Recent findings suggest that garlic may be useful for treating tree diseases. Due to the anti-fungal and anti-bacterial properties of garlic, experts believe that, if concentrated, this powerful plant could be used to cure a number of deadly infections.

Operating under an experimental license, this new treatment is being tried on a number of different trees in Europe. So far it has proven successful with a number of different infections, including a fungal infection affecting the Oak trees. This fungal infection is known as Acute Oak Decline, and will almost always kill the tree. This treatment could prove extremely useful, as there are limited treatment options for Oak trees. The garlic solution is injected into the tree with a pressurized needle. The garlic is then sent throughout the tree with the sap, destroying any fungus and bacteria present.

Though not available in Canada as yet, scientists are hoping the treatment will eventually be available to treat a wide range of problems. If successful, it is hoped that the treatment will also be able to be produced in a more cost effective way.
