Isolation, morphological identification and pathogenicity of Cylindrocladium scoparium and C. clavatum isolates obtained from plants rhizosphere cultivated in Pernambuco State

Isolamento, identificação morfológica e patogenicidade de isolados de Cylindrocladium scoparium e C. clavatum da rizosfera de plantas cultivadas no Estado de Pernambuco

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.
