Abstract

Improper timing—or complete omission—of DDT treatment was the major contributing factor to the relatively high infestations of codling moth in walnuts in some areas of southern California during the 1954 season.

Time study of plum packaging: Comparative study of labor requirements in packing plums in wooden crate and in experimental carton in test shipments

Costs of lumber production: Production costs in California have become vital factor in determining nation-wide use of lumber and its price level

Range cover after noxious weed: Desirable and undesirable grasses and forbs compete for range space cleared of Klamath weed by leaf-feeding beetles

Brush control with chemicals: Hormone-type sprays tested for use in brushland management prove most effective when applied to current year seedlings

Petal blight disease of azaleas: Control of fungus-caused disease of azaleas and closely related plants is essential to prevent its further spread

Disease-free geranium stock: Production of healthy cutting stock increased by growing system that permits higher returns from smaller acreage

Valencia orange size and 2,4-D: Adequate soil moisture important for increasing fruit sizes with 2,4-D sprays applied when fruits are 4–12 weeks old

Argentine ant control on citrus: Granular formulations of certain chlorinated hydrocarbons applied to soil surface show promise in preliminary trials

Orange fruit size and yield: 31-year study of interrelationship of temperatures and orange fruit size and yield indicates influence of some climatic factor
