Suppressing pathogens in the greenhouse setting was the focus of this study. Dr. Zheng selected composted and non-composted organic materials with potential pathogen suppression properties and mixed these materials with other components to form a variety of growing substrates. Pathogenprone ornamental plants such as begonia were then subjected to selected growing substrates. Substrates containing vermicasting or pine bark showed disease suppression, however results were not consistent.
