Host Range of Kabatiella zeae, Causal Agent of Eyespot of Maize. Francisco J. B. Reifschneider, Empresa Brasileira de Pesquisa Agropecuaria (EMBRAPA) CP. 1316, 70.000 Brasilia, D. F., Brazil; Deane C. Arny, Department of Plant Pathology, University of Wisconsin, Madison, 53706. Phytopathology 70:485-487. Accepted for publication 29 October 1979.

Sixty-three collections of the Poaceae were tested for susceptibility to Kabatiella zeae in growth chamber, greenhouse, and field environments. Although eight species became infected in the growth chamber, only four taxa, Zea diploperennis, Z. mays ssp. luxurians, Z. mays ssp. mexicana, and Z. perennis consistently showed typical symptoms in all three environments. These four taxa were considered to be new hosts of K. zeae.
