Experiments were undertaken to evaluate the effect of insecticides from selected chemical groups on growth and patulin production by P. urticae at a concentration of 1, 10 and 100 mg/liter(ppm). The organophosphate insecticides Naled and Dichlorvos inhibited patulin production by 100 and 89%, respectively, at the 100 mg/liter concentration. Variable inhibitory activities were ascribed to the organophosphate insecticides Malathion and Diazinon® which inhibited patulin production by O‐52% at the 100 mg/liter concentration. The carbamate insecticides Landrin® and Sevin® inhibited patulin production by 85 and 100% and completely inhibited sporulation at the 100 mg/liter concentration; however, they did not inhibit growth of P. urticae significantly. Inhibition of growth and sporulation by other insecticides varied and was not significant at the 1 and 10 mg/liter concentration.
