These corn tests are a cooperative project between the Mississippi Experiment Station and the Division of Cereal Crops and Diseases, Bureau of Plant Industry, Soils and Agricultural Engineering, and the Division of Cereal and Forage Insect Investigations, Bureau of Entomology and Plant Quaran- tine, Agricultural Research Administration, U. S. Department of Agriculture.
