Disinfectant Type

Active Ingredients

Example Trade Names

Use/Restrictions/Comments

Chlorine

Calcium/Sodium Hypochlorite

HTH, Bleach, other trade names

Approved for FCS at 200 ppm, general disinfecting at 600 ppm; chlorine not tolerant OM; corrosive; inexpensive; adjustment of pH is critical, chlorine is not effective unless pH is approx. 7.0 or slightly lower.

Iodine Based

Iodine

Various Trade names, e.g:

Rapidyne

Approved for FCS at 25 ppm; broad spectrum disinfectant for general sanitation at 100 ppm. Provides little residual; may stain porous surfaces; sanitizer of choice for hospitals; mid- level cost.  

Oxidizers

Chlorine Dioxide – various types/levels of stability

Various Trade names, e.g: Oxysan

Mildly corrosive, different complexes and types; the more stabilized chemical need acids to activate; effective under some OM load; approved for FCS at 100 ppm; GS 500 ppm.

Hydrogen Peroxide or Hydrogen Dioxide

Various Trade names, e.g: OxiDate

Unknown efficacy; initial trials suggest more effective against spores than mycelium.

Peracetic

Peracetic (peroxyacetic) acids

Active peracid chemistry;

Peracid chemistry is similar to that of the oxidizing disinfectants.

Various Trade names, e.g: Oxonia

Unknown efficacy; corrosive, expensive; labeled for FCS; check individual label for ppm. Low residual antimicrobial activity; kills broad spectrum of microorganisms.

Phenols

Combination of:

ortho-phenylphenate  (OPP) and/or some

potassium or sodium based phenol derivatives

Various Trade names, e.g., Premisan, One-stroke, Germ Warfare

Does not have FCS tolerance;

Tolerant of some OM load; Increasing OM load rapidly decreases effectiveness.

Use on nonporous surface only (NO WOOD); Use on A/C or other equipment requires thorough rinsing with potable water.

Quaternary Ammonium

Quaternary Ammonia Chlorides

Various Trade names, e.g:

Verticide, PermQuat,

SantiQuat

Clings to substances.

Stable under low OM tolerances; does not easily dissipate.

Stabilized Formaldehyde

Hydroxymethyl-n-propanediol, formaldehyde, and dimethyl benzyl ammonia chloride

Various Trade names, e.g: Lysofume

DCR

Broad spectrum, noncorrosive

Wood Preservatives

Copper-8-Quinolinolate

Propiconazole

PQ-57

Safetray

Approved for wood surfaces between crops, prior to filling.
