Genome Size Estimates and Chromosome Numbers of Callicarpa L. (Lamiaceae)

Breeding
A report on Oregon State University affiliated research, which was conducted with the purpose of documenting chromosome number and genome size of Callicarpa species to add to the available information on the genus.

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.

When Mite Makes Right

Nursery Crops
Comprehensive guide on how to control spider mites in the nursery biologically by using predatory mites. Predatory mites are tiny little animals whose appetite for spider mites makes them a great tool for suppressing and managing mite outbreaks.

Evaluation of Application Technologies of Entomopathogenic Nematodes for Control of the Black Vine Weevil

Insects
Studies were conducted to determine the efficacy of three species of entomopathogenic nematodes (Heterorhabditis marelatus, Heterorhabditis bacteriophora, and Steinernema riobrave) applied in infected host cadavers or as aqueous applications for black vine weevil larval control.

A Technique for Continuous Mass Rearing of the Black Vine Weevil, Otiorhynchus sulcatus

Insects
Experiments were performed to determine if 1) O. sulcatus larval survival and development increased with a standard or improved diet and 2) whether O. sulcatus eggs could be stored for up to 4 weeks at 4 °C without significant reductions in larval survival and development.

Efficacy of Metarhizium anisopliae as a Curative Application for Black Vine Weevil (Otiorhynchus sulcatus) Infesting Container-Grown Nursery Crops

Insects
The objectives of this study were to determine the efficacy of a curative drench application of M. anisopliae for controlling black vine weevil (BVW) larval infestations in container-grown nursery plants and the effect of temperature on the rate of fungal growth and speed of kill.

Phenolic Composistion of Basil Plants is Differentially Altered by Plant Nutrient Status and Inoculation with Mycorrhizal Fungi

Management
Four cultivars of basil were inoculated or not with the arbuscular mycorrhizal fungus (AMF), Rhizophagus (formerly Glomus) intraradices (Schenck & Smith) Walker & Schubler and grown with a fertilizer to access whether 1) P availability and inoculation with AMF influences the phenolic composition of basil; and 2) treatment effects on phenolic composition are related to plant nutrient status.
