Bartlett treated two Maple trees in my front yard for Phytophthora Canker. The treatment was a spray treatment on what surface area that could easily be reached. Later that day we had a rain shower (less than two hours after the spray was applied) and the next day we had a big rain. Was the treatment washed away with the rain?

The treatment for Phytophthora Canker is applied directly to the bark at and surrounding the site where the canker is showing signs/symptoms. The treatment has additional chemicals added to it that allow it to be absorbed by the tree directly into the bark. It will not wash off unless you soak the trunk with high pressure water from a garden hose or irrigation system right after it was applied.

The rain that day or even the day after will not affect the application.
