Objectives: Apply BioVam Mycorrhiza into holes poked into the ground in the drip line of a mature Maple tree. Observe growth differences between treated and untreated trees. Observe the effect on Aphid infestations. Observe differences in leaves, seeds, stem cross sections, and drying times when detached from the plant.
Observation summary: The leaves, seeds, and stem growth sizes are larger in the treated plant. There are more xylem vessels in the treated plant which hold more sap from the roots and make the plant much more resistant to drought conditions. The treated plant had a five year history of Aphid infestation and was not infested by Aphids as of 6/5/99. BioVam increased the health of the treated plant sufficiently enough so that Aphids would leave the plant alone, while the untreated plant, 50 feet away, was infested with Aphids and had to be treated with a systemic to control the Aphids.

Untreated Maple Tree
Treated Maple Tree
The untreated tree (above) had to be treated for Aphids. The treated tree had no Aphid problems as of 6/5/99.
These leaves (above) are the largest sized leaves from the treated tree and the untreated tree. The leaf on the left is 10" wide and it's stem is twice as long as the stem on the untreated leaf.
The seeds on the left in the above picture are from the treated Maple tree.
These seeds are typical of those produced. Untreated tree (above) and the treated tree (below).
Cuttings from the untreated tree, after two days, are drying out.
Cuttings from the treated tree, after two days, are not drying out.
Cross section taken from the untreated tree stem shows sparse xylem vessels in the cambium layer just under the bark layers.
Cross section taken from the treated tree stem shows higher numbers of xylem vessels in the cambium layer just under the bark layers. More xylem vessels means more water is in the plant and explains why after two days, the above leaves are not drying out.
The picture above shows two maple leaves. The leaf on the right is from our untreated Maple tree and shows the drippings from Aphids that have infested the tree. The leaf on the left is from our BioVam treated Maple tree and shows no sign of Aphid drippings. This is one of the benefits of using BioVam on Maple trees that we were hoping to demonstrate. This picture was taken on 6-19-99.
