Pinus resinosa, P. sylvestris, P nigra, Pseudotsuga menziesii , and Picea glauca seedlings in three sites and Pinus thunbergii in two sites in New York State were inoculated with conidia of Gremmeniella abietina twice in 1986. Percent infection therefrom was determined in spring of 1987, Some members of each species of Pinus became infected at one site within the current range of the disease and in other sites 84 and 300 km south of the current range. P. glauca and P. menztesii were not infected. Results of experiments to test efficacy of postharvest treatments to eradicate G. abietina from infected seedlings suggested that immersion in hot (55°C) water and applications of dilute sodium hypochlorite would eradicate the pathogen with little or no effect on retention or color of foliage of P. resinosa and P. sylvestris.
