was
prepared
by
Jeneil
Biosurfactant
Company,
and
EPA
has
not
fully
evaluated
the
merits
of
the
pesticide
petition.
The
summary
may
have
been
edited
by
EPA
if
the
terminology
used
was
unclear,
the
summary
contained
extraneous
material,
or
the

A.
Product
Name
and
Proposed
Use
Practices
Rhamnolipid
biosurfactant
is
intended
for
the
prevention
and
control
of
plant
pathogenic
fungi
on
horticultural
and
agricultural
crops.
Fungal
diseases
are
often
spread
by
zoospores
that
are
transported
from
one
plant
to
another
and
from
field
to
field.
Rhamnolipid
biosurfactant
kills
zoospores
that
cause
fungal
disease,
on
contact.
Target
pests
are
any
zoosporic
plant
pathogenic
microorganisms
including
the
following
genera:
Plasmodiophora,
Polymyxa,
Spongospora,
Physoderma,
Olpidium,
Synchytrium,
Rhizophydium,
Achlya,
Aphanomyces,
Albugo,
Peronopythora,
Pachymetra,
Pythium,
Phytophthora,
Trachysphaera,
Basidiophora,
Peronosclerospora,
Plasmopara,
Pseudoperonospora,
Sclerophthora,
and
Sclerospora.
End­
use
formulations
of
rhamnolipid
biosurfactant
are
applied
through
conventional
equipment
as
a
spray,
fog,
drench
or
seed
soak
to
the
point
of
saturation,
and
can
also
be
incorporated
into
nutrient
solutions
for
hydroponic
plants
and
vegetables.
The
product
will
be
diluted
with
water
and
applied
to
growing
plants
and
agricultural
commodities
at
a
rate
of
70
to
100
parts
per
million
(
ppm).
One
enduse
formulation,
Zonix
Biofungicide
(
8.5%
active
ingredient),
is
proposed
at
this
time.

Rhamnolipid
biosurfactant,
in
particular,
causes
the
lysis
of
zoospores
of
plant
pathogens.
Zoospores,
the
unicellular,
motile
spore
stage
in
the
life
cycle
of
plant
pathogens,
are
vulnerable
to
rhamnolipid
biosurfactants
due
to
the
fact
that
the
membrane­
bound
spore
lacks
a
protective
cell
wall.
The
rhamnolipid
destroys
the
permeability
of
the
plasma
membrane
and
results
in
the
loss
of
motility
and
rapid
lysis
of
the
zoospore.
Rhamnolipid
biosurfactants
are
effective
against
all
zoosporic
plant
pathogens,
such
as
downy
mildews,
Pythium
and
Phytophthora.
Biosurfactants
are
produced
by
a
variety
of
microorganisms
and
have
been
shown
to
play
a
role
in
enhancing
bioavailability
and
biodegradation
of
petroleum
hydrocarbons,
in
the
attachment
and
detachment
of
bacteria
to
surfaces,
and
in
complexing
metals
efficiently.
Biosurfactants
have
application
in
cosmetics,
personal
care
products,
detergents,
textile
processing,
agricultural
crop
protection
products,
metal
treatment
and
processing,
leather
processing,
hard
surface
cleaning,
electronics
component
cleaning,
pulp
and
paper
processing,
paint
formulation,
hydrocarbon
recovery,
oil
tank
cleaning
and
oil
sludge
remediation.
Rhamnolipids
are
comprised
of
extracellular
natural
substances
(
glycolipids)
produced
during
a
controlled
aerobic
fermentation
process
utilizing
a
strain
of
the
bacterium
pseudomonas
aeruginosa.
Rhamnolipids
are
recovered
from
the
process
by
centrifugation,
extraction,
and
subsequent
purification.
No
bacteria
are
present
in
the
manufactured
product
and
the
production
processes
are
strict
in
quality
control
to
assure
no
live
organisms
exist.
Purified
rhamnolipids
can
be
quantified
by
weight
and
rhamnose
determination.

A
statement
of
why
an
analytical
method
for
detecting
and
measuring
the
levels
of
the
pesticide
residue
are
not
needed.
An
analytical
method
for
residues
is
not
applicable.
It
is
not
expected
that,
when
used
as
proposed,
rhamnolipid
biosurfactant
would
result
in
residues
that
are
of
toxicological
concern.

C.
Mammalian
Toxicological
Profile
Rhamnolipid
biosurfactant
has
been
evaluated
for
toxicity
through
oral,
dermal,
inhalation
and
eye
routes
of
exposure.
Studies
indicate
the
end­
use
product
is
Toxicity
Category
I
for
eye
irritation
(
diluted
end­
use
product
is
Toxicity
Category
IV
for
eye
irritation),
and
Toxicity
Category
IV
for
all
other
routes
of
exposure.
Studies
resulted
in
an
acute
oral
lethal
dose
(
LD50)
>
5,000
milligrams/
kilogram
(
mg/
kg),
acute
dermal
LD50
>
5,000
mg/
kg,
acute
inhalation
lethal
concentration
(
LC50)
2.05
mg/
L,
primary
eye
irritation
severe
at
9.5%
active
ingredient
and
slight
at
1.0%
active
ingredient,
and
primary
skin
irritation
minimal.
A
waiver
has
been
requested
for
dermal
sensitization
based
on
the
fact
that
the
active
ingredient
is
not
toxic
or
irritating
dermally,
and
a
lack
of
reported
effects
by
users
of
the
surfactant
in
a
variety
of
products.
Rhamnolipid
biosurfactants
have
been
marketed
for
over
3
years
as
an
emulsifier,
dispersant
and
wetting
agent.
Since
its
discovery,
no
incidents
of
hypersensitivity
have
been
reported
by
researchers,
manufacturers
or
users.
A
waiver
has
been
requested
for
genotoxicity
based
on
the
fact
that
rhamnolipid
biosurfactant
is
not
related
to
any
known
mutagen
and
does
not
belong
to
a
chemical
class
of
compounds
containing
known
mutagens.
The
rhamnolipid
molecules
are
simply
glycolipids
composed
of
a
rhamnose
sugar
ring
and
a
fatty
acid
tail.
Individually
these
molecules
are
not
considered
toxic
or
mutagenic.
Rhamnose
is
a
comparatively
rare
sugar
listed
by
FDA
as
a
food
additive.
Fatty
acids
are
ubiquitous
in
animals
and
plants,
and
are
the
major
source
of
energy
in
the
body.
Consequently
the
breakdown
products
of
rhamnolipids
are
of
little
toxicological
concern.
A
waiver
has
been
requested
for
90
 
