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.

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.

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.

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.

Confirmation of hyridity using GISH and determination of 18S rDNA copy number using FISH in interspecific F1 hybrids of Tecoma (Bignoniaceaea)

Breeding

This study on interspecific hybridization in Tecoma Juss. was conducted to develop novel forms for the nursery industry. The selection of species used in the study included T. garrocha, T. stans, T. guarume, and T. capensis.

Protecting Container-grown Plants

Container

Pests and pathogens are a threat for growers that produce containerized nursery stock. The authors discuss how to reduce these threats by considering the type of containers and growing media they use, where they are sourced, how they are handled, and how they are stored.

Becoming Your Own Prophet of Profit

Nursery Crops

Oregon State University affiliated authors discuss production costs and product pricing which has a great impact on the profitability of a nursery business. Specific topics addressed include identifying plant costs and preparing for the future.

Breaking it Down

Management

As interest in compost grows, so does the need to better understand what compost is, and to learn about the limitations and advantages of particular composts. Suggestions are provided for how to use compost testing as a tool to get greater value from compost use.

Reducing Phytophthora

Plant Disease

Phytophthora species are some of the most problematic plant pathogens in nursery production systems. The Oregon State University affiliated author provides these top 10 tips which will help prevent this group of pathogens from taking hold.

Simple Linear Regression and Reflectance Sensitivity Analysis Used to Determined the Optimun Wavelengths for the Nondestructive Assessment of Chlorophyll in Fresh Leaves Using Spectral Reflectance

Management
This study was conducted to 1) evaluate whether simple linear regression in combination with reflectance sensitivity analysis can be used to determine optimal wavelength (OW) for Chl assessment using reflectance; and 2) evaluate the importance of using OW in the development of Chl-related reflectance indices.
