Researchers at Oregon State University evaluated the potential of a remote soil-moisture-sensing technology in ornamental container production systems. The authors discuss the system they used, implications of the study, and their conclusions.
Growers can minimize their risk of exposure to plant diseases and reduce pesticide use by ensuring that their irrigation water is free of Pythium and Phytophthora species. The authors discuss several different disinfestation methods for nursery and greenhouse operations.
The goal of this Oregon State University affiliated research was to predict, through artificial inoculation, the symptoms and impact of Phytophthora ramorum on some western forest trees that have not yet been exposed to the pathogen in nature.
A systems approach for the production of healthy nursery stock. The manual, published by the Oregon Association of Nurseries, is divided into 3 main parts. A systems approach introduction, voluntary best practices for your nursery, and the next step: systems approach certification.
A comprehensive guide on P. ramorum. Topics discussed include; morphology, genetics, growth, distinguishing characteristics for identification, disease history, impacts in the forest, forest and wildland hosts and symptoms, and management and educational materials.
Oregon State University affiliated author discusses the top 10 tips for preventing disease in nurseries. Specific topics addressed include site selection and drainage, sanitation practices, disease free plant sources, plants in container, and irrigation.
Phytophthora species are some of the most problematic plant pathogens in nursery production systems. The Oregon State University affiliated author provides these top 10 tips which will help prevent this group of pathogens from taking hold.
Agricultural engineering specialist affiliated with the University of Connecticut discusses the benefits of using an ebb and flow irrigation system in a greenhouse environment. Examples of crops successfully grown using the ebb and flow system are provided.
The Oregon Department of Environmental Quality offers information about the importance of ground water and susceptibility to pollution. Topics discussed include groundwater sources, groundwater purity, harmful pollutants, and protecting groundwater.
An overview of the pesticide rules adopted by the Washington State Department of Agriculture in 1989. The new rules restricted pesticides containing one of more of the 18 active ingredients identified as having potential to contaminate ground water.
