Title: Brown-Spot Needle Blight of Pines

Author: Phelps, W.R.; Kais, A.G.; Nicholls, T.H.;

Date: 1978

Source: Forest Insect & Disease Leaflet 44. [Broomall, PA:] U.S. Dept. of Agriculture, Forest Service, Northern Area State & Private Forestry

Publication Series: Forest Insect and Disease Leaflet (FIDL)

Description: Brown-spot needle blight, caused by Scirrhia acicola (Dearn.) Siggers, delays growth and causes mortality of longleaf pine (Pinus palustris Mill.). Brown spot reduces total annual growth of southern pines by more than 16 million cubic feet (0.453 million cubic meters) of timber. Damage is most severe on longleaf seedlings in the grass stage; i.e., those that have not begun active height growth (fig.1). Heavily infected seedlings may remain in the grass stage for 10 or more years. Brown spot has also become a serious problem to certain varieties of Scots pine (P. sylvestris L.) and other pines grown in Christmas tree plantations in the north- and mid-central States (see photo) Thousands of dollars are lost annually by Christmas tree growers because this fungus causes needle drop, making trees unmerchantable.
