Resumo: |
Torch ginger is one of the most commercially exploited species in the state of Pernambuco. It is a highly appreciated species due to the characteristics of its inflorescences. The occurrence of diseases such as anthracnose leads to loss of aesthetic and commercial value. Anthracnose caused by Colletotrichum species is one of the most important diseases in torch ginger. The present study aimed to characterize Colletotrichum spp. associated with torch ginger anthracnose in producing areas in the states of Ceará and Pernambuco. A total of 48 Colletotrichum isolates were identified using DNA sequence data (APN2, APN2/MAT-IGS, CAL, GAPDH, GAP2-IGS, GS and TUB2) and the following species were found: C. crysophilum, C. fructicola, C. siamense, C. theobromicola, C. tropicale, and three novel species, described as C. atlanticis, C. floscerae and C. zingibericola. All Colletotricum species in this study represent the first report of torch ginger anthracnose in Brazil. C. atlanticis was the most prevalent species. All species were pathogenic in torch ginger. There were significant differences in virulence between species. The species of C. atlanticis, C. floscerae and C. zingibericola were the most virulent. |
