Biological Control of SclerotiniaSclerotiorum and Botrytis Spp.
Biological control of airborne fungi by use of introduced microorganisms is still in its infancy. The disease surpressing value of naturally occurring phyllosphere microflora, which removes infection-stimulating nutrients, has been well established (Blakeman and Fokkema, 1982; Dik et al., 1991). In contrast, introduction of antagonists into the phyllosphere to control leaf infections by necrotrophic pathogens has been only moderately effective, presumably because the pathogen rapidly escapes the influence of the applied antagonists by penetrating the leaf. The period of interaction between the antagonist and the pathogen is usually too short to prevent leaf infection but could provide control through induced resistance. This typically short period of interaction requires that the antagonists should be sufficiently established in the phyllosphere before the pathogen arrives.
