Abstract

Bipolaris maydis was consistently isolated from infected Paspalum atratum cv. Pojuca plants showing leaf spot symptoms in the Cerrado of Brazil, in 2002. Pathogenicity tests under greenhouse conditions and subsequent reisolations of B. maydis from artificially inoculated Pojuca seedlings confirmed the hypothesis that this fungus was the causal agent of the disease. Symptoms of leaf spot appeared four days after inoculation in 100% of the inoculated Pojuca plants. All seven species of grasses evaluated were susceptible to B. maydis. The occurrence of leaf spot of Pojuca caused by B. maydis is reported for the first time in Brazil.
