Control of cyclamen mite on strawberries
Pear transit simulated in test: Four varieties of pears included in experiments to evaluate ability of containers to withstand damage and protect fruit
by Noel F. Sommer
Abstract Not Available – First paragraph follows: Nonwrapped jumble packed pears in cartons did not suffer more damage—when pads were compressed over the fruit by a tightly fastened lid—than wrapped fruit, in standard wooden boxes, in a series of laboratory tests.
Consumer acceptance surveys: Samples of experimental food products submitted to public taste-testing in attempt to estimate consumer acceptance
by Rose Marie Pangborn, Marion Simone
Abstract Not Available – First paragraph follows: Unless the public accepts the taste of a food product—regardless of how carefully prepared, nutritious, packaged, priced and available—the food is a complete failure.
Yield gain by delayed harvest: Continuing fruit growth of Yellow Newtown apples increased yield in tonnage and quality when harvested in late October
by Dillon S. Brown, Edward C. Koch
Abstract Not Available – First paragraph follows: Top quality Yellow Newtown apples can not be expected in the Watsonville district until late October but harvest usually begins about the third week of September.
Filbertworm injury to walnuts: Seasonal population trend of filbertworm moths as shown by trapping records may indicate severity of damage to crop
by A. E. Michelbacher, Arthur H. Retan, Stephen W. Hitchcock
Abstract Not Available – First paragraph follows: The flight of filbertworm moths during the early 1956 season was very small when compared to 1954 or to 1955 but after mid-July the moth catch—in five bait pans in an experimental walnut orchard near Gridley—began to mount. By season's end the severity of the infestation was second to that of 1954, when the infestation was the most severe encountered since investigations were started in 1944.
Sugar pine seedling survival: Investigations indicate seed storage conditions important factor affecting vigor and subsequent survival of seedlings
by Edward C. Stone
Abstract Not Available – First paragraph follows: Raising trees in the forest from planted seed—direct seeding—depends upon several factors.
Fumigation for cyclamen mite: Methyl bromide fumigation can give good control of pest on strawberries when treatment is properly timed and applied
by William W. Allen
Abstract Not Available – First paragraph follows: Fumigation of strawberry beds with methyl bromide can give better control—99% and higher—of the cyclamen mite than any other method, however, the treatment costs approximately $150.00 an acre. At the maximum, two applications are needed per year, and with perfected techniques a single fumigation probably will suffice. However, fumigation must be carried out carefully to obtain maximum control and must be done precisely to avoid damage to the plants because the dosage that will give good control is rather close to that which will give plant injury and the proper dosage varies with the temperature surrounding the plants. At any one dosage better control is obtained at higher temperatures, but at the same time there is an increase in the amount of injury.
Zinc deficiency of tomatoes: Corrective applications of zinc-supplying chemicals to soil tested in trials with transplanted and direct-seeded plants
by John C. Lingle, D. M. Holmberg, M. P. Zobel
Abstract Not Available – First paragraph follows: Canning tomatoes suffering from zinc deficiency were observed during the 1956 growing season near Linden, San Joaquin County, and in southern Sacramento County in addition to the known zinc deficient areas near Clarksburg in Yolo County. Apparently the disorder has a wider geographical distribution than was supposed.
Chemical weed control tests: Yields of flower seed increased in experiments with various chemicals to control annual weed pests costly to growers
by Jack L. Bivins, W. A. Harvey, Newton H. Foster
Abstract Not Available – First paragraph follows: Excellent control of annual weeds in flower seed plantings was achieved in Santa Barbara County test plots treated with Vapam, pre-emergence dinitro, methyl bromide, and Shell 20, during December 1954 and January 1955.
White paint for farm buildings: Characteristics of white paint prevent excessive heating of metal farm structures by radiation from sun, sky, environs
by T. E. Bond, C. F. Kelly, N. R. Ittner
Abstract Not Available – First paragraph follows: Part of a galvanized steel storage building in the Imperial Valley was painted during the summer of 1955—to study the influence of white paint on the thermal environment within a steel building and under metal animal shades—as part of a research project concerning the modification of the environment to improve animal gains.
Integrated management of water: Public districts provide a form of organization for integrating the management of surface and ground water
by Stephen C. Smith
