The Spread Offense Against Weeds

Weeds

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.

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.

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.

Finding the Answers

Plant disease

Correctly diagnosing a plant problem for nursery growers can be challenging. However, the right diagnostic resources coupled with an early and appropriate diagnosis can prevent pests or pathogens from spreading, saving time and money.

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.

A Challenge for the New Millennium

Culture

John Lambrinos, assistant professor of horticulture with Oregon State University, discusses how the fields of horticulture and restoration ecology can work together in a mutually beneficial way to improve the environment.

Slime and Punishment

Management

No matter how small, slugs and snails can cause huge headaches for growers. Fortunately, there are many ways these pests can be managed and eliminated. The author discusses the importance of and the different factors involved in a good integrated pest management plan.
