Abstract

Codling moth populations on walnuts vary from year to year but during the 1956 season—in all districts where investigations were conducted—there was a general rise in the seriousness of infestations.

Agricultural-business outlook: Farmers must understand and apply economic principles to the business of modern agricultural production by scientific means

Peach tree borer control tests: Fall treatments with soil fumigants and use of trunk sprays evaluated in experimental program during the 1955–56 seasons

Aphid resistance to parathion: Nonphosphate insecticides under study for control of spotted alfalfa aphid where pest develops resstance to parathion

Fungi on spotted alfalfa aphid: Spread of fungi by natural and artificial means is resulting in excellent biological control of aphid in many counties

Soil fumigation for nematodes: Nematocides tested for the control of root-knot nematodes affecting fresh market and canning tomato crops in California

California scaly bark disease of citrus: No known cure for infected trees but treatment in early stages of disease can retard its advance into successive stages with their increasing economic loss

Bartlett pears for canning: Ripeness of fruit at time of processing affects color, flavor, aroma, and over-all quality of finished product

Citrus weed control by monuron: Experiments with urea herbicides for weed control in citrus orchards encouraging but use of the chemicals is restricted

Weed control near grass areas: Soil fumigants and contact spray materials included in series of studies on control of weeds in relatively confined areas
