Fire bliht

Asked January 17, 2020, 7:06 PM EST

Hi, I had fire blight a few years ago on my crabapples, not very severe. My tree company has been injecting the truck with a preventive but I have noticed you recommend spraying at first blossom.
I didn’t have a problem last year so should I keep doing as a preventative or wait till it appears?
It’s a pricey process
Many thanks

Here is the information we have for fire blight:

The best way to stop this disease is by preventing the disease itself. You can try planting resistant species and vigilant annual pruning. Be sure to remove all broken plant material from the area to avoid reinfection and completely sterilize all tools after every cut.
