Some factors affecting the virulence of artificial inoculum of Helminthosporium sativum P. K. and B. and of Fusarium culmorum (W. G. Sm.) Sacc
Canad. J. Res 19: 42-48
In greenhouse experiments in Alberta, steam-sterilized black loam soil mixed with various amounts of maize meal was inoculated with spore suspensions of Helminthosporium sativum and Fusarium culmorum. When this inoculum was applied to grain sown in sterilized and unsterilized soil, the amount of maize meal added to the medium and the period of incubation caused significant differences in the number and dried weight of surviving wheat plants and weighted infection ratings.
