Harmfulness of Septoria leaf spot of winter rye under Polesye Ukraine conditions
Abstract
Results of studies of the extent of damage to winter rye varieties by the causative agent of septoria of the leaves - Septoria tritici Rob. et Desm. and Stagonospora nodorum (Berk.) E. Castell. & Germano its harmfulness is determined. It was established that the development of the pathogen depended on the genotype of the host plants and the weather conditions of the growing season of the culture. The yield losses that accounted for 5,2 % of the susceptible variety Dozor with the development of the disease up to 10 % were investigated, and for the excess lesions up to 30 % – increased to 10,4 %. On a stable winter rye variety Siverske, the development of Septoria did not exceed 10 %, and the yield loss did not exceed – 1,5 %.
