This project aims to unravel the microbial mechanisms underlying natural suppression of root rot disease in Christmas tree plantations. By characterizing suppressive soils and identifying their antagonistic microorganisms, we seek to develop effective biological control strategies against this major threat to production. The research combines molecular analyses, microbial isolation, and greenhouse trials to demonstrate the biotic nature of disease suppression and assess its practical potential. Conducted in collaboration with Canadian growers, this project supports the long-term sustainability and profitability of the Christmas tree industry by promoting soil health and harnessing beneficial microbial communities for natural disease control.
