1. Disinfectants Available to use on Mushroom Farms
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
Formaldehy
de
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.
FCS = food contact surfaces; GS = general sanitation; OM = organic matter
