FPL 49 - Melampsora Foliage Rusts

Introduction

Native melampsora rusts (Melampsoraceae, Uredinales) attack a wide variety of conifer hosts that belong to a number of different genera. Some of these rusts have intercontinental distribution, whereas others are restricted to North America. There have been no detailed studies to assess the impact of these rusts, but growth loss may be expected in severe cases, and mortality may occur when seedlings are infected. The market values of Christmas trees could be reduced by these rusts.
