But through painstaking and tedious work, we have now been able to find two successful treatment options: a foliar application program designed for smaller trees, and a root flare injection suitable for large trees. And, although frustrating at times, it has been a very rewarding process.\u201d<\/p>\n<h3>Protecting Valued Beech Trees<\/h3>\n<p>This follows the discovery and publication of the research team\u2019s first successful foliar treatment option that successfully targets the invasive microscopic worm, a nematode (Litylenchus crenatae mccannii), causing BLD. Further, a new injectable treatment discovery shows excellent potential to protect larger beech trees for up to several seasons, staving off the defoliation and canopy dieback that results from severe infection.<\/p>\n<p>\u201cIt is important to keep our goals in mind with integrated pest management development,\u201d says <a href=\"https:\/\/www.bartlett.com\/staff\/matthew-borden-dpm\">Dr. Matthew Borden<\/a>, another plant pathologist on the research team. \u201cThis disease-causing nematode has spread at an astounding pace, quickly climbing into the ranks of other ecosystem-shifting catastrophes we have seen over the past century, like chestnut blight and emerald ash borer. Where containment and eradication are no longer feasible, we strive to develop IPM tools and techniques to protect individuals or groups of susceptible trees.\u201d<\/p>\n<p>While these discoveries and treatment options are not designed to address <a href=\"https:\/\/www.bartlett.com\/blog\/beech-leaf-disease-new-illnesses-impact-trees-too\/\">beech leaf disease<\/a> at the forest level, scientists at Bartlett now feel confident that we can protect many beech trees in places such as landscapes and arboreta where beech are valued as shade trees, historic specimens and represent genetically diverse collections that should be preserved for future work.<\/p>\n<figure id=\"attachment_7423\" aria-describedby=\"caption-attachment-7423\" style=\"width: 2560px\" class=\"wp-caption alignleft\"><img decoding=\"async\" class=\"wp-image-7423 size-full\" src=\"https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-scaled.jpg\" alt=\"weeping beech\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-scaled.jpg 2560w, https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-300x200.jpg 300w, https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-1024x683.jpg 1024w, https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-768x512.jpg 768w, https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-1536x1024.jpg 1536w, https:\/\/www.bartlett.com\/blog\/wp-content\/uploads\/2024\/06\/6812159_xl-WEEPING-BEECH-2048x1365.jpg 2048w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><figcaption id=\"caption-attachment-7423\" class=\"wp-caption-text\">New treatment strategies will help preserve valued beech trees and historic specimens in landscapes and gardens.<\/figcaption><\/figure>\n<h3>Beech Leaf Disease Research Continues<\/h3>\n<p>Over time, the scene will change, leading to the development of new resistant or tolerant beech varieties. In addition, Bartlett shall continue to develop new management strategies to conserve beech culture. The ongoing work of other scientists investigating the nematode\u2019s life cycle, how it spreads, and physiological impact on beech trees is also critical to finding future solutions.<\/p>\n<p>Bartlett\u2019s new treatment builds upon the work of scientists and arborists who developed treatments for Dutch elm disease in the 1970s and 80s, particularly the \u201cTree Doctor\u201d <a href=\"https:\/\/vtechworks.lib.vt.edu\/items\/f8119631-c4b9-46a9-8bfc-fde6d11c871c\">R. Jay Stipes<\/a>, professor emeritus at Virginia Tech, as well as a good friend and mentor to the Bartlett company. Jay was thrilled that the chemistry and tree injection techniques he helped pioneer to preserve many elm trees will find new success against yet another tree epidemic.<\/p>\n<p>\u201cBeech leaf disease is unlike any other widescale tree disease we have ever had to face,\u201d Dr. Borden adds. \u201cAs Jay likes to say, \u2018Tree medicine, as human medicine, is an uncertain art.\u2019 The nematode poses unique challenges we have had to overcome with out-of-the-box thinking. It takes a full year to properly evaluate a single treatment in the field, and we have conducted many field studies to test a wide range of management options and fine-tune treatments that show potential. The ongoing support of our research department, New England Division leadership, and especially Robert A. Bartlett, Jr. has made these discoveries possible.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research scientists at the Bartlett Tree Research Laboratories \u2013 the research arm of Bartlett Tree Experts \u2013 have broken new ground to protect beech trees by developing novel Integrated Pest Management (IPM) strategies to treat Beech Leaf Disease (BLD).
