Abstract

For the first time, a practical and economical means of controlling the European lettuce root aphid—Pemphigus bursarius (L.)—seems to be available for commercial use.

Also in this issue:

Frozen strawberries: Study indicates efficiency of mechanical crate dumping in most processing plants

Strawberry fertilizer trial: Tests in new strawberry planting on old potassium deficient apricot land indicated no response to potash or phosphate

Cantaloupe crown blight study: Observations reveal disease to be severe on all commercial varieties of spring harvested cantaloupes in desert regions

Gibberellin on flower crops: Studies made of response of some commercially grown flowers to applications of plant growth regulating chemical compound

Walnut aphid control: Comparative study of control treatments made during heavy infestations in 1956

Rooting cuttings under mist: Leafy softwood cuttings of paradox walnut hybrids rooted successfully in mist propagation tests during summer of 1956

Improved pastures: Both sheep production and forage yield increased by range improvement

Swine feeding tests: Supplemented cooked garbage tested in feeding trials in Los Angeles County

The development of resistance to hydrocyanic acid in certain scale insects
