In 2019, the federal government allocated $68.9 million to build a new GGRU facility in Geneva. The funding will create a new lab for USDA Agricultural Research Service scientists. Dr. Zhong says the new yet unnamed facility is expected to open in three years. Cornell will be involved as a partner in the facility and research once the lab is built (Gan-Yuan Zhong).
