Comparative control of pineapple postharvest Thielaviopsis fruit rot caused by Thielaviopsis paradoxa with guazatine (panoctine 40) and benomyl was studied. The experimental fruits were first artificially inoculated with the pathogen then dipped into fungicide suspensions prior to packaging and storing in a cold room operated to simulate pineapple fresh fruit shipment from the Philippines to Japan. Data of 2 trials showed that disease control based on percent disease rating and disease severity index, with 3000 ppm a.i. guazatine was comparable or better than that of the standard commercial postharvest treatment of 2000 ppm a.i. benomyl after 16 days cold storage of the fruits at 12-13 C/90 RH or at this condition plus 5 days storage at 28-30 deg C
