Susceptibility of Pecan Cultivars to Cladosporium cladosporioides Species Complex

ABSTRACT Recent studies have observed symptoms of leaf spot in pecan (Carya illinoinensis ) associated with species of the Cladosporium cladosporioides complex (C. cladosporioides, C. pseudocladosporioides , and C. subuliforme). Therefore, the present study aimed to investigate the pathogenicity of these Cladosporium spp. isolated from two pecan cultivars. Twenty-six isolates were used to inoculate leaflets of the cultivars, 'Barton' and 'Shawnee', with a spore suspension. The suspension was applied through drops on the surface of the leaflets, the material was kept in boxes, “gerbox”, in...
