The patented QUIK-jet AIR from ArborJet offers precise dose measuring and air-powered injection in a lightweight aluminum body.
Belter, BCMA, owner of ArborCare & Consulting , advisor to Mauget , and an industry educator. “Studies show high pressure causes more damage to trees at the injection site,” he said. “Also, chemical solutions with an insufficient water-to-chemical ratio can cause further damage and phytotoxicity, especially when there’s high heat and less soil moisture.”
lined chestnut borer and bronze birch borer, as well as seasonal control of Japanese beetle, bagworm, oakworm, and others. Brewer said the higher con- centration means quicker delivery. “You can set the equipment to howev- er many milliliters and just give it one port,” he said. “Then you’re giving it an even distribution around the base.” Of course, micro-injections aren’t the silver bullet for every plant health care scenario. If the tree is too large or too compromised, or if uptake conditions are poor (due to excessive heat, cold or sat- uration), the outcome may not be ideal. “If it’s 95 degrees out, am I going to get good results from my injection? Probably not,” said Bill Stringfellow, managing director for Quest Products Corporation . “You’re going to get better results when it’s cooler and you have some wind blowing and when the tree is actively transpiring. You’ll get better uptake, basically.” The nature of micro-injections might also make them inappropriate for some trees in certain situations, said Kevin
MACRO-INJECTIONS: HIGH-VOLUME SOLUTIONS FOR HIGH-STAKES ISSUES
Some diseases, however, require a big- ger response. Macro-injections require a larger hole (typically a 3/8-inch di- ameter) and a much higher amount of liquid going into the tree. Instead of a small amount of a very concentrated
A trunk injection delivers systemic treatment directly into a tree’s vascular system. Injections are recom‑ mended between mid-June and mid-July for optimal uptake.
