HPIPM:Potato Storage Disenfecting

Author: Gary D. Franc

Potato pathogens may survive on surfaces contacted during storage. Careful cleaning and disinfestations of potato storage and handling equipment can prevent the spread of Bacterial Ring Rot and other diseases. Cleaning and disinfesting surfaces is especially critical for storage of the seed potato crop.

Effective sanitation starts with a thorough cleaning of all surfaces before application of the disinfectant. If not properly cleaned, soil, clay and organic material may render the disinfectant les effective. Most disinfectants require that treated surfaces remain wet for up to ten minutes for full activity. Addition o f a wetting agent to the spray solution may aid in achieving coverage and penetration. The solution should be changed frequently to avoid neutralization. Products containing chlorine-dioxide are in the process of registration, and may be available shortly.
