Abstract:The southern pines, especially longleaf pine, are very susceptible to at least two important needle diseases. Of these the brown-spot disease is by far the more important. It was found that the amount of infection of the brown-spot fungus varies with the age of the plantation, but no relationship was found between incidence of infection and the physical properties of the soil. This paper is of particular interest to forest pathologists because of the new application that is made of statistical methods to the study of tree diseases.