day
oral
toxicity,
teratogenicity
and
immunotoxicity
based
on
the
physical
mode
of
action
of
the
product,
the
demonstrated
lack
of
oral,
dermal
and
inhalation
toxicity,
and
the
innocuous
nature
of
the
potential
breakdown
products
of
rhamnolipid
biosurfactants.
The
mode
of
action
of
rhamnolipid
biosurfactants
is
a
physical
action
on
the
plant
pathogen
rather
than
a
specific

toxic
action.
Rhamnolipid
biosurfactant
is
virtually
non­
toxic
to
rats
as
demonstrated
in
the
acute
oral,
dermal
and
inhalation
studies
submitted.
The
lack
of
mammalian
toxicity
supports
the
position
that
the
physical
action
of
rhamnolipid
biosurfactants
is
a
physical
interaction
with
the
zoospore
membrane
rather
than
a
specific
toxic
mechanism
that
might
be
of
concern.
The
chemical
structures
of
the
rhamnolipids
suggest
that
there
is
little
potential
for
chronic
toxicity,
teratogenicity
or
immunotoxicity
in
animals
or
humans
as
a
result
of
exposure.
The
rhamnolipid
molecules
are
simply
glycolipids
composed
of
a
rhamnose
sugar
ring
and
a
fatty
acid
tail.
Individually
these
molecules
are
not
considered
toxic.

D.
Aggregate
Exposure
1.
Dietary
exposure
 
i.
Food.
Dietary
exposure
from
use
of
rhamnolipid
biosurfactant,
as
proposed,
is
minimal.
The
use
of
rhamnolipid
biosurfactant
involves
low
levels
of
active
ingredient
applied
to
growing
plants
prior
to
harvest.
Residues
of
rhamnolipid
biosurfactant
are
not
expected
to
be
of
toxicological
concern.
The
rhamnolipid
molecules
are
simply
glycolipids
composed
of
a
rhamnose
sugar
ring
and
a
fatty
acid
tail.
Individually
these
molecules
are
not
considered
toxic.
ii.
Drinking
water.
Similarly,
exposure
to
humans
from
residues
of
rhamnolipid
biosurfactant
in
consumed
drinking
water
would
be
unlikely.
Rhamnolipid
biosurfactant
is
a
naturally
occurring
extra­
cellular
substance
that
is
produced
by
a
microorganism
known
to
exist
in
plant
habitats;
it
is
not
known
to
grow
or
thrive
in
aquatic
environments.
Potential
exposure
to
surface
water
would
be
negligible
and
exposure
to
drinking
water
(
well
or
ground
water)
would
be
impossible
to
measure.
2.
Non­
dietary
exposure.
The
potential
for
non­
dietary
exposure
to
the
general
population,
including
infants
and
children,
is
unlikely
as
the
proposed
use
sites
are
agricultural
settings.
However,
non­
dietary
exposures
would
not
be
expected
to
pose
any
quantifiable
risk
due
to
a
lack
of
residues
of
toxicological
concern.
Personal
protective
equipment
mitigates
the
potential
for
exposure
to
applicators
and
handlers
of
the
proposed
products,
when
used
in
agricultural
settings.

E.
Cumulative
Exposure
It
is
not
expected
that,
when
used
as
proposed,
rhamnolipid
biosurfactant
would
result
in
residues
that
are
of
toxicological
concern.
The
rhamnolipid
molecules
are
simply
glycolipids
composed
of
a
rhamnose
sugar
ring
and
a
fatty
acid
tail.
Individually
these
molecules
are
not
considered
toxic.

F.
Safety
Determination
1.
U.
S.
population.
Acute
toxicity
studies
have
shown
that
rhamnolipid
biosurfactant
is
not
toxic,
but
is
irritating
via
ocular
exposure.
Residues
of
rhamnolipid
biosurfactant
are
not
expected
to
be
of
toxicological
concern.
The
rhamnolipid
molecules
are
simply
glycolipids
composed
of
a
rhamnose
sugar
ring
and
a
fatty
acid
tail.
Individually
these
molecules
are
not
considered
toxic.
There
is
a
reasonable
certainty
of
no
harm
to
the
general
U.
S.
population
from
exposure
to
this
active
ingredient.
2.
Infants
and
children.
As
mentioned
above,
residues
of
rhamnolipid
biosurfactant
are
not
expected
to
be
of
toxicological
concern.
There
is
a
reasonable
certainty
of
no
harm
for
infants
and
children
from
exposure
to
rhamnolipid
biosurfactant
from
the
proposed
uses.

G.
Effects
on
the
Immune
and
Endocrine
Systems
To
date
there
is
no
evidence
to
suggest
that
rhamnolipid
biosurfactant
functions
in
a
manner
similar
to
any
known
hormone,
or
that
it
acts
as
an
endocrine
disrupter.

H.
Existing
Tolerances
There
is
no
U.

for
rhamnolipid
biosurfactant.
