Mechanistically compatible mixtures of bacterial antagonists improve biological control of fire blight of pear.
Mixtures of biological control agents can be superior to individual agents in suppressing plant disease, providing enhanced efficacy and reliability from field to field relative to single biocontrol strains. Nonetheless, the efficacy of combinations of Pseudomonas fluorescens A506, a commercial biological control agent for fire blight of pear, and Pantoea vagans strain C9-1 or Pantoea agglomera...
متن کاملinvestigation of changes in antioxidant enzyme and total phenol level in some pear cultivars inoculated with fire blight disease
fire blight, caused by the bacterium erwinia amylovora, is one of the most destructive diseases of plants in the rosaceae subfamily pomoideae. the objective of this study was to determine the level of resistance of 30 pear cultivars and describe the biochemical changes induced in some resistant and susceptible cultivars. the level of resistance was determined by the length of the fire blight le...
متن کاملthe study of biological control of pear fire blight caused by erwinia amylovora by some antagonistic bacteria
fire blight is an important worldwide disease of pome fruits that control of which through antibiotics is particularly critical. in this case and in absence of another chemical methods, the biocontrol methods can be considered as the best alternative for control of fire blight. in this study efficacy of 5 isolates of antagonistic bacteria belongs to pseudomonas fluorescens and pantoea agglomera...
متن کاملInheritance of fire blight resistance in Asian Pyrus species
Since several Asian pear species are considered to be potential source of fire blight resistance, we crossed ‘Doyenné du Comice’, the susceptible European cultivar, with four Asian pear species. The aim of the study was to establish the level of resistance of each genotype and the mode of transmission of fire blight resistance to each F1 full-sib progeny. The best sources of resistance were P. ...
متن کاملAnalysis of Fire Blight Shoot Infection Epidemics on Apple
Fire blight of apple (Malus × domestica Borkh.) can be found throughout the United States and many other countries and is a serious problem on trees of susceptible apple cultivars (9). Fire blight is caused by the bacterium Erwinia amylovora and occurs also on pear, quince, Rubus spp., and several other rosaceous hosts. The initial inoculum in an established orchard comes from overwintering can...
