The purpose of this report is to provide information on the adjustable-speed coupling system (ASCS) including: physical construction, principles of operation, application potential, and laboratory and field test results. In addition, comparison laboratory tests will be presented for conventional adjustable speed drives (ASDs). The ASCS has been tested at three...
Provides distribution, host-plant, life history, habits, signs of damage, and identification information for the cereal leaf beetle, first found in Oregon in 1999. Discusses methods of chemical and biological control. Includes information on California's quarantine on agricultural products from Oregon and four color photographs of the cereal leaf beetle and...
The role of resonant wind forcing in the ocean boundary layer was examined using an ocean large-eddy simulation (LES) model. The model simulates turbulent flow in a box, measuring ~100–300 m on a side, whose top coincides with the ocean surface. Horizontal boundary conditions are periodic, and time-dependent wind forcing...
Las malas hierbas compiten con las plantas cultivadas para el agua, la luz, y los nutrientes. Algunas también abrigan insectos y enfermedades que pueden dañar las plantas. Si usted controla las malas hierbas, sus plantas tendrán más oportunidad de crecer bien y producir a su

The cereal leaf beetle (CLB), a serious pest of cereals and grasses, was found in Oregon in 1999. As a result, California has imposed a quarantine on certain agricultural products from Oregon. CLB can cause considerable damage to small-grain crops. Yield losses of up to 23 percent in winter wheat...
Many garden and landscape plants
are susceptible to one or more plant
diseases. Diseases can reduce the yield
of fruit and vegetable crops and disfigure
ornamental trees, shrubs, and
flowers.
Young trees (those with a trunk diameter of less than 6 inches) can benefit greatly from regular applications of fertilizer. Research has shown that when these trees receive nitrogen fertilizer, they grow faster, develop a denser canopy, and stay green longer into the fall.
