It was a great day for WSDA when our agency dedicated its new greenhouse at Prosser on May 11.

Representatives from the fruit tree industry, WSU, and WSDA were on hand as was a radio reporter and writer from the Good Fruit Grower magazine. Rep. Brad Klippert, R-Kennewick, also attended.
Director Derek Sandison congratulated the partners who helped this project come together, including:
- Current and past WSDA employees who advocated for the 4,800 square-foot greenhouse.
- Key fruit tree nurseries, including three nursery owners who serve on our Fruit Tree Advisory Committee.
- WSU staff who supported the greenhouse and actually built it.
For decades, WSDA rented a smaller greenhouse from WSU at their research station.
“This new, modern greenhouse gives us an increased capacity to test registered mother trees as clean nursery stock at a rate greater than we’ve been able to do in the past,” Derek said.
Disease-free plant stock
Our new greenhouse, designed by Horticultural Services of Lake Tapps, will be used for indexing fruit trees for harmful plant viruses. Washington is among only a handful of states with such a program. It allows nurseries to offer virus-tested, disease-free stock to orchardists and fruit producers.

Dr. Lauri Guerra, who manages our greenhouse as coordinator for fruit tree certification, says the greenhouse is a significant tool to improve testing to support industry.
“It allows us more flexibility to test trees throughout the year,” said Lauri, who came to WSDA in 1999 after earning a PH.D in Virology at UC Davis.
Project achieves fruition
Segun Akinbade, WSDA’s nematode identifier in our Prosser lab, also praised the benefits of the greenhouse which is fully automated and features improved temperature and irrigation controls. Each growing bay is computer-controlled to maintain temperature ranges at which different fruit tree pathogens thrive.
“It was wonderful to see everyone come support the new greenhouse and our certification program,” said Cindy Cooper, manager of the Plant Services Program. Cindy has made numerous trips to Prosser in the past two years to check on this project.
“We’re lucky to have strong partnerships with industry and WSU. It couldn’t have been a better day.”
In summary: WSDA’s Plant Services Program culminated years of planning and work by dedicating a brand new greenhouse at the WSU research center in Prosser on May 11. Learn more about the day, the project and the people behind it.
