This document summarizes a study assessing disinfectants for controlling Phytophthora ramorum, a fungal pathogen threatening nursery plants. The study is a collaborative project between Colorado State University and USDA-APHIS, testing oxidant disinfectants on greenhouse supplies, soil, and infected plants using a fungal surrogate. The goals are to determine efficacy on supplies and equipment, decontamination of soil, and effects on plants. Common oxidants like chlorine and hydrogen peroxide are examined, and their oxidation potentials and impacts on pathogens are discussed.
