Pear blight treatment11/11/2023 ![]() agglomerans strain Eh-24 labelled with StrR+ was applied at 30% and 100% bloom to monitor the colonization and population dynamics of P. amylovora in each pear orchard than the bioformulation treatment. Copper oxychloride+maneb was less effective in reducing the incidence of blossom infection by E. agglomerans strain Eh-24 reduced the percentage of blighted blossoms on pear orchards by 63% to 76%, approximately. In the orchard trials conducted in 19, talc-based formulation of P. agglomerans strain Eh-24 was sprayed on pear trees which were naturally infected with E. Pear orchard trials were replicated for two years (19) in each place. Talc-based formulation of Pantoea agglomerans strain Eh-24 was applied at 30% and 100% bloom on two pear orchards which were selected from different locations in the Aegean Region in Turkey. Unfortunately, there is no 100% effective prevention measure for Fire Blight, and the best way to avoid damage is to carefully monitor your trees for early signs and prune out as soon as possible.Biological control by using epiphytic bacteria against Erwinia amylovora has been considered as an alternative method for controlling the disease. A copper sulfate spray in early spring can also reduce the rate of infection. Prevention of Fire Blight starts with selecting disease resistant varieties of your trees (see below). This can be done by dunking or wiping your pruner or saw blade or by using a spray bottle to coat the blade in between each cut. ![]() Use rubbing alcohol (70% concentration preferred) or a 10% bleach 90% water solution to sterilize. It is very important to sterilize your tools between each pruning cut (a good general practice anytime you’re pruning during the active growing season) to avoid spreading the disease. Pruning cuts should be made into healthy wood, at least 6 to 12 inches below where you see any sign of infection.Ĭheck out POP’s YouTube Channel for other videos on ecological orchard care! Prune off diseased wood as soon as you notice it to prevent it from spreading. During the summer, the best way to prevent additional fire blight spread is to control sucking insects like aphids and leafhoppers.Īn otherwise healthy tree showing signs of Fire Blight can be cared for and managed through pruning of damaged areas.When growth stops, the spread of fire blight should also stop. It is not recommended to cut out infected shoots after terminal growth has stopped.If burning is impossible, you can dry out branches thoroughly and mulch them later with a chipper. For disposal of infected branches, prunings should ideally be burned offsite from the orchard.When pruning larger limbs, consider using the ugly stub method: make a cut about 6-12 inches below the fireblight and if the location of the cut is awkward, then remove the remainder of the branch later during winter pruning. ![]() ![]()
