Error in Figure

In the original publication [1], there was a mistake in Figure 1 as published, in which the Q-Connect (Rainbow Ecoscience, Minnetonka, MN, USA) was described as a high-pressure application device. The corrected Figure 1 appears below.

Text Correction

There was an error in the original publication [1], in which the Q-Connect (Rainbow Ecoscience, Minnetonka, MN, USA) was described as a high-pressure application device.

A correction has been made to 2. Trunk Injection Methods, 2.1. High-Pressure Injection, Paragraph 1:

The Arborjet Quik-Jet Air (Arborjet Inc., Woburn, MA, USA), is one example of a high-pressure application device. Arborjet and similar high-pressure systems, such as ENDOplant (ENDOterapia Vegetal, Girona, Spain), use 7.15 mm or larger diameter plastic plugs as injection ports which are inserted into the tree after drilling of a hole. This creates a tight seal for injection, prevents leaking, and protects the wound from pathogens and insects. Injection of the compounds occurs though specialized metal injection tips at pressures of 60–100 psi (413–689 kPa) created using compressed gas. Although the plastic plugs enable the rapid injection of large volumes of material, they can cause more damage to trees than no-plug methods, as they increase the size of the injection hole, increase the probability of injury from bark cracking, and may interfere with full wound closure [23]. Dendrology research has shown that plugging tree core wounds does not provide any benefit and can even interfere with the natural healing capabilities of the tree [33]. Another high-pressure system is the Sidewinder tree injector (The Australian Made, Loganholme, Australia).

The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
