University of Minnesota Forest Research Station in Cloquet, Minnesota where some of our forest disease research studies are carried out.

Profesor Blanchette with Dr. Norman Borlaug one of the most distinquished graduates of our department. He received the Noble Peace Prize, Congressional Gold Medal and the Presidential Medal of Freedom for his role in the green revolution and development of high-yield disease resistant wheat varities. Few people know that Dr. Borlaug also did work in Forest Pathology. His MS research at the University of Minensota was on determining the cause of red stain of boxelder.

Our research in Asia is helping poor rural farmers have a better life. Professor Blanchette in a Vietnamese village garden working on an agarwood project. This Aquilaria tree will produce a valuble resin and provide a new economy for the village.
