Abstract

In the second year of tests, Guthion and Sevin–not yet released for use on walnuts–again showed encouraging control of the filbertworm on Payne and Franquette walnuts.

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

Clover seed chalcid in alfalfa: No effective chemical control measures yet available for use against insect causing heavy losses to alfalfa seed growers

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

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