Disease and sprout control in individually film wrapped potatoes.

Potatoes (cv. Russet Burbank) were individually wrapped in Cryovac D-955, a biaxially oriented shrink film, and stored at 24 deg C. The wrapped potatoes were either treated with a fungicide (thiabendazole), or the film itself was coated with an antimicrobial agent (silicon quaternary ammonium salt) to control diseases that may appear during storage and marketing. Under film-wrapped conditions, disease control using a fungicide or antimicrobial agent was not completely successful; however, the marketable qualities of the potatoes were not affected. Disease spread under film-wrapped conditions was minimized if the potatoes were disinfected in chlorine (0.5% sodium hypochlorite) and wrapped after they were dried. In another study dormant and post-dormant potatoes were individually film-wrapped after they were treated with maleic hydrazide (MH) (pre-harvest treatment) or isopropyl N-(3-chlorophenyl) carbamate (CIPC, chlorpropham) (postharvest treatment) for sprout control. Under film-wrapped conditions, MH decreased sprouting in the dormant potatoes but not in the post-dormant potatoes. CIPC inhibited sprouting in the post-dormant film-wrapped potatoes but was less effective in the dormant potatoes.
