|Seedbed mulches might be thought to
have little influence on disease relationships in forest tree nurseries. In fact, mulches may serve as sources of pathogenic inoculum, or provide conditions that either favor or prevent the development of seedling diseases. This paper highlights aspects of mulch-disease interactions and summarizes a Florida study in which mulching provided useful control of Rhizoctonia seedling blight of longleaf pine (Pinus palustris). A basic understanding of the biology of soilborne pathogenic and beneficial microorganisms and the influence that cultural practices such as mulching may have on disease development is both needed and encouraged.
