The recent outbreak of Lophodermium needlecast in North America first appeared in 1966 in forest nurseries on red pine ( Pinus resinosa ) and Scotch pine ( P. sylvestris ). Dispersal of infected nursery stock throughout North America has created a serious needlecast problem in Scotch pine Christmas tree plantations. Two biotypes of L. pinastri are present. The pathogenic strain may be a recent introduction. The fungicides maneb and chlorothalonil are being used for control.
