All machinery, transport and storage surfaces that the seed will contact should be cleaned and disinfected
prior to receiving new seed. Sanitation consists of cleaning and disinfecting all equipment, storage, tools
and pallet boxes that contact the seed potatoes. Since most disinfectants are inactivated by soil and plant
debris, it is essential that this material be removed by thoroughly cleaning the equipment and storage with a
pressure washer or steam cleaner before the disinfectant is applied. The seed storage and all equipment
coming in contact with the seed lot should be disinfected with a quaternary ammonium compound such as
Ag-Services Incorporated General Storage Disinfectant, Bardak 2210 Disinfectant Sanitizer, or DMR-23
Disinfectant. Surfaces must remain wet for at least 10 minutes for the disinfectant to destroy disease
organisms.
