Read and follow all labels associated with the product you are using. Most of the time, when a homeowner can apply a fungicide, it’s for a fruit tree or tree small enough to spray. Most options are very safe, but understanding what you’re treating will determine what type of fungicide you will want to use.
The most general used fungicide for trees has a copper-sodium active ingredient. It’s a broad spectrum fungicide and does a good job of treating most fruit tree fungus and cankers. Spray trees from top to bottom in the spring. Most products will call for a second application within a month to a few weeks of the previous application. Read and follow all instructions on the label. If some is good, that doesn’t mean that a lot is better!
If you aren’t sure which fungus is attacking your yard, our professional tree disease treatments can provide a definitive diagnosis before you start spraying. This is especially important for common local issues like Sycamore Anthracnose, which requires very specific timing to be effective.
