Small and Mite-y

Nursery crops

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.

Helping Pests Meet Their Match

Insects

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.

Finding the Answers

Plant disease

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.

Phytophthora ramorum

Plant disease

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 Economy of Water

Irrigation

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.

Slime and Punishment

Management

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.

Susceptibility of Oregon Forest Trees and Shrubs to Phytophthora ramorum: A Comparison of Artificial Inoculation and Natural Infection

Plant disease
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.

Safe Procurement and Production Manual

Nursery crops

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.

Phytophthora ramorum

Plant disease

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.

Phytophthora ramorum Colonizes Tanoak Xylem and Is Associate with Reduced Stem Water Transport

Plant disease
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.
