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.
Fava bean is used as a winter or spring cover crop, green manure, silage, forage, hay, and vegetable. It is capable of producing large amounts of dry matter and accumulating large quantities of nitrogen (N), part of which is available to subsequent crops.
The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures
of Bacillus thuringiensis-based microbial and selected chemical insecticides was
studied under laboratory and field conditions. Joint actions (synergism, additivity and
antagonism) of these mixtures were determined for both egg and larval stages. Higher
rates of microbial control agents (MCAs),...
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.
Crimson clover may be used as a cover crop, green manure, pasture, or hay. It often is used as a winter annual cover crop in annual rotations. It has been used successfully in reduced-tillage farming systems, and in orchards and vineyards where it can be managed to reseed itself.
Field pea can be used as a cover crop, green manure, forage, hay, and silage. Hay is good quality, but pea is more succulent than vetches and more difficult to cure. Regrowth after mowing or grazing is poor.
The western cherry fruit fly, Rhagoletis indifferens
Curran, was studied to determine the suitability of the
sterile insect technique for its control. To obtain
insect material, field collection of maggots is preferred
to sifting of soil or rearing on artificial diet.
The western cherry fruit fly is strictly univoltine;
only...
The overarching objective of this paper is to identify how the three tiers of human well-being (i.e., economics, ecosystems, and social) are linked to healthy landscapes and a species-rich ecosystem mediated by healthy cougar populations. Does the cougar help mitigate Oregon’s Lyme disease, chronic wasting disease (CWD), or elements of...
Cereal rye is an erect annual grass with greenish blue, flat blades and an extensive fibrous root system. It resembles wheat, but usually is taller (3–5 ft) and tillers less. Flowering is induced by 14 hours of light in spring.
