Something New in the Mix

Media

Researchers evaluated regionally available alternative substrates for ornamental crop production in the Pacific Northwest. The objective was to investigate the physiochemical properties of the substrate and ensure no biomass is phytotoxic to ornamental crops.

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.

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 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.

Treating Irrigation Water

Irrigation

Growers can minimize their risk of exposure to plant diseases and reduce pesticide use by ensuring that their irrigation water is free of Pythium and Phytophthora species. The authors discuss several different disinfestation methods for nursery and greenhouse operations.

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.

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.

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.
