This new quarantine could impact ornamental growers shipping to Washington state.

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.

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.

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.

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.

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.

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.

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.

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.

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.
