Abstract

Five unidentified species of parasitic entomophthorous fungi are now known to be attacking the spotted alfalfa aphid—Therioaphis maculata (Buckton)—in California.

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

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

Codling moth infestations up: Damage to harvested walnuts increased markedly in northern California during the 1956 season in comparison with 1955

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
