Inert dusts for drywood termite prevention
Alfalfa wafers for dairy cows: No significant differences detected between alfalfa wafers and alfalfa hay in feeding trials with lactating heifers
by Don Addis
Abstract Not Available – First paragraph follows: Two pens of 10 cows each–all between 60 and 150 days past calving–were used in a three-part feeding trial with lactating cows.
Alfalfa and sorghum silages: Experiments indicate no difference between sweet forage-type sorghum and dual purpose-type when fed as silage to steers
by J. H. Meyer , G. P. Lofgreen , N. R. Ittner
Abstract Not Available – First paragraph follows: Silage from a sweet forage sorghum with a low grain-to-stalk ratio–variety Rex–was compared to silage from a dual purpose forage sorghum with a higher grain-to-stalk ratio–variety Hegari– and both were compared to alfalfa hay and alfalfa silage in feeding trials with beef steers. Two experiments were conducted; one with a limited concentrate ration, and the second, with a full feed of concentrate.
Abnormalities in tomato fruits: Effects of fruit-setting plant hormones and nitrogen level in relation to quality and storage life of tomatoes studied
by Randolph T. Wedding , Bernarr J. Hall , Morris J. Garber , Frank H. Takatori
Abstract Not Available – First paragraph follows: Spray applications of plant growth regulators, particularly 4-chlorophenoxyacetic acid–4-CPA–are widely used in some parts of California as an aid in obtaining set of tomato fruit during periods when the environment is unfavorable for natural fruit production. This practice is followed to a considerable extent in the tomato producing areas of San Diego County during the spring and fall months when night temperatures drop below the level favorable for the growth of pollen tubes and normal fertilization of the ovary.
Quality study on strawberries: Experiments with Shasta berries show harvested fruit should be protected against the effects of high field temperatures
by E. C. Maxie , F. Gordon Mitchell , Arthur Greathead
The following article is the first of two reports on Quality Studies with Strawberries. The second article will appear in the near future.
Control of drywood termites: Infestation or reinfestation after eradication prevented by treatment with inert dusts nontoxic to humans or animals
by Walter Ebeling , Robert E. Wagner
Abstract Not Available – First paragraph follows: Drywood termites–about as important in southern California as subterranean termites–have spread north to the San Francisco Bay region and Sacramento.
Peach tree borer on apricots: Trunk treatments for the control of major pest of apricots, prunes, plums, and peaches in the coastal growing districts
by Harold F. Madsen , Ross R. Sanborn
Abstract Not Available – First paragraph follows: Two insecticides–Thiodan and endrin –gave excellent control of the peach tree borer in studies made during the 1957 and 1958 seasons in an attempt to find a more effective insecticide than DDT. and one with a longer residual life.
Zinc effect on citrus, avocado: Large concentrations of zinc added to sand or soil cultures corrected mottle-leaf, increased leaf size and tree growth
by Joseph N. Brusca , A. R. C. Haas
Abstract Not Available – First paragraph follows: Zinc can stimulate the growth of citrus and avocado trees. Applied to the roots in nutrient solution at concentrations greater than required in sprays to correct mottled leaf symptoms, zinc will promote vegetative growth.
Micronutrients in valencias: Study made on the effects of nitrogen fertilization on the micronutrient concentrations in leaves of Valencia orange
by C. K. Labanauskas , T. W. Embleton , W. W. Jones , M. J. Garber
Abstract Not Available – First paragraph follows: Deficiency of micronutrients in citrus trees is an important problem in central and southern California orchards.
Evaporated milk in California: Analysis made of in-plant costs and relationship between the unit cost of processing and output rate of plant production
