Isolation, morphological identification and pathogenicity of Cylindrocladium scoparium and C. clavatum isolates obtained from plants rhizosphere cultivated in Pernambuco StateDOI: 10.1590/S1517-83822004000300004 Keywords: ricinus leaf bait, morphological markers, eucalyptus pathogenicity. Abstract: twelve isolates of cylindrocladium scoparium and 4 isolates of c. clavatum were obtained from the rhizosphere of various species of plants by baiting with ricinus communis leaves. the isolates of c. scoparium developed conidia of 32-(45)-60 x 3 -(4)-5 μm, and pyriform to ellipsoidal vesicles. c. clavatum showed conidia of 36-(44)-49 x 2-(4)-6 μm and clavate vesicles. all isolates induced necrosis on leaves and hypocotyls of eucalypt seedlings, with varying expression of symptoms.
