Manipulating vineyard weeds with herbicides
by
Dean R. Donaldson , Clyde L. Elmore , Sherri E. Gallagher , John A. Roncoroni
pp15-16, doi#10.3733/ca.v042n03p15
Abstract
Abstract Not Available – First paragraph follows:
Vineyard weeds vary from location to location but often include a broad complex of 15 to 25 species. Most vineyard managers control weeds by applying herbicides or by plowing a strip down the crop row. Weeds between the rows are controlled by discing or mowing (mechanical or chemical) in a total weed control program. In some vineyards, annual or perennial grass or broadleaf cover crops are planted between the rows.

Stable fly activity on California dairies
by
Bradley A. Mullens , Jeffery A. Meyer , Shirl E. Bishop , Thomas A. Shultz
pp20-21, doi#10.3733/ca.v042n03p20
Abstract
Abstract Not Available – First paragraph follows:
Stable flies are blood-sucking pests of cattle, horses, and other warm-blooded animals in many parts of the world. The pain associated with stable fly bites upsets livestock feeding patterns, reducing weight gains, feed efficiency, and milk production. Although few studies have been done on such losses, reductions of up to a half pound a day in weight gain and 30 to 40 percent in milk yield have been observed.

Weed control by subsurface drip irrigation
by
Stephen R. Grattan , Lawrence J. Schwankl , W. Thomas Lanini
pp22-24, doi#10.3733/ca.v042n03p22
Abstract
Abstract Not Available – First paragraph follows:
Most California growers on irrigated farmland rely on the application of synthetic chemicals to control weeds. Although these chemicals are effective, there are increasing concerns about the long-term effects such materials may have on the quality of soil and water.

Drainage system performance after 20 years
by
Mark E. Grismer , Ian C. Tod , Frank E. Robinson
pp24-25, doi#10.3733/ca.v042n03p24
Abstract
Abstract Not Available – First paragraph follows:
As part of a study of the longevity and effectiveness of clay, bituminous fiber, and concrete drainage pipes, several pairs of these pipes were installed in a heavy clay soil at the Imperial Valley Agricultural Center at El Centro, California in January 1964. Drain lines were laid at a depth of 7 feet and a spacing of 120 feet. Bituminous-fiber drains were installed in a fiberglass envelope; washed gravel was used to enclose the clay and concrete pipes.

The Immigration Reform and Control Act: IRCA's effects on large farms
by
Philip L. Martin , Stephanie Luce
pp26-28, doi#10.3733/ca.v042n03p26
Abstract
Abstract Not Available – First paragraph follows:
In August-September 1987, soon after the Immigration Reform and Control Act began to affect agriculture, we conducted a survey to determine its effects on California farm employers. Our farm labor survey was mailed to the members of several farm organizations, and the responses were analyzed by the University of California, Davis.

Initial effects of the new immigration law on California agriculture
by
Howard R. Rosenberg , Jeffrey M. Perloff
pp28-32, doi#10.3733/ca.v042n03p28
Abstract
Abstract Not Available – First paragraph follows:
The Immigration Reform and Control Act (IRCA) of 1986 prohibits the employment of persons not legally entitled to work in the United States. It imposes on all employers new hiring and record-keeping obligations, with stiff fines for noncompliance. It creates a means of obtaining legal resident status, particularly for “special agricultural workers” (SAWS) employed during 1985-86 in fruits, vegetables, and other perishable commodities specified by the Secretary of Agriculture.
