Abstract

A tiny wasp, the clover seed chalcid– Bruchophagus gibbus (Boh.)–is of increasing importance as a major pest in central California alfalfa seed producing areas. The insect has long been known in California and its damage has been particularly severe in the southern desert regions.

Frozen strawberry competition California's: Slight interregional advantage could be reduced by small changes in the cost structures in competing regions

Gibberellin sprays on celery: Field trials in southern California revealed differences in results due to spray concentrations, timing, and to season

Alfalfa hay conditioning tests: Relative drying rates, field losses, chemical composition of the hay, and feeding response of sheep studied in '58 season

Brown spot of bartlett pears: Disorder of canning pears a direct result of impact bruising of firm fruit during the handling operations after harvest

Mechanical potato harvesting: Studies conducted in Kern County indicated less injury to potatoes when harvested by machine than by hand harvesting

Nitrification of fertilizers: Mean winter temperature of 45°F prevalent in state's farm areas not sufficiently low to prevent substantial oxidation

Area-wide drainage: Herringbone pattern and interception type systems solve drainage problems

Integrated control measures: Experiments in lemon grove near Carpinteria showed selective miticides to be compatible with biological control of red scale

Filbertworm control: Experimental insecticides show promise in tests on northern California walnuts

Application of prior research: Accumulated information obtained by research often provides ready solutions to many problems of agricultural production
