Experimental plantings of three cruciferous root crops, radish, turnip and rutabaga, indicated that heptachlor applied in various ways gave the most consistently good control of root maggots (Hylemya spp.). A comparison of different methods of application for maggot control in radish and turnip showed that the best materials gave the highest degree of maggot control as seed or furrow treatments to radish, and as furrow treatments to turnip. The efficiency of a number of insecticides for control was compared by furrow treatment to turnip. Heptachlor or aldrin at 1 pound actual toxicant per acre gave more effective control than any of the other materials used. Similarly, as broadcast treatments to rutabagas made before planting and mixed with the top 3 inches of the soil, heptachlor and aldrin at 2 pounds actual toxicant per acre were the most effective control agents.
