Abstract

There is little doubt that the insecticides parathion, malathion, and TEPP prevented a widespread devastation of California's alfalfa industry following the 1954 appearance of the spotted alfalfa aphid—Therioaphis maculata (Buckton) but the materials also proved to be toxic to insect enemies of the aphid.

The toxic effect of certain chemical solutions on spores of Penicillium italicum and P. digitatum

Problems of water districts: Economic merit and feasibility are important considerations in justifying the construction of proposed district projects

Rosy apple aphid control tests: Dormant oil plus phosphate compounds applied to control the overwintering eggs more efficient than spring foliage sprays

Plastic shelters for new lambs: Protection from weather during first few days after birth reduced losses in tests during January-March lambing season

Nitrogen-fixation by deerbrush: Greenhouse experiments suggest deerbrush has root nodules like leguminous plants with nitrogen-fixing properties

Aureomycin in livestock feed: Antibiotic in form of a prepared alfalfa-base pellet added to ration in feeding trials with weaner calves and yearlings

Solana strawberry: New variety yields fruit of high quality in southern California trial plantings

Retail grocery store services: Types of telephone ordering and of delivery services offered customers shown to be influenced by characteristics of store
