The overall goal of this experiment is to treat a tree with endo therapy using tree friendly lenticular bladed tools and the Venturi effect rather than drill holes. This is achieved by separating the subcortical woody fibers with a device having a blade with lenticular cross-section to access the X matic SAP vessels. As a second step fluid from an external reservoir is taken up by the tree as the hollow blade temporarily reduces the cross-section of the SAP vessels leading to a ventry effect.
Next, after the desired fluid is taken up, the blade is removed. The xylem SEP moves up to leaves according to the transpiration rate, carrying with it the externally supplied fluid results obtained so that fluids are distributed. Further injection sites partially close soon after the removal of the blade due to the natural elasticity and rigidity of the fibers and the cambio activity completes the healing process in a few weeks, Usually professional operators familiar with traditional trunk injection methods.
We struggle because with our instrument, the number of trees to be treated per day cannot be easily planned is true. Our instrument was developed not to increase the daily productivity, but to decrease the long-term damages associated to wounds and to induce inside the tree a physical phenomenon, able to increase the natural uptake of an external liquid. Perform treatments on a day suited for endo therapy, preferably between butt break and late summer.
Select the tree which will undergo the injection treatment. Begin by measuring the circumference of the tree at breast height to determine the quantity of solution to be used and the number of insertion sites. Next in the first 150 centimeters from the ground, identify and mark the insertion sites so that they are equidistant for this 126 centimeter tree.
There are five sites. Ideally, the site locations will be slightly convex, smooth and above root flares. Prepare the injection device for use.
Choose a blade for the device with the length compatible with both the bark thickness and the tree diameter. Screw the blade to the body of the device. Put the device aside and fill a disposable pharmaceutical syringe.
With the solution required for a single insertion, each site will receive an equal share of the total liquid. Keep the syringe within easy reach. Wear gloves, protective glasses, and other protective gear demanded by the chemical agents to be used and local regulations.
Pick up the device and orient the blade edge with the fibers of the tree and direct the blade toward the center. Hold the body of the device firmly in one hand with the blade against the tree. Use the other hand to strike the sliding hammer on the body until the external lay text gasket is completely squeezed.
Once this is done, retrieve the filled syringe and insert it into the conical opening. Gently draw out the plunger. Observe the rate of infusion.
When the syringe is empty, wait eight to 10 seconds. Then remove the blade by striking the hammer in the opposite direction. Repeat with the remaining injection sites with drilled injection holes as depicted in this photo.
The surrounding tissues usually lose their vitality due to overheating. In comparison, using a lenticular blade, the camal and woody tissues are not removed, but moved aside. They partially revert to their previous shape within a few minutes and are usually perfectly healed after a few months.
These photos are of two trees 12 months after treatment with potassium phosphates Using a lenticular blade, there is only a small amount of discoloration once the trees have healed. Further treatments can be made with little concern. Here, stained pesticide is seen in palm tree PDs and palm tree leaves 24 hours after infusion.
This demonstrates the uptake by means of infusion in trees characterized by slow SEP dynamics. While attempting this procedure, it's important to take in mind that the Venturi effect takes place only when the transpiration rate of leaves is high. In cloudy or rainy days, or in the most of conifers and palms.
Transpiration can be very low. In this case, it can be convenient to gently press on the plunger or to connect the instrument to an external pressurized device.
