| dc.description |
Needle tip dieback of 2-0 ponderosa pine seedlings at the Coeur d'Alene
Nursery was investigated. Organisms associated with dieback symptoms
were identified and infected trees were transplanted to determine
disease effects on survival. The major fungus colonizing necrotic
needles was Lophodermium nitens, a close associate of L. pinastri. The
fungus often sporulated on the necrotic distal portion of needles.
Necrotic tips were often broken during lifting and handling of seedlings.
Most infected trees produced a new flush of foliage after
transplanting and probably recovered from the disease. Control of the
disease is not warranted. |
