Soil fumigation with Telone® (mixed dichloropropenes), DD® Mixture (dichloropropanc-dichloropropene mixture), and ethylene dibromide, applied at 20 gal, 25 gal, and 36 lb/acre, respectively. and broadcast applications of granulated diazinon, parathion, and phorate, applied at 2, 4, and 11Ill/acre, respectively, gave economic control of the Pacific Coast wireworm (Limonius canus LeConte) on potatoes in sandy loam soil. Cullage was reduced 93.6- 100%. Granulated disulfoton. broadcast at 3 Ib/acre, gave significantly less control than other broadcast treatments. Post-planting side dressings of granulated parathion, phorate, Stauffer N-2790 (O-ethyl S-phenyl ethylphosphonodithioate), and Bayer 25141 [O-O-diethyl O-p- (methylsulrll1yl)phenyl phosphorothioate), applied at 3 lb/acre, reduced cullage 74.4-85.2%. Granulated disulfoton and Bayer 37289 (O-ethyl 0-2,4,5-trichlorophenyl ethylphosphonothioate) at 3 Ib and naphthalene crystals at 450 lb/ acre were significantly inferior to the other sidedress treatments. Phorate and disulfoton granules gave as good control when metered onto the soil surface in bands 6 in, wide in the furrow left by the press-wheel potato planter as when side dressed in the soil at the same rate. Of all diazinon, disulfoton, parathion, and phorate treatments, only phorate applied in the planter press-wheel furrow left a detectable residue above the tolerance in tubers collected 3 weeks before harvest.
