title: Antagonistic interactions of phylloplane bacteria with Drechslera dictyoides (Drechslera) Shoemaker.
abstract: Strains of Listeria denitrificans (E2), Pseudomonas fluorescens (C37 and C92), and Xanthomonas campestris (D119), isolated from the phylloplane of Lolium perenne (S24), were antagonistic to Drechslera dictyoides (Drechslera) Shoemaker. From in vitro and in vivo experiments it was deduced that their mode of activity included an initial inhibition of spore germination, a retardation in the rate of germ-tube elongation, and ultimately lysis of the hyphae. The effects were expressed on the plant in terms of reduced levels of disease symptoms and sporulation.
