Protection plants of cucumber (Cucumis sativus) based on the biological characteristics of the development of bacteriosis

Relevance. Large differences in the climatic conditions by the region Altai by years determine the prevalence and harmfulness of diseases, therefore, monitoring by the dynamics of disease development and assessing their harmfulness are relevant and necessary measures. An important role in modern plant protection technologies against diseases play biofungicides. The main advantages of biofungicides as compared with chemical plant protection products are safety for humans and the environment, short waiting times and the possibility of use throughout the growing season, the absence by risks of the emergence of resistant pathogens, the creation of conditions for the natural self-regulation of agrocenoses.
