Borges, Associate Professor, Instituto de Genética, Facultad de Agronomía, Universidad Central de Venezuela, Maracay. Plant Dis. 67:996-997. Accepted for publication 10 March 1983.

Drechslera sorghicola was identified as the causal organism of target leaf spot of sorghum. The fungus produces well-defined and elongated spots, which vary in size and color according to the sorghum genotype. The disease may be of economic importance in regions where high humidity and favorable temperatures occur during the growing season.
