Protective effect of brasinosteroid salicilates on spring barley plants exposed to biotic stress

In laboratory experiments, salicylates 24-epibrassinolide, 24-epicastasterone and the first synthesized 6-deoxo-24-epicastasterone salicylate act as inducers of plant immunity under biotic stress on the model phytopathosystem of barley-phytopathogenic fungus Helminthosporium teres Sacc. In small-scale field experiments, it was shown that the treatment of plants with brassinosteroid salicylates has a stimulating effect on the formation of protective physiological and biochemical reactions of plants. The most active protective effect exhibited salicylate 24-epibrassinolide.
