Vapor-Heat against fruit fly: Variable factors affect injury to citrus and avocados in sterilization tests for control of fruit fly insects
by Walton B. Sinclair, D. L. Lindgren
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: Eggs and larvae of fruit flies are destroyed by vapor-heat sterilization but the treated fruit may be injured. The kind and amount of injury depend on the tolerance of the fruit to saturated atmospheres at llOF and 120F for specified lengths of time.

Use of iron chelates: Supplying plants with iron through soil treatment limited to high-value plantings
by O. R. Lunt, A. Wallace
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: Use of chelating agents—especially the new compound Fe 138—to correct iron chlorosis by effectively supplying iron to plants has proved promising in a series of experiments.

Lightweight catching frames: Effect on fruit quality and harvesting costs studied in successful field trials with Imperial and French prunes
by A. A. McKillop, R. L. Perry, A. Shultis
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: A lightweight catching frame helps protect fruit quality from harvest damage because—by keeping the fruit off the ground—it minimizes skin damage and imbedded dirt.

Cyclamen mite investigations: Control of cyclamen mite on ornamentals may be possible with spray treatments of endrin, azobenzene, and isodrin
by William W. Allen
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: The cyclamen mite—Tarsonemus pallidus—is a dreaded pest to both the strawberry grower and the nurseryman.

The Egyptian alfalfa weevil: Pest established in localized areas in southern California closely related to alfalfa weevil in northern part of state
by H. T. Reynolds, L. D. Anderson, A. S. Deal
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: The Egyptian alfalfa weevil—Hypera brunneipennis (Boh.)—is causing economic losses in localized areas in Imperial and San Diego counties. Because it is damaging to crops in hot dry areas as well as in relatively cool, coastal localities, this pest poses a threat to all the alfalfa-and clover-producing districts in the state.

Studies on sulfur in alfalfa: Sulfur content of alfalfa grown on a low-sulfur soil more than doubled by application of gypsum in tests near Delhi
by V. V. Rendig, W. C. Weir, T. S. Inouye
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: Alfalfa protein is relatively low in the sulfur-containing amino acids, and the alfalfa's nutritive value may thereby be limited. This has been indicated at several laboratories in biological assays—feeding tests with small animals. Increasing the sulfur content of alfalfa, therefore, may improve its value as a feed.

Tentiform leaf miner on pears: Codling moth and spider mites affected by treatments in leaf miner control studies in Bartlett pear orchard near Penryn
by Harold F. Madsen, James E. DeTar
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: Approach to the problem of tentiform leaf miner control was changed during the 1954 season—from that of previous seasons—in the continuing studies in the Auburn area.

New acaricide for citrus mites: Chlorobenzilate formulations have low toxicity to warm-blooded animals but in tests gave effective control of mites on citrus
by L. R. Jeppson
| Full text HTML  | PDF  
Abstract Not Available – First paragraph follows: Chlorobenzilate—ethyl p, p'-dichlorobenzilate—offers certain advantages in citrus pest control: it has a very low toxicity to warm-blooded animals which places it in the same category as Ovotran and Aramite; its application does not seriously affect insect parasites and predators or bees.
