Insecticidal seed treatments on baby lima beans effected a 45% mortality of the eastern field wireworm, Limonius agonus (Say), found in a row 18 days after planting. Average gains of (61.6% in stand and 36.4% in whole plant weight were attributed to seed treatments, as measured at harvesttime. No advantage was found in using lindane, dieldrin, heptachlor or aldrin at more than 0.5 oz. per 100 pounds of seed. Averages from three separate corn experiments in loam soil infested with wireworms (Agriotes mancus (Say) and Melanotus sp.), showed 5.8% increase in stand and a .5.7% increase in yield using 0.1 and 0.25 oz. of heptachlor. dieldrin, or aldrin per bushel of seed. These gains were 52.7 and 25.7%. respectively, of the benefits derived from "maximum control" plots where 1.5 pounds of heptachlor per acre were employed as a soil treatment. There was no significant difference between the three insecticides or between the two dosages employed.
