Abstract

Helminthosporium dictyoides Drechs. and H. sativum Pam. King and Bakke were the fungi most commonly isolated from plants of Poa pratensis L. infected with leaf spot in Minnesota during 1960-1962. H. dictyoides has not been implicated as a pathogen of P. pratensis (it is pathogenic on Festuca spp.) and so studies on its physiology and pathogenicity seemed necessary. Such work usually requires a large quantity of spores but H. dictyoides sporulated sparingly on the acid potato - dextrose agar used for isolating it from the plant tissue. We decided to study methods for inducing abundant sporulation as preliminary work for the more basic studies to follow.
