Zusammenfassung:The article describes the benefits of using plant resistance inducers on cereal crops and the basic principles of their impact on pests development (Pyrenophora tritici-repentis, Puccinia triticina, Puccinia striiformis, Puccinia graminis, Puccinia hordei). The assessment results of the biological and economic effectiveness of L-479 and DL-59 preparations are presented in comparison with the chemical Kolosal,CE and biological Albit, which were used as standards for reducing the development of yellow leaf spot and rust diseases. L-479 product was found to be the most effective on wheat against brown, yellow and stem rust, and yellow leaf spot. Its biological efficacy ranged from 48.3 % to 57.0 % depending on the pathogen, and the increase in grain yield ranged from 3.7 % to 22.1 %. DL-59 product showed the best biological efficacy against dwarf leaf rust of barley – 89.8 %, the increase in grain yield was 3.5 %.
