Deciding when to treat for 12-spot beetles in snap beans = Cómo y cuándo controlar al escarabajo de 12 manchas en los ejotes (vainitas, habichuelas)

Creator:: Santamaria, Luisa, Hernandez, Jose, Gonzales, Alejandro, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Discusses ways to apply integrated pest management principles to management of 12-spot beetles (Western spotted cucumber beetle) in snap beans. Covers pest description, crop damage, biology and life history, scouting and thresholds, and sweep net sampling. Presents information in English and Spanish.
Resource Type:: Technical Report

Conservation of arthropod natural enemies in broccoli with relay strip-cropping

Creator:: McGrath, Daniel M. (Daniel Morton)
Abstract:: Relay strip-cropping combines two vegetation management tactics, under-sowing and strip-management. In this study conducted from 1994 though 1997, a cover crop seed-mixture containing oats (Avena sativa L. var. "Monida"), common vetch (Vicia sativa L.), red clover (Trifolium pratense L.), annual ryegrass (Lolium multflorum Lam.), and buckwheat (Fagopyrum esculentum Moench) was...

Managing 12 spot beetles in snap beans : with fewer chemicals and less risk of crop damage

Creator:: McGrath, Daniel M. (Daniel Morton), Peachey, Ronald Edward, and Oregon State University. Extension Service
Abstract:: Many buyers of processed vegetables are responding to consumer concerns by demanding that producers have an effective environmental stewardship program and reduce pesticide use. Snap bean producers have an opportunity to meet these demands. The snap bean and 12 spot beetle interaction is relatively simple. Methods for determining risk of...

A guide to multifunctional hedgerows in western Oregon

Creator:: Hobbs, Jude, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Hedgerows, also known as shelterbelts or windbreaks, are rows of trees, shrubs, and low-growing plants that divide or border fields and/or suburban lots. In England, many farms are surrounded by ancient hedgerows that conserve soil and water, provide a home to wildlife, and serve as barriers. In the United States,...

Cover crop dry matter and nitrogen accumulation in Western Oregon

Creator:: Sattell, Robert, Buford, Thomas, Murray, Helene, Dick, Richard, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: 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.
Resource Type:: Technical Report

Rapeseed (Brassica campestris/Brassica napus)

Creator:: Sattell, Robert, Dick, Richard, Ingham, Russ, Karow, Russell S., Kaufman, Diane, McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Rapeseed is grown for its oil and meal, and as a cover crop. Rapid fall growth captures part of the available soil nitrogen, which otherwise might be lost to leaching, and provides good ground cover over winter.
Resource Type:: Technical Report

Red clover (Trifolium pratense)

Creator:: Sattell, Robert, Dick, Richard, Hemphill, Delbert D., McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Red clover is used successfully in Oregon as a fall-planted cover crop and green manure in rotations with vegetable crops.
Resource Type:: Technical Report

Subterranean clovers (Trifolium subterraneum)

Creator:: Sattell, Robert, Dick, Richard, Hemphill, Delbert D., McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Subclovers are used for forage and hay and have been used successfully in Oregon as fall-planted and relay interplanted cover crops in annual rotations. They are capable of accumulating substantial amounts of N, a portion of which is available to the following crop. Rapid growth suppresses weeds in spring.
Resource Type:: Technical Report

Sudangrass and sorghum-sudangrass hybrids (Sorghum bicolor L.)

Creator:: Sattell, Robert, Dick, Richard, Ingham, Russ, Karow, Russell S., McGrath, Daniel M. (Daniel Morton), and Oregon State University. Extension Service
Abstract:: Sudangrass and sorghum sudangrass crosses are used as warm season cover crops, forage, and silage. When used as a cover crop, their fibrous roots and organic matter contributions improve soil structure; and their rapid, dense growth suppresses weeds.
Resource Type:: Technical Report

Common vetch (Vicia sativa L.)

Creator:: Sattell, Robert, Dick, Richard, Luna, John, McGrath, Daniel M. (Daniel Morton), Peachey, Ronald Edward, and Oregon State University. Extension Service
Abstract:: Common vetch is a viny, succulent, annual legume attaining a height of 24 inches when planted alone. It grows taller when planted with a tall companion crop that provides structural support for climbing.
