The use of 2,4-dichlorophenoxyacetic acid for weed control in hybrid seed corn crossing fields has not been recommended generally. The reluctance to use the herbicide in seed fields has been prompted by fear of damage to the valuable seed corn crop in the year in which the treatment is made, and the possibility of deleterious effects in seed produced on treated parental plants and in plants of the succeeding generation. A study was inaugurated at Ames, Iowa in 1947 to answer some of the questions regarding the effect of 2,4-D on seed corn production. Inbred lines of corn were used to obtain the desired genetic uniformity. The effects of an aqueous spray of the sodium salt of 2,4-D on the parent plants, seed yields, seed germination, and seedling vigor have been reported previously (1). The present report gives the results for the 1948 yield trial grown from single-crossed seed produced on inbred plants sprayed with 2,4-D in 1947.
