies causadoras deantracnose avaliando as características morfológicas, moleculares e testes de patogenicidade. Cinco isolados, obtidosa partir de ramos e frutas doentes, foram identificados como Colletotrichum horii com base nascaracterísticas morfológicas e sequências de nucleotídeos da região ITS. Inoculações revelaram que os isolados causarammanchas necróticas seguido de desfolha, queima de ramos e gemas em plantas de caqui cultivadas emvaso. |
