Oregon State University researchers discuss their investigation of a new microscopic pest, eriophyid mites, which causes damage to linden trees. Identification and detection, distribution and behavior, and damage and control strategies are specifically discussed.
Pest management researcher discusses the Interregional Research Project No. 4, commonly known as IR-4, a federally funded program that assists growers of ornamental horticulture crops in obtaining safe and effective pest management tools.
Correctly diagnosing a plant problem for nursery growers can be challenging. However, the right diagnostic resources coupled with an early and appropriate diagnosis can prevent pests or pathogens from spreading, saving time and money.
Plant pathologists track where Phytophthora ramorum came from and how it has managed to spread. The author specifically discusses Phytophthora ramorum clones and mating types and tracking the migration of the pathogen.
The Oregon State University affiliated authors strive to answer the question of whether plant physiology and breeding research can work collectively to develop more water-efficient and drought tolerant plants that will benefit the green industry.
No matter how small, slugs and snails can cause huge headaches for growers. Fortunately, there are many ways these pests can be managed and eliminated. The author discusses the importance of and the different factors involved in a good integrated pest management plan.
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.
For this study, researchers sought to determine if Phytophthora ramorum regularly colonizes the secondary xylem of tanoak (Lithocarpus densiflorus), and to quantify and visualize the frequency and extent of sapwood colonization.
