“…brassicae in Canada and the United States (2, 3, 4, 9, 10,11,13,14), and by mixed populations of H. bra:ssicde and H. floralis in Canada (8). They have been moderately effective in reducing damage to crucifers by H'floralis in Japan (7) but less effective in Sweden and Denmark (5,6)' The effectiveneis of these insecticides in destroying root maggots in crucifers has been repofted twice only (4,10).…”

Three spray treatments of heptachlor at 4 pounds, dieldrin at 4 pounds, or endrin at 2 pounds in 80 gallons of water per acre in a 12-inch band centered on the rutabaga row eliminated maggots of Hylemya floralis (Fall.) about the roots and prevented damage by the maggots, when applied at intervals of 10 or 11 days beginning within 2 or 3 days after the start of oviposition. Residues of dieldrin were below and those of endrin were above the legal tolerances in Canada. Residues of heptachlor (epoxide not determined) were below the legal tolerance. A single soil band treatment of heptachlor, dieldrin or aldrin dust at 5 pounds per acre, applied in a 12-inch band on the seeded rows and incorporated immediately into the top [Formula: see text] to 1 inch of soil, gave similar control, but insecticide residues in the rutabaga were not determined. None of the treatments was phytotoxic.

“…H. brassicae attacking the stem crucifers such as cabbage, cauliflower, Brussels sprouts, and broccoli is obtained with certain of the chlorinated hydrocarbon insecticides. These insecticides also give good control of the maggot in turnips and rutabagas in all but muck soils (6,10,11,15). However, insecticidal control of the maggot in radish has been mediocre.…”

In sandy loam soil at Ottawa, heptachlor and aldrin granules, broadcast at 3 lb. of toxicant per acre before planting, gave respectively 70 to 80 and 58 to 84 per cent control of a very severe infestation of the cabbage maggot in radish planted 0, 7, 15, and 21 days after treatment. Chlordane granules at 5 lb. gave 4 to 48 per cent control. The granulated insecticides were applied to the surface of the soil with a hand fertilizer spreader and raked into the top 2 inches. Insecticide residues on the radish roots at harvest were below the tolerances recently established in Canada for this crop.
