Energy, public opinion, and public policy—a survey of urban, suburban, and rural communities
by Edward J. Blakely
pp4-5, doi#10.3733/ca.v030n08p4
Abstract
Not available – first paragraph follows: The California lifestyle depends on easy access to in-expensive energy. Continued rising energy costs probably will mean drastic alterations in that lifestyle and consequently in the growth patterns of the state's communities. It seems apparent, furthermore, that public attitudes about the energy crisis - its causes and consequences — will influence state and national policy.

Handling seed cotton modules without pallets
by Robert A. Kepner, Robert G. Curley
pp6-8, doi#10.3733/ca.v030n08p6
Abstract
Not available – first paragraph follows: Pallets used in the module system for handling and storing seed cotton are awkward to manage, are easily damaged, and represent a large capital investment. The Reynolds module mover, which first became commercially available in 1975, picks up and hauls cotton modules made directly on the ground. It is similar to haystack movers that have been available for several years. Palletless modules will remain intact through several loading and unloading cycles with the Reynolds mover.

Biological control of crown gall
by William J. Moller, Milton N. Schroth
pp8-9, doi#10.3733/ca.v030n08p8
Abstract
A non-gall-forming bacterium may provide the much-needed biological method of controlling this serious disease in new deciduous fruit orchards.

Root and crown rot of cherry trees
by Srecko m. Mircetich, Wallace R. Schreader, William J. Moller, Warren C. Micke
pp10-11, doi#10.3733/ca.v030n08p10
Abstract
Not available – first paragraph follows: Decline and death of bearing cherry trees resulted in an estimated loss of 22 percent of all sweet cherry trees in San Joaquin County during 1973-75. During 1972-74 heavier than normal rainfall occurred, especially during late winter and early spring. In 1975 some orchards were almost 100 percent affected with crown and root rots. In previous years crown and root rot diseases were always prevalent in cherry orchards on poorly drained soil, but in 1975 these losses were excessive, and growers were forced to remove many acres of declining and dead trees.

Sprinkler application of a sugar beet herbicide
by David W. Cudney, George F. Worker, James E. Hill
pp12, doi#10.3733/ca.v030n08p12
Abstract
Not available – first paragraph follows: A new method of applying a preemergence herbicide in sugar beets by sprinklers may reduce costs to growers by eliminating power incorporation. More than 40 percent of Imperial Valley's 65,000 acres of sugar beets are normally sprinkled to achieve germination. Ro-Neet (cycloate) is commonly incorporated by power equipment as a preplant treatment to control troublesome weeds in sugar beets, whether germinated by sprinkler or by furrow irrigation.

Fungicides for control of cucurbit powdery mildew
by Albert O. Paulus, Robert A. Brendler, Jerry Nelson, Tom Whitaker, Bernarr J. Hall
pp13, doi#10.3733/ca.v030n08p13
Abstract
Not available – first paragraph follows: Powdery mildew caused by the fungus Sphaerotheca fuliginea (Schlecht.) Poll. is responsible for reduced cantaloupe, cucumber, and squash yields in many production areas. Trials were initiated to test several new materials for control of the fungus.

Increased insecticide use in cotton may cause secondary pest outbreaks
by Robert A. Van Steenwyk, Nick C. Toscano, Gregory R. Ballmer Ken Kido, Harold T. Reynolds
pp14-15, doi#10.3733/ca.v030n08p14
Abstract
Not available – first paragraph follows: Pink bollworm, Pectinophora gossy-piella (Saunders), invaded southern California's lower desert valleys during the 1966 cotton growing season. Because of the widespread, damaging infestation levels, multiple applications of broad-spectrum insecticides have been used to reduce losses. These insecticides have proved extremely toxic to beneficial insect populations and are suspected of inducing outbreaks of other cotton pests.

Use of fluorescent dye to whiten wool

by Mary Ann Morris, Barbara W. Mitchell
pp237-245, doi#10.3733/hilg.v30n08p237
Abstract
The whitening effect of a fluorescent dye applied from organic solvents to white wool was investigated. Optimum conditions for applying C. I. Fluorescent Brightening Agent #68 from perchlorethylene and Stoddard solvent at room temperature were developed. Visual evaluation in daylight and under ultraviolet light showed a marked improvement in whiteness after application of the dye to white wool fabrics. The fastness of the dye to conditions encountered during use was found to be satisfactory.
