Abstract

Brown-spot needle disease of Pines.

Abstract

A review of present knowledge of the brownspot needle disease, which most commonly affects Pinus palustris but has also been recorded on 11 other species of Pinus, is followed by an account of original studies on its developmental morphology and growth in culture. The taxonomy of the fungus is discussed and it is concluded that the correct names are Lecanosticta acicola (Thum.) Syd. for the conidial and Systremma acicola (Dearn.) Wolf and Barbour, comb. nov., for the ascigerous stage. Studies of the life history and dissemination of the fungus indicate that controlled fires are the best means of disease control in this instance. KEYWORDS:
