Taking Aim at Pests

Management

An initial report on research conducted on two intelligent, or precision, sprayers designed for use in the ornamental horticultural industry. The goal of this research is to develop efficient and affordable sprayers that use technology to respond to crop size and presence.

Monitoring From a Distance

Irrigation

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.

Adding to Growth

Soil

Researchers report on a study conducted to test the efficacy of soil additives in promoting plant growth and reducing mortality. The species included in the trial were Hydrangea macrophylla ‘Endless Summer’, Berberis thunbergii ‘Rose Glow’, and noble fir (Abies procera).

The Spread Offense Against Weeds

Weeds

A guide to help growers develop an effective weed management plan. Different strategies are presented on how to deal with annual and perennial weeds along with strategies for the growing issue of herbicide resistance in weeds.

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.

Managing Phytophthora

Plant disease

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.
