Part IV of a series of reports of studies on the effects of packinghouse equipment, plant layout, and work methods on efficiency and costs. These studies have been made co-operatively by the University of California Giannini Foundation of Agricultural Economics, and the Bureau of Agricultural Economics, United States Department of Agriculture, under the authority of the Research and Marketing Act. Detailed reports are available by addressing the Giannini Foundation, 207 Giannini Hall, University of California, Berkeley 4.

Producers of chicken fryers in the Hayward area of Alameda County have a wide range of outlets through which their fryers can reach consumers.

Two of the newer chemicals show outstanding possibilities for the commercial grower's use to control mites injurious to citrus in California.

Nor does their application effectively reduce populations of injurious insects.

Dieldrin has shown outstanding promise in the control of citrus thrips on oranges, grapefruit, and lemons during three years of experiments.
