Aphid parasites established: Natural enemies of spotted alfalfa aphid brought from Middle East expected to be established throughout the state in 1958
by Kenneth S. Hagen, James K. Holloway, F. E. Skinner, G. L. Finney

Summary Not Available – First paragraph follows: Three imported species of wasps—Praon palitans Muesebeck, Trioxys utilis Muesebeck and Aphelinus semiflavus Howard—parasites of the spotted alfalfa aphid, are abundant in southern California and are becoming established in northern California.

Gibberellin on white potatoes: Applied to freshly harvested, resting potato tubers, or used in preharvest foliar sprays, gibberellin promotes sprouting
by Lawrence Rappaport, Herman Timm, Laverne F. Lippert
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Year-round production of potatoes in California frequently necessitates the use of resting tubers as planting stock. However, resting tubers normally do not sprout for 1-4 months after harvest—depending on varietal characteristics—despite exposure to optimal environmental conditions.

Chemicals on European red mite: Two different methods of evaluation of spray materials for spider mite control used in field tests during 1957 season
by Harold F. Madsen
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Variable conditions in the fruit growing areas of California make it difficult to project the results from evaluation tests in one area to another. As a consequence, field plots were established for the 1957 season in Bartlett pear orchards—in Sacramento, Solano, El Dorado, Lake, and Mendocino counties—for University personnel to evaluate spray materials under local conditions. As a correlative evaluation, spray chemicals used in codling moth and aphid control plots were checked for their effects on spider mites.

Crown mite damage on spinach: Investigations demonstrate value of early chemical treatment for control of relatively new mite affecting spinach leaves
by W. H. Lange, O. G. Bacon
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Damage to spinach by the crown mite—Tyrophagus dimidiatus (Hermann) — was first observed to be of economic importance during the spring of 1949 in the Santa Clara Valley. Since that outbreak the mite has caused periodic damage to fall and spring planted spinach in most areas, but is more destructive in the coastal growing regions.

Fertilizer trial with plums: Results of tests with Santa Rosa variety in principal plum growing area of Kern County determined by leaf analyses
by E. L. Proebsting, A. N. Kasimafis
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Two sets of experimental plots in 15-year old Santa Rosa plum orchards—on Marianna rootstock—were laid out north of Arvin in 1951. Orchard A had 75 trees per acre and was on Foster loam. Orchard B had 90 trees per acre on Hesperia fine sandy loam.

Manzanita control in ponderosa: Prescribed burning used to kill brush and to deplete seed source in the soil and promote germination of pine seedlings
by H. H. Biswell, A. M. Schultz
| Full text HTML  | PDF  
Summary Not Available – First paragraph follows: Prescribed burning has been used successfully to manipulate brush in second-growth ponderosa pine to increase desirable plants; to kill mature brush plants; to kill brush seedlings and deplete the amount of seeds in the soil; and, at the same time, to prepare a better seedbed for pine seedling germination.
