WVU experts see drought stress in yellow poplar trees

Two West Virginia University Extension specialists cite decline in yellow poplar trees in central West Virginia and eastern Ohio as examples of the potentially lasting effects of the 2024 drought.

David McGill, WVU Extension forest resources management specialist and professor, and Carlos Quesada, WVU Extension entomology specialist and assistant professor, note these regions are seeing widespread signs of stress this season.

The decline appears linked to last year’s significant drought and is compounded by repeated damage from yellow-poplar weevil and tuliptree scale.

What to look for

“There are several things you can look for when determining how the poplars are being affected, including delayed or sparse leaf-out, sometimes only in parts of the crown; a sticky residue honeydew and black sooty mold, indicating tuliptree scale activity, and/or same size holes in leaves caused by yellow-poplar weevil feeding.

“While these stressors may not be fatal on their own, together they increase the risk of decline and mortality, especially for older trees or those already weakened by other factors. Trees near homes, driveways or high-value areas should be watched closely.” David McGill, WVU Extension specialist and professor, forest resources management, WVU Davis College of Agriculture and Natural Resources

Managing stress

“Landowners may want to consider good agricultural practices, such as watering and fertilization to improve plant vigor.

“It’s also important to monitor insect pests such as yellow-poplar weevils and tuliptree scale because trees under stress can release volatile organic compounds that can attract insect pests. When infestation of insect pests are high, systemic pesticide treatments, such as imidacloprid, can manage wide range of insects that attack yellow poplar. This product is typically applied to the soil as a drench or root-zone injection, allowing the tree to absorb it through its roots and distribute it internally to control phloem-feeding insects.” – Carlos Quesada, WVU Extension specialist and assistant professor, entomology, WVU Davis College of Agriculture and Natural Resources
