My pruning got delayed this year and we have a bit early spring and a Braeburn apple tree that I think has fireblight has 2 branches that have that are dead (one in picture and another one at the top) and need to be romoved and a trunk canker(picture) I exposed last year, needs some more removal. Besides the trunk I removed a dead branch at the top and the live branch next to it. Last year I cleaned my tools with each cut with Lysol 1:2 dilution. Please confirm that this is fireblight? Should I do this cutting now or wait till next dormant season? Do you have any advise on how to do it? According to https://ask2.extension.org/kb/faq.php?id=397276 If pruning must be done during the growing season, sterilize pruning tools between each cut by spraying the cutting blade with disinfectant or by dipping the cutting surface in disinfectant for 1 or more minutes. Effective disinfectants include rubbing alcohol, a 10% bleach solution (one part household bleach to nine parts water, equivalent to 1.5 cups bleach to 1 gallon of water) and undiluted Lysol. Spray pruning wounds with clear on trees which can be infected with fireblight. Thanks for you help.
