High pressure micro-infusion tree injection device

A method of using an injection system as a diagnostic tool to assess whether a tree is no longer viable, wherein the injection system comprises:

• a) at least two fill bottles for containing an agent to inject into the tree, the at least two fill bottles comprising an open end and a closed end;
• b) a cap attached to the open end of each of the at least two fill bottles, each cap comprising at least two ports and an on/off valve;
• c) a main line connected to each cap through a port, wherein the agent flows out of each of the at least two fill bottles and into each main line;
• d) a parallel distribution system (PDS) connected to each main line, wherein each PDS comprises multiple ports, each of the multiple ports either being closed or connected to an injection line, and further wherein each PDS is optionally expandable by combining a PDS with additional PDS units;
• e) at least 2 injection lines connected to the PDS through the PDS ports, wherein the agent flows through the injection lines;
• and
• f) an injection needle attached to each injection line, wherein the agent flows through the injection needle into the tree;
• and
• wherein the method comprises:
• g) filling each of the at least two fill bottles with the agent, wherein each of the at least two fill bottles is filled with the agent though a fill port and without removing the cap from each bottle;
• h) pressurizing each of the at least two fill bottles to be between 30 psi-120 psi;
• i) turning each of the at least two bottles filled with the agent from step (g) upside down to force an air bubble into each of the at least two bottles;
• j) placing each main line from each fill bottle into each injection site;
• k) turning the on/off valve in each of the caps to an on position, wherein turning the on/off valve to the on position opens the valve to allow the agent to flow out of the bottle through the main line and into the injection site of the tree;
• l) evaluating whether the air bubble moves within the bottle;
• and
• m) determining that the tree is no longer viable if there is no movement of the bubble.
