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.
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...
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...
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 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.
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.
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.
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
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.
