Inbreeding: Investigations with dairy cattle indicate inbreeding can lead to desirable or undesirable results
by W. C. Rollins
| Full text HTML  | PDF  
Not available – first paragraph follows: Inbreeding can lead to increased uniformity within the inbred stock, increased prepotency in outcrosses, production of abnormal types, and symptoms of decline in vigor.

Spray residues: On apricots after codling moth sprays, 1950 recommendations
by Arthur D. Borden, Harold Madsen, Stanley Benedict
| Full text HTML  | PDF  
Not available – first paragraph follows: The problem of spray residues on apricots has received considerable attention the past two seasons largely due to the necessity of applying control measures for codling moth. Without this control the grower and processor are confronted with heavy losses due to wormy fruit and if sprays are applied, there will be minimum amounts of the spray chemical in canned or dried fruit.

Mite populations on grapes: Effect of sulfur dust treatments on predatory mites and red spider mite
by Leslie M. Smith
| Full text HTML  | PDF  
Not available – first paragraph follows: The annual rise and fall of populations of the Pacific mite—Tetranychus pacificus McG—and the Willamette mite— Tetranychus willamettei McG—on grapes has puzzled growers and entomologists for years. In the fall of 1949 the last explanatory link was supplied.

Nitrogen fertilizer: California deciduous fruit orchards respond in variety of ways due to individual conditions
by E. L. Proebsting
| Full text HTML  | PDF  
Not available – first paragraph follows: Nitrogen is the only fertilizer applied to a substantial acreage of deciduous fruit orchards in California. Usually the first limiting nutrient in the production of those orchards is nitrogen. Only a part of the total deciduous acreage has reached a level where response to nitrogen fertilizer is obtained.

Wind borne pest: Omnivorous leaf tier controlled readily by insecticide treatments
by A. Earl Pritchard, W. W. Middlekauff
| Full text HTML  | PDF  
Not available – first paragraph follows: Satisfactory control of the omnivorous leaf tier—Cnephasia longana—can be obtained with either DDT or dichlorodiphenyl dichlorethane when used at a rate of two pounds of the 50% wettable powder per 100 gallons of water.
