Biocontrol agents, resistance inducers and genetic engineering for protection of apple and pear against fire blight (Erwinia amylovora) (abstract only)
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)
