Ways You Can Determine Proper Pest Management Solutions

Ways You Can Determine Proper Pest Management Solutions

When it comes to weighing options for tree pest and disease treatments, determining the best solutions for clients' trees often requires more careful consideration than expected. Thanks to the observations and experience of industry experts such as Davey's Jim Zwack, you can eliminate a bit of the guesswork.

Zwack, director of technical services for the Davey Institute and regular TCI EXPO attendee, recognizes the importance of understanding tree injection versus soil applications and the benefits, disadvantages and purposes of each.

"Injection is a closed application system that continues to earn more focus ," Zwack explains. "We are on the front line of that--where it's going in the future and how it's continuing to grow in the industry."

Tree injections involve direct insecticide or pesticide application into the trunk of an affected tree, while soil applications involve injecting substances into the ground at the base of the tree trunk. But which technique is better for your trees?

Pest Management: Tree Injection vs. Soil Application

The difference between tree injection and soil application lies among each method's pros and cons listed below:

Tree Injection | Advantage

  • A large volume of treatment reaches the tree in a short period of time.

Tree Injection | Disadvantage

  • Openings or "wounds" develop along the surface of the tree trunk. (Wounds, however, heal quicker following a proper tree injection.)

Soil Application | Advantage

  • Soil applications are non-invasive.

Soil Application | Disadvantage

  • Treatments applied at the base of the tree may negatively affect the quality of surrounding soil and water.

Consult a professionally trained arborist to help you determine which pest treatment is best for your trees.

Although benefits to each method exist, a professional consultation can help you determine which technique is most beneficial to your trees.

Pest Management: Know the Options

"Clearly we need a balance between this array of challenges that confront our urban forests and the volume of solutions we can capably provide," Zwack says.

Because websites and mobile apps have helped educate homeowners and property managers about the trees they have, their associated problems and potential solutions serving the modern client requires a broad selection of solutions.

According to Zwack, the opportunity to take advantage of multiple options increases the likelihood trees will receive proper care. "It's a good thing to have multiple tools available," he says. "Multiple tools allow you to match treatment needs with clients' trees."

Know your pest management options before treating your trees.

However, the potential number of cultural practices, products and application techniques that could be used to address this multitude of issues only increases the range of treatment possibilities. "Have you ever done the math to see how many combinations of tree species plus insect pests plus diseases plus abiotic stresses are out there?" Zwack asks. "Me neither."

Zwack believes industry leaders need to embrace a fair amount of this complexity if they'd like clients to perceive them as professionals; put simply, arborists should aim to show they're not causing more harm than good. "We all want to be seen as professional specialists," Zwack says. "And clients want more advanced options; it helps to see different ends of the spectrum."

Jim Zwack, director of technical services for the Davey Institute, will present to TCI EXPO attendees on Friday, Nov. 15. His presentation titled, " How to Incorporate Tree Injection into Your Business/PHC Services," covers the effectiveness of different tree injection techniques and how the technology has evolved to help damaged trees.

  • John Rickloff July 26, 2016 >We have a huge oak tree in the backyard that seems to be dying off. We suspect bugs at the base and really don't want to lose it, but fear it may already be at that point.

  • From Research to Reality

    Have you ever sat and watched a tree swaying in the wind? Sure, many of us have on a nice, cool, summer day. Now imagine studying that tree's canopy movement using 3-D motion tracking - like a video game showing how a tree, its branch structure and leaves billow in the breeze, analyzing each fraction of movement.

    And what if this type of tool can actually help you determine how stable that tree really is when it's being shaken by air currents or even how much strength is sacrificed in the process?

    What could this do for an arborist? A lot. It can help them better assess safety risks when climbing and pruning a tree. It can even help them determine the entire pruning plan to do what's necessary to restore or retain that tree's normal strength. What does this do for you - the person enjoying the tree on a daily basis? Even more. It means you get to watch that tree grow happier and healthier and stronger for a longer period of time, adding value to a property and providing all the benefits for which trees are best known.

  • Show Me the Money!

    OK, I have an experiment I'd like you to try with me.

    Go outside, walk up to one of your trees, gently grab one of the lower branches and carefully uncurl one of the leaves. Now take a close look (I'm envious of those of you in the south and west who can do this now - northerners will have to wait a bit…hang in there, spring is almost here.)

    Do you see something green? (Your answer should be yes.)

  • Trees Got Your Back


    I have to admit that sometimes in the dead of winter on cold, cold days, I get a bit claustrophobic. I feel cramped. Inside, it feels dark. It's almost like I can't breathe.

    So I put on my thickest coat over some layers and step outside. The first few moments are pretty cold - I curl in on myself, nearly tempted to run back inside to the waiting warmth. But, usually once I start walking, my blood starts flowing and I start to warm up a bit. So I keep going.

  • One Tree A Day ...

    In the office last week  I noticed a fellow arborist having a bad day. He was working on some research and was staring at the computer screen all morning, and he had a pretty bad headache. Attempting to ignore it wasn't helping. At lunchtime, he decided to go outside and take a walk through the nearby park.

    Before he left, it seemed like he was carrying the weight of the world on his shoulders. But when he came back, he was a different man. He walked with a lighter step. His headache had faded. He smiled more easily. And he took the rest of the day's challenges in stride, not letting anything frustrate him too quickly.

    It was a complete transformation.

  • Keep Coming, Old Man Winter – My Trees Will Keep Me Warm

    In two days, its the official first day of winter, I realize that each day going forward, temperatures will continue to get colder and colder.

    As I pile on the turtlenecks, the cable knit and the wool, I realize I'm adding so many layers it's like adding on half a person in clothes just to stay warm. Needless to say, I'm a "freeze baby," as they call it. It always takes me longer than usual to get warm on the coldest of days, like my body just refuses to adapt to the cooler temperatures.

    It's these nights when I'm curled up inside with a blanket by a warm fire that I think about my trees. Yep, that's right, my trees. They're outside, but they're helping keep me warm in the winter.
