Abstract

Dwarfmistletoe infection reduces growth rates and increases mortality rates. These losses are roughly proportional to intensity of infection and are greater than would be expected on the basis of dwarfmistletoe effects on crown condition as rated by Keen's system. In most circumstances, good management requires rigorous discrimination against infected trees.
