    Description

    The reuse of plant pots by nursery growers has repeatedly been shown to be a method by which transfer of plant pathogens within a nursery will occur. More critically, this practice is an efficient pathway to infest landscape settings or habitat restoration sites by the out-planting of pre-symptomatic infected plant material. The transfer of water molds (oomycetes), such as plant pathogenic Phytophthora species, is a major threat to restoration projects and prevention of cross-contamination via pots should be a critical nursery operational control. Our research has established performance and efficacy criteria that demonstrate the risk can easily be managed by solarization of used pots.
