AB  - Pecan (Carya illinoinensis Wang. K. Koch) is a deciduous tree of the Juglandaceae 
      family with important economic value worldwide. Anthracnose of the pecan leaves 
      and shuck is a devastating disease faced by pecan-growing areas in China. 
      However, the causal species occurring on pecan remain largely unidentified. we 
      collected samples of diseased pecan from the provinces of China, Leaves and 
      fruits affected by anthracnose were sampled and subjected to fungus isolation, 
      The morphological characters of all strains were observed and compared; 
      Multi-locus phylogenetic analyses [Internally transcribed spacer (ITS), Actin 
      (ACT), Calmodulin (CAL), Chitin synthase (CHS1), Glyceraldehyde 3-phosphate 
      dehydrogenase (GAPDH), and b-tubulin (TUB2)] were performed on selected 
      representative strains; examine their pathogenicity on leaves of pecan.The 
      results showed that: (1) resulting in a total of 11 Colletotrichum isolates, Two 
      Colletotrichum species were identifified to be C. fioriniae and C. fructicola; 
      (2) Pathogenicity tests revealed that both species caused black spots on pecan 
      leaves and fruit, The virulence of the different isolates varied substantially, 
      with C. fioriniae PCJD179 being the most virulent; (3) The susceptibility levels 
      of pecan tree varieties, 'Mahan' and 'Kanza', were determined, No significant 
      differences were observed in the lesion sizes produced by the various isolates in 
      'Kanza', while there were signifificant differences in 'Mahan'. This study is 
      thefifirst to determine that C. fructicola and C. fioriniaecan cause anthracnose 
      in pecan in China. It improves the understanding of the species that cause 
      anthracnose in pecan and provides useful information for the effective control of 
      this disease in China.
