Abstract
Postharvest treatments with thiabendazole (TBZ) and benomyl reduced the incidence of chilling injury (Cl) in grapefruit (Citrus paradisi, MacFadyen) as expressed by peel pitting. The effect persisted during prolonged storage at 2, 5 and 8°C. Thiabendazole was more effective than benomyl. The effectiveness of both TBZ and benomyl in water suspension increased when followed by waxing, but the greatest reduction in Cl was obtained with the chemicals incorporated in the wax coating. The effect of TBZ was enhanced by increasing concentration and residues, while the effect of benomyl did not change with concentration. Both chemicals were effective in reducing rots during cold storage. There was a marked increase in the incidence of rots during shelf-life. These rots, primarily of the mold type—Penicillium digitatum Sacc. and P. italicum Wehmer, developed mostly in pits induced by the low storage temperatures.
