Duplicate experiments were carried out on bulk sorghum stored in South Queensland and in central Queensland. Bioassays of treated grain, conducted during 6 months' storage, established that fenitrothion at 12 mg/kg + bioresmethrin at 1 mg/kg and pirimiphos-methyl at 4 mg/kg + carbaryl at 8 mg/kg controlled typical malathion-resistant strains of Sitophilus oryzae (L.), Rhyzopertha dominica (F.), Tribolium castaneum (Hbst.) and Ephestia cautella (Wlk.). Chlorpyrifos-methyl at 10 mg/kg + pyrethrins at 1.5 mg/kg + piperonyl butoxide at 12 mg/kg and fenitrothion at 12 mg/kg + (1R)-phenothrin at 1 mg/kg also controlled all the tested species except E. cautella. Chemical assays established that the residues and rates of breakdown of these grain protectants on sorghum conformed to the general pattern for other cereal grains; residues from the above treatments were below the individual maximum residue limits recommended by the Codex Alimentarius Commission
