2016 Disinfectants for Potato Handling and Storage Equipment	
Type	Active ingredient	Products	Comments	
Chlorine generating products	
Note: Chlorine has significant human inhalation problems-follow safety precautions!	

Bleach	
Sodium hypochlorite	Many products available. Rate will depend on
product. Concentrations will vary from 3.25- 12%	Strong oxidizer (corrosive), rapidly inactivated by soil or organic matter, no residual activity. Water pH must be
4-8.	

Calcium hypochlorite	

Calcium hypochlorite	
Many products available. Rate will depend on product label.	Strong oxidizer (corrosive), rapidly inactivated by soil or  organic matter, no residual activity. Water pH must be
4-8. Can be applied directly to potatoes.	

Chlorine dioxide	
Chlorine dioxide	Oxine Sanitizer, SNiPER, EnviroCON, Clorodisys, CDG Solution 3000, and
Purogene	
Less corrosive than bleach, no residual activity, water pH not as critical.	
Non-chlorine generating products	

Quaternary Ammonium products	Quaternary Ammonium, benzalkkonium chloride, n-alkyl dimethyl benzyl ammonium chloride, N,N,-didecyl-N,N-
dimethyl ammonium chloride, etc.	
De-Bae, Virex, Roccal-D, AFBC, Breakthru, Micro Q64, Micro Ql28, Pro- San, and many others.	
Only slightly corrosive, relatively safe for humans when  diluted, some residual activity, much less affected by organic matter or soil. Water pH not critical.	
Hydrogen peroxide/ Peroxyacetic acid products	
Hydrogen dioxide (hydrogen peroxide)	StorOx, Oxidate, Jet Oxide, Jet Ag, SaniDate 12.0	Can be applied directly to potatoes, no residual. Low corrosiveness. With use
of heat JetAg can be used as fumigant in air system.	

Iodine, Iodophores	
Iodine, povidone iodine	Code Blue Iodine disinfectant and many others. Look for iodine in label name	Corrosive, will stain treated areas, some residual activity. Less affected by organic matter or water pH than bleach.	

Phenol- glutaraldehyde	
Phenol- glutaraldehyde	Sporocidin, Hospiseptic Disinfectant Wex-cide, Birex, etc- look for Phenol
in name	
Warning: oral poison!	
Formaldehyde	Formaldehyde	Many products available.	Potential human carcinogen! Follow OSHA directions regarding exposure	

Copper quinolinolate	
Copper 8 quinolinolate	Many products available. Purchase as generic chemical. ISK Biotech
PQ-57, PQ-80	
Good residual activity. May cause some staining.	
The first step in disinfesting surfaces contaminated with potato residues and potential pathogens is  to remove soil and potato residues by washing with soapy water and scrubbing to  remove heavy deposits of potato residue. This is an important step since many disinfectants are inactivated by soil  or organic matter and bacteria can live in the heavier residues and are protected from disinfectants. The second step is to disinfect with a labeled disinfectant. It is important to keep all surfaces wet with the disinfectant solution for 10-15 minutes and to use the highest labeled rate of the disinfectant
chemical.
