Sycamore Anthracnose Treatment Options

Now that you have read all about the Sycamore anthracnose disease on the information part of this site (click here if you  missed that), you are now ready to learn what can be done about this disease.  In the past the only real option open to Arborists was to spray various fungicides on the leaves and twigs to try and control this disease.  The timing was critical and you needed to repeat these sprays more than once to have any affect at all.  The exposure to the applicator that is doing the spraying is huge and the drift from trying to spray the largest sycamores could potentially go way off target and contaminate a large area of your customers property and potentially even their neighbor’s property.  Spraying is just not an effective method of control.

Injections in the past have also had spotty results.  Drilling trees is never a good method to deliver products into your trees as the area damaged by the drill bit is then isolated and  compartmentalized by the tree.  This reduces the area available for the tree to store sugar for later use.  There are many research studies out there for review that study drilling damage.  The “guru” of arboriculture, the late Dr Alex Shigo, studied how trees react to damage in the xylem for over 30 years and his opinion on this subject was very simple, and I quote,  “Drilling trees makes no sense!”
Arbor Systems Direct inject Tree injection SystemSycamore is a thin barked species of tree, that at times is difficult to get enough product into, by injecting under the bark.   In the past, that has left arborists scratching their heads searching for other options for treatment that do not involve drilling.  That is until just a couple of years ago when Chip Doolittle, owner of ArborSystems Inc, invented the Portle needle tip for use in the Direct-Inject tree injection system pictured here.  This needle tip, designed originally for conifers and palms,  allows arborists to deal with other tree species in unique situations like the sycamores here in question.  We now can get multiple milliliters of product directly into a tree where it is needed.  Quickly, accurately, and with little damage to the tree because we ARE NOT drilling.

So now lets see how this treatment is done.  Here is a sycamore tree being prepared to accept trunk injection with multiple milliliters of product at each injection site.  The portle needles are first tapped into place with a setting tool.  The red weight slides on the shaft and assists in tapping the needle into the tree.  If you look close at the photo at the left (click on it to enlarge it) you can see the needles that are already installed.

The needles are spaced at a distance of 4-5 inches apart all the way around the tree.  To give you some perspective, this is a 30 inch diameter tree.
