In 1821 in Pennsylvania a fungus commonly referred to as "black knot" was first observed. Every since then it has spread across North America, including western Canada. You may have observed this fungus on a plum, cherry or possibly a peach tree in your own backyard. It forms a black, irregular swelling and forms on the leaves, branches or even the trunk of the affected tree. Eventually the diseased tree will die because of this fungus. Once a tree produces a seed from a branch infected with the black knot fungus, the seedling will produce a tree infected with the fungus as well. This fungus is classified as a plant pathogen and is regarded as one of the worst plant pathogens due to the fact that there is no actual known cure up to this point. In the course of this project, we have attempted to find such a cure through naturopathic means. In order to do this, we have taken various oils which have strong proven anti-fungual properties and after culturing the fungus on malt agar plates, we added two drops of each oil onto five plates which had recently been touched with two drops of water homogenously mixed with the fungus. The concentration of this wass constant during the experiment. After placeing these plates in an incubator, we waited over a weekend to observe the results. In conclusion we found one of the oils to have killed the black knot fungus 100% of the time, whereas other oils were not always consistent and one oil even encouraged fungal growth.
