Abstract
Fungi are the cause of numerous plant diseases. Leading plant pathogens include various species of the genera Curvularia and Bipolaris. In this study of 21 airborne isolates, seven species with pathogenic potential for rice crops were identified (Curvularia aeria, Curvularia clavata, Curvularia pallescens, Curvularia trifolii, Bipolaris australiensis, Bipolaris hawaiiensis and Bipolaris sorghicola). For all isolates, optimum temperatures for mycelial growth and germination of conidia were determined over the 10–40 °C range. All strains were mesophilic, and optimum temperatures for germination of conidia lay within the range favourable for colony growth. In addition to their practical application in protecting the rice crop, these findings are of ecological interest in that they improve awareness of the aeromycological biodiversity of the study area.
