MSMA was not a developmental toxicant in developmental toxicity studies in rats
and rabbits.
2,4-D is not a primary developmental toxicant in rats and rabbits. Developmental
effects were observed at doses that caused maternal toxicity.
MCPP-p was not a primary developmental toxicant in rats and rabbits.
Developmental effects were observed in rats but were considered secondary to
maternal toxicity.
Dicamba was not a primary developmental toxicant in rats and rabbits.
Developmental effects were observed in rabbits but were considered secondary
to maternal toxicity.
Neurotoxicity
MSMA did not demonstrate the potential to cause neurotoxicity in standard
toxicity studies using mice, rats, rabbits and dogs.
2,4-D has demonstrated neurotoxicity in rats following acute and chronic
exposure at dose levels above saturation of renal clearance.
MCPP-p demonstrated neurobehavioral effects without correlating
neuropathological findings in an acute oral neurotoxicity study in rats.
Dicamba has demonstrated the potential to cause neurotoxicity at high doses in
laboratory animals.
Mutagenicity
MSMA was not mutagenic in a battery of in vitro and in vivo tests.
2,4-D has been tested in both in vitro and in vivo genotoxicity tests and was not
mutagenic, although some cytogenetic effects were observed.
MCPP-p was not mutagenic or genotoxic based on the overall weight of
evidence from a battery of in vitro and in vivo tests.
Dicamba did not demonstrate evidence of mutagenic potential, although, some
positive results have been reported in the published literature.

Precautions
Do not allow to get into surface water, drains and ground water. Drift or runoff
from treated areas may adversely affect non-target plants. Drift and runoff from
treated areas may be hazardous to aquatic organisms in adjacent sites. Do not
contaminate surface or ground water by cleaning equipment or disposal of
wastes, including equipment wash water. Apply this product as specified on the
label.
