    to the fire blight by increasing the natural plant immunity. Regoplant (Agrobiotech, Ukraina) is a new generation plant biostimulator whose action is based on synergic effect of products of biotechnological cultivation of fungi-micromycetes from root system of ginseng and Aversectine - biological product with antiparasitic action. Pear plants (Pyrus communispyrus communisSubject Category: Organism Names

    L. 'Packham's Triumph') treated with Regoplant (100μl l-1) before and after inoculation with the bacterial suspension were used in the investigation. As a control the same plants without Regoplant treatment were used. Best results were obtained in variant 3, in which the plants were treated with Regoplant, and 5 days later the artificial inoculation was done. In this variant, the lowest leaf attack index (18.46%) was recorded, followed by variant 2 (32.85%) and the control (34.66%).
