“…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.

“…Although radish has been frequently used as a test crop in studies on control of the cabbage maggot (2,3,8,14), most of the experiments were not designed to develop practical recommendations for protection of this crop and no data were given on insecticide residues. This is a report on the effectiveness of broadcast treatments of granular aldrin, heptachlor, and chlordane for control of the cabbage maggot in radish and on the insecticide residues resulting from their use.…”

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.

CEREAL seed dressings intended for wireworm control do not always prevent serious damage by wheat bulb fly, Leptohylemyia coarctata Fall., when used at the conventional rate of 2 oz. per bushel of seed (equivalent to 0 • 08-0 • 04 per cent active ingredient to weight of seed) (Gough, 1953). Work was started to see if a better method of applying insecticide could be devised. The following materials and methods were tested during the period 1953-58: SEED TREATMENTS. ^fl/Mma-BHC and dieldrin, formulated with talc, were used as dry dusts to dress the seed in the usual manner, but at higher rates than normal. In field trials an aqueous solution of methyl cellulose was used as a sticker for dieldrin, aldrin and heptachlor (heptachloro^, 7-methano tetrahydroindene).COMBINE-DRILLING WITH THE SEED. In a preliminary experiment gamma-BHC, dieldrin and demeton were formulated with gypsum dust. For field tests dieldrin and aldrin were formulated with an inert siliceous filter to give a fine dust (mean particle size 9fi). A granular formulation of dieldrin consisted of the insecticide coated on l-inch mesh brick chips.BROADCAST TREATMENTS. For these, the siliceous earth formulation of dieldrin was broadcast along the rows by hand. SPRAYS AND DRENCHES. In a smaU-scale trial, parathion and demeton were watered directly on to the platits, or applied with a small pairit spray. In other trials, parathion, thimet (diethyl ethylthiomethyl dithiophosphate) and dipterex (dimethyl trichlorohydroxyethyl phosphonate) were applied with a spray boom carried by hand. The wetter used for dipterex, and for parathion in tables lb and 2, was agral LN, consisting of ethylene oxide condensates with substituted phenols or fatty alcohols. Atlox 3335 was used in subsequent experiments. This is alkyl aryl sulphonate blended with polyoxyethylene sorbitan esters of mixed fatty and resin acids.
