Black Knot Disease Before Tree B 6-23-2018
Tree B-This tree has only one application applied on 6-23-2018. This approach was to test compound “B” to the base of the tree. The base has 8 drilled holes with a .125” drill bit drilled about .125” deep.
This experiment is to test the ability of compound “B” to distribute through the cambium layer of the tree to all the branches and eliminate the black knot condition all over tree B. See all the pictures below of the black knot condition all over tree B. This was only applied to the healthy portion of the tree as seen in pictures at the base of the tree trunk. The tree had more than 25 locations of black knot disease.
∗ Sapwood (Xylem)—the youngest layer of wood that transports water and minerals up the tree to the branches and the leaves. ∗ Cambium—the growing layer that is only one to two cells thick. It makes new cells during the growing season that eventually become part of the phloem, part of the xylem, or more cambium. The cambium is what makes the trunk, branches, and roots grow larger in diameter. ∗ Inner Bark (Phloem)—carries nutrients and sugar from leaves down the tree to its branches, trunk, and roots.
The Tree A testing was very effective by applying to the black knot directly. The black knot disappeared very quickly. It is difficult to apply to each location and reach each are black knot typically grows. Tree B was our first test to see if you can apply directly to the trunk. Very easy to perform for anyone at any age.
This is a few of the pictures of the conditions on tree B on 6-23-2018.
