The information in this pamphlet is based on the results of the cooperative tests in South Dakota and from summarized results of tests in other areas. Experiments have been conducted during the past year by the South Dakota Agricultural Experiment Station cooperating with the United States Department of Agriculture. Twenty experimental plots were established to learn how effective the 2, 4-D sprays are as weed killers. 2, 4-D was tested in comparison with the proven chemical weed killers, sodium chlorate, Atlacide and borax. Creeping jenny, leafy spurge, perennial sow thistle, Canada thistle, and other weeds were included in the tests.
