Abstract

Natural enemies—native insect predators and fungus diseases—helped to hold the spotted alfalfa aphid in check during the 1955 season. In some fields an epizootic—corresponding to an epidemic among humans—of a fungus disease prevented damage by the aphid.

Fluid milk price control: Dynamic industry provided with means of maintaining orderly relationships through mechanism of Bureau of Milk Control

Seed treatment of lima beans: Combination fungicide-insecticide seed treatments protect plants against soil-borne pests and permit increased yields

Growth regulators on beans: Studies in southern California indicate properly applied sprays may increase yields of dry limas under some conditions

Blackberry yields increased: Growth regulator sprays tested on Boysen, Olallie, and Thornless Logan varieties in San Diego County in 1955

Prune size affected by 2,4,5-T: Erratic response in fruit size obtained after experimental treatment of mature trees with sprays of growth regulator

Growth regulators on apricots: Tests with several regulators indicate 2,4,5-T is best for increasing size, hastening maturity, controlling fruit drop

Frosted scale on walnuts: Codling moth treatment, DDT drift from adjacent crops interfere with control of the pest by natural enemies

2,4-D Damage to young citrus: Young lemon, orange, and grapefruit trees may be severely damaged by direct application of, or by the drift of 2,4-D
