Discusses what land use practices can impact riparian areas and the techniques landowners, volunteers, and professional resource managers can use to improve and protect riparian function.
Examines the eating habits of cows, sheep, horses, and goats, and explores how forage selection, pugging, trampling, and fencing contribute to a pasture's health and sustainability.
Traditionally, M. chitwoodi is controlled with
chemical nematicides, many of which risk
suspension for use on potatoes due to health and
environmental concerns. It is essential to develop
and refine alternative strategies for controlling
Columbia root-knot nematode now, so that
productive and profitable potato acreage will not
be lost if...
Phenoxy herbicides include 2,4-D, MCPA, Crossbow, Banvel,
Garlon, Weed-B-Gone, and Brush Killer. They also are the active
ingredient (2,4-dichlorophenoxyacetic acid, 2-methyl 4-chlorophenoxyacetic acid, triclopyr, or dicamba) in “weed and feed” and brush control products for use in the home landscape.
Cover crop selection and management depend on many factors, among them the cover crop’s ability to accumulate dry matter (i.e., residues) and nitrogen (N). Dry matter provides energy for soil organisms, contributes to soil organic matter, improves tilth, and acts as a sink for nutrients.

Root disease fungi attack and destroy the tree’s root system, resulting in growth loss, decay, death, or wind throw of infected trees. Trees with root disease also are more susceptible to pests, especially bark beetles. On the other hand, root diseases are a component of the forest ecosystem and play...

Fruit leather is a nutritious treat for young and old alike. The leathery sheets of dried fruit purée are easy to make at home using either fresh or canned fruits.
Curly dock (Rumex crispus L.) is a perennial. It does
not have creeping roots or rhizomes (Figure 1). Leaves
are oblong to nearly lanceshaped, often 12 inches or more
long, with wavy (crisped) margins (Figure 2). Erect, generally
unbranched stems up to 5 feet tall are produced in spring
and...
The objective of this series is to help improve the competitiveness of
Oregon’s wood products manufacturers. This can be achieved by fostering a companywide focus on and dedication to continuous quality improvement.
W. Edwards Deming (1982) described the “chain reaction of quality.”
1. Quality is improved.
2. Costs decrease due...
The goal for Part 2 is to build management understanding and

managers to commit to and support SPC training and implementation
if they do not understand what SPC is and how and why it works. This

The disease cycle for eastern filbert blight requires 2 or more years, including a 12- to 15-month latent period when no visible
symptoms can be detected. In the spring, spores are ejected forcibly (squirted) into the wind and rain. These spores then spread to
young, developing shoots. Infection occurs during...
Tomatoes are the most popular vegetable in the home garden. They’re a tasty fruit, and they supply vitamin C as well as many minerals needed for proper nutrition. They’re eaten fresh from the garden and processed in several ways for later use.
High-quality forages, such as alfalfa and grasses, are important for efficient milk production from dairy cows. Forages provide the effective fiber that is critical for good health and longevity. Inadequate
effective fiber in the cow’s diet is one reason for acidosis and milk fat
depression. Historically, when forage quality changed,...

Annual ryegrass (Lolium multiflorum Lam. or Lolium perenne L. ssp. multiflorum (Lam.) Husnot, also called Italian rye grass) is a cool season annual bunchgrass native to southern Europe. It is closely related to perennial ryegrass (Lolium perenne L.). Both are widely distributed throughout the world, including North and South America,...
Orchardgrass (Dactylis glomerata L.) is native to western and central Europe, but has been grown in North America for more than 200 years. In the 1830s, settlers in western
Virginia recognized the forage value of shade tolerant
D. glomerata plants growing in an orchard.
Tall fescue (Festuca arundinacea Schreb.) is a perennial, cool-season bunchgrass that is grown for pasture, hay, and silage. Native to Europe and North Africa, it was introduced from Europe to North and South America.
Perennial ryegrass (Lolium perenne L.), also called English ryegrass, is a cool-season perennial bunchgrass native to Europe, temperate Asia, and North Africa. It is widely distributed throughout the world, including North and South America, Europe, New Zealand, and Australia.
Clark is a hazelnut selection developed by Oregon State University.
Trees of this genotype are about 30 percent smaller than ‘Barcelona’ yet
have comparable yields to ‘Barcelona.’ This selection has good quantitative resistance to eastern filbert blight (EFB).
Harvest is 7–10 days earlier than‘Barcelona’ and nuts are free-husking.
Nuts have...
Three principal types of abiotic injury affect forests and woodlands in
Oregon: injury related to weather, to soil, and to human activity.
Abiotic injuries, also called abiotic diseases, can be found wherever
forests exist. They are, for the most part, initiated by nonliving factors in the environment, such as temperature...

This program explains that urban water pollution comes from a number of common sources, such as automobiles, lawn and garden fertilizer, and pet waste, and explores ways in which citizens can minimize their contribution to such pollution.
The overall objective of manure management should be to take as many excretable manure nutrients to the soil and have them used by plants for optimal crop yield. This reduces the need to purchase feed and inorganic fertilizer.
The OSU Extension Pesticide Properties Database is organized alphabetically by common name. Eight parameters describing pesticide physical and chemical properties are presented. The database includes pesticides that may not currently be registered for use in Oregon, but may have been used historically or may currently be registered for use in...
