The damaging effect of the brown-spot needle blight on various southern pine seedlings has been recognized for several years, but little factual data has been available. Mr. Siggers shows that the brown-spot needle disease is one of the most important of all the variables affecting the development of natural longleaf pine reproduction. Observations of sprayed and non-sprayed seedlings, show that spraying results in increasing the average diameter of the sprayed seedlings one and one-half times that of non-sprayed seedlings. His studies show also that although a single fire reduces the brown-spot needle blight for the season following the fire, by the end of the second season the influence of the fire on the disease has disappeared.
