The study of the parasitic fungus Sphaeropsis sapinea life cycle shows that the conidia disseminate most massively during the period of April-May, i.e. during the critical time of infection, but also during the period of June-August. Infection can occur through the buds in the spring, before their flushing, but also in the summer of the year of their development. Infection occurs most frequently through the bark of the young shoots, because of which they die while needle infections mostly lead to the so-called localised infections. Both male and female flowers can be infected, as well as the current-year and second-year cones. In some cases this fungis can behave as a latent parasite, i.e. endophyte.
