Most fungicide applications help prevent spores from taking root on healthy leaf tissue. They need to be applied as a preventive. Exceptions to this for one would be powdery mildew. These liquid applications are lucrative money makers for the big name tree companies, who can afford the liability. As a result I see too many trees sprayed unnecessary.Nor would it work! Unless I am mistaken, that's like putting your boots on after you ran barefoot through a pile of broken glass.
Diluted goat milk works great on mildew, but especially powdery-white mildew.Most fungicide applications help prevent spores from taking root on healthy leaf tissue.

For our next ID challenge, name the tree, the issue and recommended treatment if necessary. View attachment 1117711View attachment 1117710View attachment 1117712
Makes sense on the treatment. We can get them on our blueberries here. So treatment is top of mind when I see those tracks.Very good Spurious, it is locust leafminer on black locust. Systemic treatments in May or June is best. However most don't consider black locust as a tree worth treating. Sometimes this insect is found on honey locust. Customers will have these trees treated to help prevent early leaf drop. This pest is not considered a real threat to the health of locust trees. As you drive along the highways you'll find locust trees brown and defoliated from this insect.
Good pics, things that that you'll need to post to help with the ID.
A picture so the tree can be identified.
There are many different types of heart rot fungi, a picture of the fruiting bodies is also needed.
Excessive galleries, and in a telltale pattern for a common Doug Fir pest.Looks like galleries on the cambium
Yeah, that's the easy part. The galleries are pretty common. Death isn't. Was it the beetles or the fungus, or some qualified combination of the two? Could this have been caught early enough to save the tree? What's the implication for adjacent trees? Diagnostic techniques? Hazard?Douglas fir beetles, but that seems too easy an answer?
