Non Technical Summary
Greenhouse growers are increasingly adopting wood-based soilless substrates to meet sustainability and supply challenges. However, they face uncertainty about how these substrates affect plant health and disease control. This project evaluates how engineered wood components influence soilborne diseases and the effectiveness of biopesticides. Findings will inform growers, industry stakeholders, and researchers on best practices, ultimately improving plant production, reducing pesticide use, and supporting economic and environmental sustainability in greenhouse systems.

Goals / Objectives
This project aims to understand how wood-derived soilless substrates influence plant disease development and biofungicide efficacy, supporting sustainable greenhouse production. Specifically, it seeks to:1) Survey wood substrate components for effects on soilborne disease severity.2) Assess how wood processing and preconditioning affect plant-pathogen dynamics.3) Evaluate how wood substrates influence the performance of biofungicides on disease incidence and severity.
Project Methods
A systems-based, multidisciplinary research strategy will be employed:- Laboratory and greenhouse trials assessing disease severity and biofungicide efficacy.- Physiochemical analyses of substrate components.- Evaluation of preconditioning treatments of wood substrates.- Pathology assays with model crops (cucumber, lettuce, chrysanthemum) and Pythium.- Statistical analysis using ANOVA and mixed models.- Engagement with industry for feedback and dissemination.- Holistic mentoring of graduate and undergraduate students in this area of science and extension.
