This is a situation in which Quaking Aspen had become infected with a black leaf fungus, which caused the leaves to become black. The property owner had his trees sprayed with a fungicide each year, but the disease always came back. The treatment proved to be ineffectual over time. This year (1998) the property owner decided to try BioVam Mycorrhiza with his Quaking Aspen.
OBSERVATIONS: After treating the roots of these trees with BioVam Mycorrhiza via probe holes into the root zone, the progress of the fungus stopped within the first week. It didn't remove the fungi from those leaves already infected. The fungi stopped spreading to non-infected leaves. New growth that came in after the BioVam was applied were uninfected by the black leaf fungus and remained green after the original infected leaves had fallen off the tree in the fall. On individual leaves, the fungus progression was stopped after applying BioVam mycorrhiza. The green leaves that grew in after the BioVam treatment remained free from Black Leaf Fungi and turned a golden color in the fall. The second year, the black leaf fungi stayed off the leaves. The third year, the black leaf fungi started to return on a small number of leaves. This suggests that BioVam should be applied every two years to Quaking Aspen trees to prevent the fungus from returning.
These first three pictures illustrate how the fungus had been stopped by the effects of BioVam Mycorrhiza applied to the roots of these plants. The health of the plant was raised even in the stress of fall and the fungus was halted.
All the leaves had dropped from this tree except for one branch that was green with green leaves on it. This is a good illustration how plants inoculated with BioVam Mycorrhiza resist environmental stresses... like the cold weather of fall. The tree did go dormant, but it took a little longer
I think its wonderful hearing about all of the positive reports from your product.
All I can say is that I applied the product with your fertilizer when I planted 2 quaking Aspen trees. I am nearly certain being in Tennessee and with the drought we are having the leaves would have burned up and fallen off, but they appear to be holding their own with the addition of supplemental water.
The conditions we are having down here have been brutally hot and dry. I guess its too soon to say (about 6-7 weeks) but they are NOT losing their leaves and new stems are growing!!!
In the same area I applied Mycorrhiza to an established Yos Weeping Cherry tree that the previous owner had planted last year. It looked in sad shape when we bought the house back in the first part of July...but now it's greener and growing pretty good...no fungus or insect problems noticed.
I also applied your product to two Bigtooth Aspen trees I had in pots. When I planted them they went thru a period of pretty bad transplant shock but are starting to look healthier. These were trees planted in direct sunlight with temps over the weeks hovering from 95 to 100 degrees.
I plan to order some Big Sage Brush (Artemesia). Could you confirm that your product would work on them. I'll keep you posted how my future plantings go. Just thought you would like to know.
P.S.: I was pretty conservative with the amounts of Mycorrhiza I used. Could you tell me if another application might bring better results? (You know a little does a little good so a lot would do even better?) Take care and I'll keep you posted. --M.D. Cleveland, TN.
Benefits to established, mature plants and trees.
The above trees are six years old. Some of the experts would scoff at applying Mycorrhiza to trees of that age. They would typically say, "The natural Mycorrhiza present would be dominant and adding more Mycorrhiza would have little effect." If that were true, then we would not be witnessing the responsiveness of these Quaking Aspen to the BioVam Mycorrhiza inoculant that was added to their root systems.
We have applied Mycorrhiza to existing Rose plants and have noticed the same results as what were achieved with the Quaking Aspen above (see our Rose pictures on this site.) The fungus on the leaves of those Rose plants did not spread to other leaves after the Mycorrhiza was applied.
There is a tendency of growers to say, "But my (fill in the name) trees are not Quaking Aspen or Roses!" Our response based upon our observations is this: With Mycorrhiza, the same principles apply to all of the plants that benefit from Mycorrhiza - if you raise the vitality of a plant, it may become resistant to diseases such as leaf fungi.
Traditional agriculture says, "Spray the tree with a fungicide." People have heard only that for years. With Mycorrhiza we say, "Raise the level of the plant's vitality and the tree will resist the fungi."
This picture, taken 9/6/1999, shows a Quaking Aspen with nice golden leaves. We treated the turf grass with BioVam Mycorrhiza and the Mycorrhiza vectored into the roots of this tree.
The customer remarked that they didn't realize Quaking Aspen had such beautiful fall colors. They thought the leaves turned black and then fell to the ground. The vitality of this tree was significantly increased and it was able to resist the black leaf fungi intrusion so that the golden leaves were displayed in the fall of 1999.
