Grape bud mite injury: Effect of pruning date on incidence of injury investigated near Cucamonga in 1949–50 season
by M. M. Barnes , A. A. McCornack
pp5, doi#10.3733/ca.v005n01p5
Abstract
Not available – first paragraph follows: Spraying trials have been conducted in southern California over a period of three years concerning control of the grape bud mite, a physiological strain of the grape erineum mite–Eriophyes vitis– (Pgst.). During this period approximately 55 acres of plots have failed to provide information concerning the prevention by spraying of the injury caused by this mite. This is because of the erratic nature of the appearance of bud mite symptoms.

Broad bean weevil: Control of pest may restore the once important fava bean crop
by Woodrow W. Middlekauff , R. H. Sciaroni
pp7-13, doi#10.3733/ca.v005n01p7

Range grass and reseeding experiments in California: Complexity of range improvement problem requires long-term research program involving allied fields of study
by R. Merton Love
pp8-10, doi#10.3733/ca.v005n01p8
Abstract
Not available – first paragraph follows: More than 2,900 accessions of forage plants–including grasses, legumes, and forbs–have been tested at Davis and at Berkeley in a long-term research program. In 1950, 90 species and varieties were planted which have never before been tried in California. These included 40 strains of subterranean clover.

Diseases of the loganberry: Susceptible to several virus and fungus diseases Logan is immune to Verticillium wilt and powdery mildew
by Stephen Wilhelm , H. Earl Thomas , Edward C. Koch
pp11-14, doi#10.3733/ca.v005n01p11
Abstract
Not available – first paragraph follows: Greenhouse and field tests carried on for four years have shown that the Loganberry is not affected by Verticillium wilt, the most serious disease of the Boysen and Young varieties. The Logan therefore can be grown on land cropped previously to tomatoes, potatoes or other susceptible crops without danger of wilt losses, and can even be intercropped the first year with tomatoes. The Loganberry is also immune to powdery mildew, a serious disease of the Boysen and Young varieties in the coastal berry growing districts of California.
