Non-conventional possibilities of protection of apple and pear against fire blight (Erwinia amylovora)

摘要

Standard program of plant protection against fire blight consists of use of management practices and chemical control method. Recently a new, non-conventional possibilities based on application of biocontrol agents (two biopreparations have been already introduced into practice: Bliteban A506 ( Pseudomonas fluorescens ) and BlossomBless ( Pantoea agglomerans ), plant extracts active against Erwinia amylovora (AkseBio containing extracts from Thymbra spicata and Biomit Plussz with extracts from various plant species and microelements) and resistance inducers (Regalis, Bion and plant extracts) are of great interest. Also plant transformation with resistance genes such as: hrpN (harpin), dpo (EPS depolymerase) and lytic protein genes (attacin E, cecropin SB-37, T4 lysozyme) is a promising perspective.
