The potential for inhibition of citrinin production by P. citrinum NRRL 5927 was investigated using the pesticides naled, dichlorvos, malathion, pyrethrum, methoxychlor, mevinphos, ethion, diethyl toluene, allethrin, diazinon, trithion, guthion and atrazine. Citrinin was precipitated from culture media and quantitated by TLC and spectrophotometry at 640 nm. A TLC system consisting of precoated Silica‐Gel‐60 plates as the solid phase and ethanol‐ammonia‐H 2 0 (80:4:16) as the liquid phase separated citrinin more satisfactorily than other TLC systems previously reported. All pesticides except methoxychlor, atrazine, guthion, diethyl toluamide and trithion inhibited growth and/or citrinin production by >40% at the 100 μg/L concentration. Naled, dichlorvos, malathion, and diazinon inhibited growth and/or citrinin production >75% at concentrations of 100 μg/L.
