Arbor-Jet Injection Question

[treesandsurf]

I've got the ArborJet system (QuickJet) and we've been using it to treat several pest issues on common trees here in Hawaii. However, I'm noticing a challenge with uptake of the formula especially in Banyan species (I believe because of the latex and sap flow that develops once you drill into the tree).

Has anyone encountered this problem with certain species, and developed a good solution for the issue? I'm thinking maybe the TreeIV may deliver the solution under more pressure but I already invested in the QuikJet so I'm hoping to find a solution using this device. Thanks for any help,

Resinous trees (usually conifers) in our area are limited to less than 2 minutes between drilling and infusion/injection. This can be an issue, depending on how you proceed.

Since the resin can dry out and impede uptake, you want to drill, plug, and needle each hole one by one, rather than drilling them all, plugging them all, and needling them all. The Tree I.V. makes that relatively easy. You can prime each site, followed by opening the bottle valve which delivers to all connected sites (usually four needles), simultaneously.

If all you have is the Quickjet, then just do the entire procedure for each site (including infusion/injection), one at a time.

The larger the DBH, the more this is a concern. You may want to invest in three I.V. systems (1 pump, 3 bottles, 3 valves, and 12 needles). This can make large trees a snap.

Also, there is a time of day usually mid to late afternoon on a hot dry day, that trees really slow down transpiration. The best time to infuse/inject is in the morning, with decent soil moisture.

Be aware that too much pressure to force the formulation into certain trees can result in, quite literally, blowing the bark off the xylem.

Swingdude, from Barbados, showed me the result of resin on his lanyards and climbing lines. Not pretty...though I don't know how that resin would equate to resin and sap up here in New England.

Best of luck!

This is the normal approach that I take, despite some difficulty with certain species we have seen some improvements visually in the crown after several months of treatment(s). The latex/sap in a Banyan or similar tropical species is unlike anything I've seen in temperate regions.

I've heard of hydraulically powered injection devices but this seems like it may run the risk of damaging trees internally (destroying structural cells, xylem and phloem tissues) but I'm not sure if that's true or not.
