Oomycetes are a particularly dangerous group of pathogens that significantly reduce both the productivity and the quality of production of agricultural crops. Protective measures using available fungicides are often ineffective against them. One of the simplest and, at the same time, innovative approaches to plant protection from oomycete infection can be considered biological methods, which, if used in a timely manner, can be even more effective than chemical means of protection. Biological control involves the use of beneficial microorganisms that can stop the development of diseases by producing biologically active substances with antibiotic activity, such as antibiotics, biosurfactants, and toxins. In this review, we describe a strategy for sustainable prevention and control of oomycete pathogens using plant-associated microorganisms, including bacteria of the genera Bacillus, Paenibacillus, Streptomyces, Pseudomonas, and Lactobacillus. The mechanisms that determine the protective effects of bioprotective strains in the endo-, phyllo-, and rhizosphere of plants are also considered, which can be used in the development of strategies for constructing phytomicrobiomes.
