Sudden Oak Death Publication Revised

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

Helping Plants Survive the Cold

Plant stress

A discussion about cold hardiness and effective plant protection strategies to minimize cold damage. The Oregon State University affiliated author addresses how plants become cold hardy, stages of hardiness, and effective protection.

An Express Route to Perfection

Breeding

A look into the world of plant breeding and the tools ornamental plant breeders have at their disposal to expedite breeding for specific traits. Topics addressed in the article include flow cytometry and molecular genetics.

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 Downside of Combination Fungicides

Greenhouse crops

A comprehensive discussion about the issues concerning pre-packaged fungicide mixes, which can elevate the risk of developing pathogens that are resistant to treatment. Strategies for avoiding resistance are included in the discussion.

Celebrating Cotoneaster

Breeding

Researchers evaluate selections from this sometimes underappreciated genus of landscape shrubs. Specific topics discussed in the article include landscape performance, disease resistance, and developing sterile cultivars.

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.

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.

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.
