Verticillium Albo Atrum

Extensive, unprecedented wilt and mortality of the highly invasive tree-of-heaven (Ailanthus altissima) occurred recently within mixed-hardwood forests in south-central Pennsylvania. Until this study, the cause of the epidemic was unknown. Verticillium albo-atrum was consistently isolated from symptomatic Ailanthus seedlings and trees in areas having high levels of mortality, whereas V. dahliae was isolated from small scattered patches of diseased Ailanthus. Inoculations of potted Ailanthus seedlings in the greenhouse, as well as canopy trees in the field, revealed that both V. albo-atrum and V. dahliae were capable of infecting Ailanthus, but V. albo-atrum was more pathogenic. All Ailanthus seedlings and canopy trees inoculated with V. albo-atrum died within 3 months. In contrast, Ailanthus seedlings and canopy trees inoculated with V. dahliae became symptomatic, but 84% were still living 1 year following inoculation. We conclude that the major cause of Ailanthus wilt within forests of south-central Pennsylvania is V. albo-atrum. Pending further studies, including risk analysis, V. albo-atrum may be considered as a possible biocontrol agent for invasive Ailanthus.

In this case study, we used point mapping data to evaluate long-term treatment of invasive tree-of-heaven (Ailanthus altissima). This study at the Buffalo National River included 21 project areas ranging in size from 0.02 to 11.3 ha and spanned five to eight years depending on the site. The control techniques varied depending on the year and included the application of herbicide, which also varied over the course of the study and included imazapyr, triclopyr, and triclopyr+fluroxypyr. Treatments during the first year reduced local A. altissima populations by an average of 66%. Long-term repeated treatments led to decreases of at least 90% in 70% of the project areas and at least 73% in 95% of the project areas. Only one project area was found to support no plants during the final treatment year. A. altissima increased at most project areas during an unusually wet year and was more likely to increase than decrease in intervals > 1 year with no treatment. Over the temporal and spatial scales of this case study, we observed high levels of control that will likely meet the specified levels and ecological benefits required in many similar efforts. Land managers must, however, make a long-term commitment of resources to achieve lasting control of this invasive species.
