SUMMARY Under severe infestation pressure and delayed emergence following mid‐October drilling, only dieldrin seed dressing gave an acceptable control of wheat bulb fly, Leptohylemyia coarctata (Fall.). The control afforded by commercial seed dressings of BHC, carbopheno‐thion, chlorfenvinphos, ethion and the experimental compounds GS 13006 and pirimiphos‐ethyl, and by chlorfenvinphos granules was markedly inferior to that obtained with dieldrin seed dressing. In short‐row screening trials, bendiocarb, C 10015, C 18244, carbo‐furan, dialifor, ethoprop, iodofenphos, methiocarb, ‘Phosvel’, PPC‐3, propoxur and RD 21192 showed little promise. Phoxim and pirimiphos‐ethyl showed some promise but were not sufficiently active to warrant further study. Special seed dressing formulations of ‘Dursban’ did not overcome the inherent phytotoxicity of the compound to germinating wheat seed.
