Abstract

Control of the codling moth on susceptible varieties of walnuts usually requires spray applications each year.

Also in this issue:

Fruits and vegetables: State in top rank because of advances in farm methods, technology, marketing, merchandising, and food science

Chemical control of brush: Field experiments in eradication of range brush by chemical treatment promising but more work needed

New fruit varieties: Produced by superior seedlings, chance hybridization or planned by selective breeding programs

Cereal breeding: Investigations show awned wheat exceeds awnless in yield, kernel weight and test weight per bushel

Brown almond mites: Overwintering eggs appear in June with three life cycles a year offering an advantage in control program

Stump grafting old citrus: Familiar bark grafting practice commonl proves adaptable to old orange trees in used on walnuts San Bernardino County

Downy mildew control: New chemicals greatly reduce damage from downy mildews of leafy garden vegetables

Spread of apricot roots: Unirrigated trees apparently obtained moisture from adjacent irrigated plot in experimental orchard at Winters

California sugar beet research: Data obtained by scientists and applied by growers effectively increased production efficiency and yield

Factors which modify the resistance of wheat to bunt, Tilletia tritici
