Pathogenicity of 83 Curvularia isolates including 76 isolates from corn and 7 isolates from other hosts were tested in seedling and adult stage of corns. Among these species based on morphology, C. lunata, C. pallescens, C. lunate var. aeria, C. clavata and C. ovoidea could cause the typical Curvularia leaf spot symptom that lesions are grayish spots up to 1mm in diameter appear in the centers and straw-colored or chlorotic halos may surround the lesions.
