Virus Diseases of Dahlia
Research Project at WSU

This project at Washington State University (WSU), headed by Dr. Hanu Pappu, researches the identification, control, and elimination of virus diseases in dahlias. The project grew out of a challenge grant provided by the estate of Evie Gullikson and was implemented through the American Dahlia Society in 1998.

In 2014 an endowment to this project by the Scheetz Chuey Charitable Foundation, in memory of Dr. Carl Chuey, significantly contributed to the continuation of this project.

Then in September of 2017 another endowment from the Scheetz Chuey Charitable Foundation enabled the creation of the Carl F. and James J. Chuey Chair for Dahlia Research and Development at WSU (currently held by Dr. Pappu) and the creation of a Dahlia Resouce Center.  In addition, donations from the Scheetz Chuey Charitable Foundation have enabled virus testing across the country.

Many local society and conference/federation activities are also helping members learn more about virus in dahlias. The video below is from a Summer Workshop held by the Federation of Northwest Dahlia Growers. Thanks for sharing!

The following tables list various documents, websites, videos, etc. regarding this research project.
