Rosy apple aphid control tests: Dormant oil plus phosphate compounds applied to control the overwintering eggs more efficient than spring foliage sprays
by Harold F. Madsen, Blair J. Balley
| Full text HTML  | PDF  
Rosy apple aphid—perhaps the commonest aphid found on apples in California—can be a very destructive pest if not controlled.

New control for alfalfa aphid: Systemic insecticide protects insect enemies of aphid, allows compatibility of chemical treatment with biological control
by Vernon M. Stern, Robert van den Bosch, Dewey Born
| Full text HTML  | PDF  
There is little doubt that the insecticides parathion, malathion, and TEPP prevented a widespread devastation of California's alfalfa industry following the 1954 appearance of the spotted alfalfa aphid—Therioaphis maculata (Buckton) but the materials also proved to be toxic to insect enemies of the aphid.

Boom and broadcast sprayers: Comparative field and laboratory study of spray distribution as applied by two types of sprayers on spotted alfalfa aphid
by Jack E. Dibble, R. G. Curley, N. B. Akesson

At approximately the same time that maximum control of the spotted alfalfa aphid—Therioaphis maculata (Buckton)—became of great importance, a new boomless sprayer for broadcasting insecticides became popular in some areas.

Plastic shelters for new lambs: Protection from weather during first few days after birth reduced losses in tests during January-March lambing season
by D. T. Torell, C. F. Kelly, T. E. Bond, W. C. Weir
| Full text HTML  | PDF  
Losses of range-born lambs—in some instances as high as 90%—have resulted from severe rainstorms during the lambing season on the north coast sheep ranges. Conventional protective range shelters or barns usually are economically unfeasible because of the cost. An inexpensive, experimental polyethylene plastic shelter was tested at the Hopland Field Station in southern Mendocino County during the 1957 lambing period, when 19″ of rain fell. The percentage of lambs saved that season was higher than in any previous year since the Field Station was established in 1951.

Nitrogen-fixation by deerbrush: Greenhouse experiments suggest deerbrush has root nodules like leguminous plants with nitrogen-fixing properties
by James Vlamis, A. M. Schultz, H. H. Biswell
| Full text HTML  | PDF  
Recent studies indicate that nodules on the roots of deerbrush—Ceanothus integerrimus—supply this species with a source of nitrogen and might greatly improve growth of the plant, especially in soils where nitrogen is a limiting factor.

Aureomycin in livestock feed: Antibiotic in form of a prepared alfalfa-base pellet added to ration in feeding trials with weaner calves and yearlings
by Blaine McGowan, Reuben Albaugh
| Full text HTML  | PDF  
Recently beef and lamb producers have adopted the practice—formerly restricted to poultry and swine producers—of adding antibiotics to livestock rations.

Solana strawberry: New variety yields fruit of high quality in southern California trial plantings
by R. S. Bringhurst, Victor Voth
| Full text HTML  | PDF  
A new strawberry variety—the Solana—is released by the University of California for unrestricted propagation. California nurserymen were supplied a few plants in 1957 to establish foundation stock. Plants should be generally available by December 1958. The University of California does not have plants for distribution.
