The Washington Department of Agriculture will formally dedicate on May 11 a $750,000 greenhouse intended to support the tree fruit industry.

The 4,800-square-foot greenhouse is designed to help researchers search for ways to protect fruit trees from viruses. It is located at the Washington State University Irrigated Agriculture Research and Extension Center north of Prosser.

Construction was paid for by assessments on tree fruit nurseries.

The ribbon cutting will be 1 p.m.

Here is the state’s news release about the dedication.
