Lodgepole Pine Seedling Chlorosis and Mortality at Bessey Nursery, Nebraska

Evaluation of chlorosis and mortality of 1-0 lodgepole pine seedlings at Bessey Nursery, Nebraska indicated possible association of soil nutrient imbalances with infection by soil-inhabiting fungi (primarily Phoma spp.). Excessive overhead irrigation used primarily for wind erosion control caused accumulation of the light soil around the base and into the foliage of some seedlings. These conditions were ideal for attack and damage by Phoma spp. Approaches to reducing losses are discussed.
