We concluded that the leaf Septoriosis (pathogens Septoria tritici Rob. Et. Desm, Erysiphe graminis DC) and brown leaf rust (pathogen Puccinia recondita  Rob. Et. Desm) are the main diseases of spring wheat leaves in the Eastern Forest-Steppe of Ukraine. We determined that the first visible signs of powdery mildew on the leaves of spring wheat appeared in the form of spots with a white spider web film. After 2–3 days, the film on the leaf blade was compacted and turned into cotton-like pads - conidial sporulation. The interval between the leaf infection to the appearance of the first visible disease symptoms, caused by Septoria tritici pathogen, was approximately 10-14 days. The period between the first symptoms and the beginning of sporulation is quite short. The incubation period of brown leaf rust development lasted for 7–21 days. We registered that the telia with teliospores were formed after 12–19 days of uredinia appearance on the mycelium.on measures. Ukrainian Journal of Ecology, 9(2), 232-238.
