Vascular Streak Dieback Update
Michael Martin, PhD • August 10, 2022
Researchers from Purdue University and Tennessee State University have released a new article providing a research update on Vascular Streak Dieback (VSD), tentatively identified as Rhizoctonia theobromae. As mentioned in the article, a great deal of research is still needed concerning VSD. In particular, the completion of Koch’s postulates, the criteria for establishing a causal relationship between a microbe and a disease. To date, no one has successfully completed Koch’s postulates with the fungus isolated from symptomatic redbuds. As previously mentioned, AmericanHort and HRI are working with researchers to support expanded efforts concerning VSD and will provide updates as they are available.
