Gamma benzene hexachloride has been used successfully as a seed dressing in field trials for wireworm control. For application to cereals at 2 oz./bushel, the optimum concentration of γ‐isomer was 20–30 % in a dressing which advantageously included an organomercurial seed disinfectant. Risks to germination and plant growth were thoroughly explored in the field. The 20 and 30 % dressings were safe; over‐strength dressings containing 50 or 70 %γ‐B.H.C. did not reduce grain yields significantly. Seed dressed with 20 or 30 %γ‐B.H.C. germinated normally after storage for 12 months. When seed was dressed at 4 oz./bushel with 35 %γ‐B.H.C. and 1 % mercury as organomercurial, germination was delayed but total emergence was not affected.
