A Guide to Hedgerows: Plantings That Enhance Biodiversity, Sustainability and Functionality: Hedgerows are living fences with the ability to grow food, shelter wildlife, save water, manage weeds and look beautiful all year round. Study the many benefits of hedgerows, and learn what you need to know to plant your own living fence.
Nonlethal Bird Deterrent Strategies: Methods for reducing fruit crop losses in Oregon: Bird predation is a significant threat to marketable yields in fruit crops. Loss estimates are about 10% to 20% in blueberries, 5% to 30% in cherries, and 5% to 10% in grapes. However, some vineyard sites have reported up to 50% losses. There are many avian deterrents on the market. Success with deterrents varies by site and bird species. In most cases, the best results come from a multipronged approach.
An Introduction to Ground Beetles of the Willamette Valley: This narrated slideshow provides a brief introduction to carabid beetles, including life cycle, anatomy, common species, and sampling methods.
Biodegradable Plastic Mulch and Suitability for Sustainable and Organic Agriculture: Polyethylene mulch is environmentally harmful and expensive to dispose of: discover biodegradable plastic mulch as a viable alternative.
Biocontrol of Spotted-wing Drosophila: Multiple biological control agents target SWD, including predators, parasitoids, nematodes and microorganisms such as fungi and bacteria. Predators ambush and eat SWD, removing a substantial portion of them from the production system.
Spotted Wing Drosophila: A Quick, 7-Step Guide to Detecting SWD Larvae in Fruit: This brief guide illustrates how to test fruit for the presence of larvae from the Spotted Wing Drosophila.
A Detailed Guide for Testing Fruit for the Presence of Spotted Wing Drosophila (SWD) Larvae: This detailed guide illustrates how to test fruit for the presence of the Spotted Wing Drosophila larvae by crushing the fruit, immersing it into a salt or sugar solution, and examining the fruit debris for larvae and pupae.
Recognize Fruit Damage from Spotted Wing Drosophila: This publication shows damage caused by SWD on blueberries (Duke), raspberries (Malahat), strawberries (Seascape), cherries (Bing, Montmorency, and Rainier), and grapes (Pinot Noir, Chardonnay).
Host Range and Characteristics Affecting Fruit Susceptibility to Spotted-wing Drosophila: Spotted-wing drosophila (SWD) can develop on a wide range of cultivated and wild, soft-skinned fruits. This complicates pest management because SWD populations can move among several hosts with different ripening times throughout the year, allowing them to survive and reproduce in many environments.
Noncrop Host Plants Used by Spotted-wing Drosophila: Dense vegetation surrounding commercial fields can create a suitable habitat for spotted-wing drosophila due to the shade, coolness and humidity it provides during the summer. Noncrop habitat may contribute to SWD pest pressure and affect sustainable integrated pest management strategies.
Cultural Control Strategies to Manage Spotted-wing Drosophila: Cultural controls can reduce spotted-wing drosophila population pressure by modifying the microclimate within the crop so that the environment does not promote SWD reproduction and survival.
Wireworm: Biology and Nonchemical Management in Potatoes in the Pacific Northwest: Wireworms are among the most destructive of soil insect pests. This publication explains the wireworm life cycle and describes a program for monitoring and risk assessment. Nonchemical management methods are suggested, including crop rotation, soil drying, flooding, cultivation, resistant varieties, soil amendments, early harvest, trap crops, and biological control. Includes photos for pest identification.
Integrated Clubroot Control Strategies of Brassicas: Nonchemical Control Strategies: Clubroot (causal organism, Plasmodiophora brassicae) is a major soilborne disease of brassica crops in the Willamette Valley. It’s incidence and severity is increasing due to a high demand for brassicas that has resulted in more land dedicated to growing these crops and to short rotations. This publication provides information on integrated control strategies to minimize crop loss.
What's Wrong with my Potato Tubers? Diagnosing Tuber Abnormalities in Western Oregon and Washington: Describes and illustrates (color photos) tuber damage caused by insect pests, plant diseases, and physiological disorders.
Organic Management of Flea Beetles: Flea beetles are common garden pests found throughout the Pacific Northwest. Flea beetle feeding on plants in the Brassicaceae and Solanaceae families can scar foliage and potato tubers, leading to reduced marketable yields and potential total crop loss. This publication introduces growers to current organic management options, including cultural control techniques such as trap crops, companion plants, and mulches; biological control; and approved organic pesticides.
