  • Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

    Creator:
    Garrett, Karen A.
    Abstract:
    Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

  • Effects of host resistance on Mycosphaerella graminicola populations

    Creator:
    Cowger, Christina
    Abstract:
    Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...

  • Enhancement of biological control for postharvest diseases of pear

    Creator:
    Benbow, Jesse M.
    Abstract:
    Yeast biocontrol agents that were applied to 'Bose' and 'Anjou' pears in the field up to three weeks prior to harvest were found to survive on the fruit at high population levels on both pear varieties. Cryptococcus infirmo-miniatus, Cryptococcus laurentii, and Rhodotorula glutinis maintained populations averaging 5 x 10⁶ cfu/fruit...
