A potato flavor evaluation test was one phase of a coordinated investigation of the effects insecticides–absorbed by the soil–might have on plants, crops, and soils.

W. H. Ewart, Associate Entomologist, University of California, Riverside, directed the flavor evaluation tests with potatoes.

Paul Gerhardt, Assistant Entomologist, University of California, Riverside, co-operated in the experiments with the potato field plots.

Lloyd E. Vincent, Principal Laboratory Technician, University of California, Riverside, cooperated in most phases of the project.

The seed-corn maggot seed protectant experiments were conducted with the co-operation of J. C. Elmore, United States Department of Agriculture, Bureau of Entomology and Plant Quarantine, Whittier.
