Abstract: The paper, based on data from literature and own studies, deals with non-bactericides based strategies for control of fire blight. Of many bacterial representatives some were selected and already used in commercial biocontrol products. They are among others: Pseudomonas fluorescens A506 (BlightBan), Pantoea agglomerans P10C (BlossomBless), Bacillus subtilis QST713 (Serenade). The principal mechanism of action of the above mentioned antagonistic bacteria is based on antibiosis and/or competition for nutrients and space. Moreover, products based on plant compounds, like AkseBio (Thymbra spicata), Biomit Plussz (various plant extracts and microelements) and bacterial products e.g. bacteriocin Serracine P (Serratia plymutica) showed satisfactory efficacy under field conditions. Also, a strategy for disease resistance induction in plants treated with Bion (BTH), Regalis (prohexadione-Ca), Palisade (trinexapac-ethyl), Messenger (harpin) and some plant extracts seems to be promising. New possibilities of apple and pear protection consists of their transformation with resistance genes such as: hrpN (harpin), dpo (EPS depolymerase) and lytic protein genes (attacin E, cecropin SB-37, T4 lysozyme)
