Brucellosis in dairy cattle: Whey test accurately detects infected cows and distinguishes between reactions to late vaccination and virulent infection
by H. S. Cameron
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Vaccinating calves against brucellosis reduces the incidence of the disease but can not be expected to eradicate infection.

Variation in milk constituents: Small variations in milk composition may require processing modifications or result in products of inferior market quality
by T. A. Nickerson, N. L. Hubbert, C. I. Campbell
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The composition of milk changes during a year due to stage of lactation of the cows primarily, and to feed and weather conditions and those changes may cause difficulties in dairy product manufacture.

Rhizopus rot on peaches: Ammonia gas fumigation immediately following harvest may provide effective control of disease causing serious losses
by I. L. Eaks, J. W. Eckert, C. N. Rolstacher
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: It is probable that effective control of Rhizopus rot—Rhizopus nigricans Ehr.—on peaches can be obtained—without fruit injury—by two 6-hour fumigations of an average ammonia concentration of about 250 ppm—parts per million.

Machine to disbud rootstocks: Adapted electric bench grinder facilitates disbudding grape cuttings before planting and avoids later growth of suckers
by C. J. Alley
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Thorough disbudding—removal of all unwanted buds, or eyes—of a root-stock cutting before rooting it in the nursery costs far less in both money and time than removing suckers after the vine has been planted in the vineyard.

Control of solar radiation: Housing comfort in both summer and winter can be improved by construction designed to take advantage of solar angles
by L. W. Neubauer

Summary Not Available – First paragraph follows: Shade—cast by roof overhangs, projections, louvers, trees—can be used to control the sun's heat in residences, machine sheds and livestock buildings or enclosures.

Potash fertilizer on potatoes: Yields of field-run White Rose potatoes increased materially by potash treatments in fertilizer trials in Madera County
by Clarence E. Johnson
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Out of 11 trials completed over a nine-year period, significant responses—increases as high as 31%—have been obtained from five out of six trials on Ripperdan soils. In the sixth trial on Ripperdan soil and in one trial out of three on Hanford soils, the response was only slightly below the degree of significance. No response was obtained in one trial each on a Ripperdan-Dinuba soil and on a Grangeville soil.

Hooded atlas barley: Studies indicate development of hooded barley competitive with awned doubtful
by Coit A. Suneson, Burt J. Hoyle
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Dual-purpose — hay and grain — Hooded Atlas barley was created from a lineage of about 5,000 plants grown during an 18-year period.

Strawberry leaf miner damage: Effectiveness of natural enemies usually holds pest damage below levels of economic importance in commercial plantings
by Leslie M. Smith, William W. Allen, W. Harry Lange
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: The larvae of a small, leaf-mining moth—Tischeria sp. Family Tischeriidae—apparently a new species close to T. aenea Frey and Boll, burrow serpentine mines in the leaves of strawberry plants.

Citrus mite control: Effective new acaricide of low toxicity to insects registered for use on citrus
by L. R. Jeppson
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Relatively safe to handle during spray operations and less toxic to mammals than DDT, Kelthane—4,4′-dichloro-a-(trichloromethyl) benzhydrol—has utility for control of mites injurious to citrus in California.

Gibberellin on zoysia grasses: Plant growth regulator did not improve establishment of slow growing turf grass in either greenhouse or field experiments
by Victor B. Youngner
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Gibberellic acid—one of several similar growth promoting substances—produces a rapid abnormal elongation of shoots and leaves in many plants at dilutions as low as one ppm—part per million.
