Treating Maple Trees with BioVam

In the fall of 1998, we treated a Maple tree with BioVam Mycorrhiza.   We poked  holes 10" into the ground every 8" around the drip line of a mature Maple tree and put 1 teaspoon of BioVam in each hole and then covered the hole with soil.  There was another Maple tree 50 feet away which was not treated.  Both trees have had a five year history of requiring an annual systemic pesticide application to control Aphids.  By the end of Spring 1999, we have noticed a number of positive results to treating a mature Maple tree with BioVam. 

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

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.

Maple Leaves Treated and Untreated

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.

Maple Tree Seeds

The seeds on the left in the above picture are from the treated Maple tree.

Maple Tree Seeds

These seeds are typical of those produced. Untreated tree (above) and the treated tree (below).

Maple Leaves (Untreated)

Cuttings from the untreated tree, after two days, are drying out.

Maple Leaves (treated)

Cuttings from the treated tree, after two days, are not drying out.

Maple cutting (untreated)

Cross section taken from the untreated tree stem shows sparse xylem vessels in the cambium layer just under the bark layers.

Maple cross section (treated)

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.

Treated and Untreated Maple tree leaves.


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.
