In organic fruit growing effective control strategies are needed to prevent blossom infections by the fire blight pathogen Erwinia amylovora. Many potential control agents are under discussion and have been tested in vitro and in vivo. 19 out of 27 tested preparations showed a high efficacy against E. amylovora in vitro. Nevertheless, on detached apple blossoms only 7 of them led to a symptom reduction by more than 50%. In six field trials conducted according to the EPPO guideline PP1/166(3…

Development of a strategy for fire blight control in organic fruit growing.
TLDR
Results and data on field performance from the literature indicate that Blos-som-Protect is the most effective preparation to prevent blossom infections by fire blight.
Development of strategies for fire blight control in organic fruit growing
Fire blight (Erwinia amylovora) is the most serious bacterial disease in pome fruit. Effective control strategies are needed to prevent blossom infections by E. amylovora. In Germany, many potential
Fire blight control strategies in organic fruit growing
TLDR
A strategy to alternate BlossomProtect applications with sprays of a mixture of Netzschwefel Stulln and MycoSin was tested and the total number of applications could be reduced to four, with only a slight decline in fire blight control.
FIELD RESULTS FOR THE EFFICACY OF FIRE BLIGHT CONTROL AGENTS IN THE LAST FIFTEEN YEARS IN GERMANY
Fire blight caused by Erwinia amylovora is the most serious bacterial disease in apple and pear. During the last four decades, it has spread throughout Europe. Under favorable weather conditions E.
Efficacy of fire blight management in pome fruit in northern Israel: copper agents and their effect on yield parameters
TLDR
monitor the effects of treatments with copper-based agents during blossoming in reducing fire blight damage, while recording their effects on pollen-tube germination and fruit-yield parameters and copper application against fire blight in pears and apples during their blooming in Israel is both effective and harmless to yields.
Real-time PCR detection of Erwinia amylovora on blossoms correlates with subsequent fire blight incidence
TLDR
An improved protocol to be used directly on whole bacteria in the field is described, allowing for early detection and quantification of the pathogen prior to the occurrence of first symptoms of fire blight.
Difficidin and bacilysin produced by plant-associated Bacillus amyloliquefaciens are efficient in controlling fire blight disease
TLDR
It is shown here that the antibacterial polyketides difficidin and to a minor extent bacillaene act efficiently against E. amylovora.
Biocontrol yeasts: mechanisms and applications
TLDR
Yeasts represent a largely unexplored field of research and plentiful opportunities for the development of commercial, yeast-based applications for plant protection exist, but the scarcity of fundamental studies on yeast biocontrol mechanisms and of registered yeast- based biocOntrol products is highlighted.
