Sudden Oak Death Publication Revised

Most recent information on stopping the spread of SOD included in this revised extension publication.

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.

Understanding Container Moisture

Container media

Researchers at Oregon State University have been studying how soilless substrates can be used together with moisture monitoring equipment to get the best results while reducing the need to irrigate. Topics specifically addressed include soilless substrate and water management.

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.

Live plant imports: the major pathway for forest insect and pathogen invasions of the US

Insects

A discussion about live plant imports as an important invasion pathway for non-native plant pests. The authors discuss the effect of current regulation, the need for updated regulation, and the recent and proposed changes to plant import regulation.

Sudden Oak Death and Phytophthora ramorum

Disease

A comprehensive guide for forest managers, Christmas tree growers, and forest-tree nursery operators in Oregon and Washington on sudden oak death, the disease caused by the recently introduced Phytophthora ramorum.

Natural Occurrence of Entomopathogens in Pacific Northwest Nursery Soil and Their Virulence to the Black Vine Weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidea)

Insect
The black vine weevil Otiorhynchus sulcatus (F.) is the primary insect pest of field and container-grown woody ornamentals in the Pacifc Northwest (PNW). These studies were conducted to determine the natural occurrence of soil-borne entomopathogens in PNW nursery soils and determine their virulence to black vine weevil.

Ecology of Metarhizium anisopliae in Soilless Potting Media and the Rhizosphere: Implications for Pest Management

Insects
Studies on the biological control of black vine weevil (BVW) in container-grown ornamentals were conducted to determine the persistence and ecology of Metarhizium anisopliae (Metchnikoff) Sorokin incorporated into peat and bark-based potting media with and without a crab meal amendment in container-grown Picea abies ‘Nidiformis.’
