Abstract

In a survey of its occurrence in Queensland, Drechslera maydis was found infecting Cyperus rotundus, Digitaria ciliaris, Echinochloa colonum, Eleusine indica, and Euchlaena mexicana in addition to maize. Race T was isolated from all hosts, and was the only race identified from maize. One culture of race O was obtained from E. mexicana.
