Looking through a window at a garden that is home to plants suspected of virus. It is positioned away from other gardens and allows its owner to observe and test its inhabitants.
Following are the articles, documents, and presentations that summarize our work on viruses in dahlias. Virtually all of the work reported between 2015 and 2025 reflects the efforts of the ADS Virus Team, the research activities of Professor Hanu Pappu and his team at Washington State University, and cooperative field research activities between those teams and the local ADS Societies and vendors across the country. Most of the work was made possible by the generous financial support of Scheetz-Chuey Charitable Foundation.
