This is the time of year for bacterial infections! Usually, this is the result of saturated soils that remain that way for quite some time.
You can attempt to use a fungicide, but it won't completely cure the issue, usually. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
Other than that, keeping all heavily infected growth cut, and keeping debris away from the area on the ground will help to kill off the bacteria.
A dry out will be helpful, if the weather cooperates.
