- Аннотация: The role of oospores as a source for the regular late blight renewal has been studied in a longterm experiment using tomato strains of P. infestans and two tomato cultivars. The obtained results showed that oospores, generated after the mating of strains of different mating types (A1 and A2), maintained their infection ability after their overwintering in the soil. The presence of the infectious agent in the soil causes the spreading of the late blight to the above ground parts of plants, manifesting itself on the bottom and other parts of the stem. Therefore, at least in the course of the next vegetation season, P. infestans oospores can be an important source of infection, causing the appearance of first late blight lesions on plants. http://130.226.173.223/euroblight/Workshop/2010Arras/Proceedings/Page223_230_Kuznetsova_web.pdf
