New 2026 Updates On Lethal Bronzing Research
The Newest Research On Lethal Bronzing
Important 2026 Update on Lethal Bronzing Research to Share.
Most people have heard that lethal bronzing is spread to palms by a tiny insect — but until now, there has been very little explanation about what is actually happening inside the palm that causes it to die.
Gary Kennemer — a highly respected palm expert with decades of research and field experience — has just published new research in 2026 presenting a professionally published scientific explanation for how lethal bronzing leads to palm death.
The research suggests that palms may actually die because of their own extreme internal defense reaction — not just from the disease itself.
This is the first time this explanation has been formally published, and it may help reshape how this disease is understood moving forward.
This is real progress, and it gives everyone more clarity and hope than we’ve had before. Sharing this information is important as science continues developing and we move closer toward real solutions.
Share this with someone who has palm trees — the more people who understand the science, the better prepared we all are.

This work is published openly on an established scientific platform so that professionals, universities, and researchers worldwide can review it and build upon it moving forward.
About the Research Director - Gary Kennemer
Gary Kennemer has spent decades working hands-on with palm trees across a wide range of environments—growing, diagnosing, restoring, and managing palms in both residential and large-scale landscape settings.
While lethal bronzing has been recognized for many years, certain patterns observed in affected palms did not fully align with the commonly accepted explanation of how the disease leads to palm death. Over time, repeated field observations raised deeper questions: why some palms declined slowly, why others remained green while the growing point failed, and why timing of intervention appeared to influence outcomes.
Seven years ago, these unanswered questions led to a focused research effort to better understand what may be happening inside the palm itself during lethal bronzing infection—not just where the disease occurs, but how it progresses at a physiological level.
This work draws on decades of field experience, collaboration with plant-health professionals, and careful comparison of real-world outcomes across a wide range of palms. The result is a newly published scientific model proposing that palm mortality in lethal bronzing may be driven in part by an extreme internal defense response that ultimately compromises the palm’s ability to sustain its single growing point.
This new research development in 2026 does not claim a cure. Instead, it offers a clearer framework for understanding why palms fail the way they do—and why management decisions, timing, and future research directions are critical.
The paper was published openly in early 2026 so that researchers, universities, arborists, and plant-health professionals worldwide can review, evaluate, and build upon the findings as part of the broader scientific effort to better understand and manage lethal bronzing disease.
