Orchard sprinkler irrigation: Studies show supply of readily available soil moisture more important for fruit growth than type of irrigation
by A. H. Hendrickson, F. J. Veihmeyer
| Full text HTML  | PDF  
Not available – first paragraph follows: Sprinkler irrigation has many advantages in deciduous orchards, but also presents problems not found with surface irrigation.

Alfalfa hay quality: Leaf shatter loss greatest when hay is handled at low moisture content
by John B. Dobie, Luther O. Jones, F. P. Zscheile
| Full text HTML  | PDF  
Not available – first paragraph follows: Raking alfalfa hay at the wrong time increases leaf shatter—loss of leaves— and may reduce yield by 20% to 30% which means $8.00 to $12.00 of every $40.00 worth of hay may be left in the field.

DDT resistant leafhoppers: Malathon outstanding for grape leafhopper control in tests in areas where DDT resistance was present
by E. M. Stafford, Fred L. Jensen
| Full text HTML  | PDF  
Not available – first paragraph follows: Field tests and experiences of many Tulare County grape growers in 1952 showed that a 4% malathon dust gave excellent kill of leafhopper adults and nymphs—in both spring and summer treatments.

Acaricides on apples and pears: Tentative ratings of II acaricides given for spider mite control in northern California for 1953 season
by Arthur D. Borden, Harold Madsen
| Full text HTML  | PDF  
Not available – first paragraph follows: Season to season variance in the effectiveness of new chemicals—used as acaricides for spider mite control on apples and pears in northern California—makes it necessary that only tentative toxicity ratings of the acaricides be listed following each season's field investigations.

Cyclamen mite on strawberry: Successful control by use of natural enemy of pest possible as indicated by results of field investigations
by C. B. Huffaker, C. E. Kennett
| Full text HTML  | PDF  
Not available – first paragraph follows: The predatory mite—Typhlodromus reticulatus or T. cucumeris—which feeds on the cyclamen mite brought and held the pest under fairly good control in strawberry fields during tests in 1952.

Nematode on cotton: Root-knot nematode control by soil fumigation profitable in Kern County
by D. J. Raski, M. W. Allen, V. E. Burton
| Full text HTML  | PDF  
Not available – first paragraph follows: Soil fumigation enables a grower to plant' cotton on land infested with root-knot nematode, Meloidogyne incognita var. acrita,—and to obtain yields that give profit above cost of fumigation.

Pests of red kidney beans: Increased yields resulted from proper timing and application of control treatments tested in 1952 trials
by Harry. W Lange, Elmer C. Carlson, Ronald S. Baskett
| Full text HTML  | PDF  
Not available – first paragraph follows: Control of the two-spotted mite and the valley leaf miner—by a single application of an insecticide-acaracide combination—increased yields of red kidney beans in experiments conducted at Linden in 1952.
