Isoxaben is not considered a primary developmental toxicant in rats and rabbits.
Developmental effects were observed at doses that caused maternal toxicity.
Neurotoxicity
2,4-D has demonstrated neurotoxicity in rats following acute and chronic
exposure at dose levels above saturation of renal clearance.
MCPP-p has been tested in acute and subchronic neurotoxicity screening
studies in rats. Neurobehavioral effects (e.g., decreased motor activity) were
observed in the acute study. Neuropathological changes were not observed in
either study.
Dicamba has demonstrated the potential to cause neurotoxicity at high doses in
laboratory animals.
Isoxaben showed no evidence of neurotoxicity in available animal studies.
Mutagenicity
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.
Isoxaben was not mutagenic or genotoxic based on the overall weight of
evidence in a battery of in vitro and in vivo tests.

Precautions
Do not allow to get into surface water, drains and ground water. Do not
contaminate surface or ground water by cleaning equipment or disposal of
wastes, including equipment wash water. Drift and runoff from treated areas may
be hazardous to aquatic organisms in adjacent sites. Do not apply when weather
conditions favor runoff or drift. Apply this product as specified on the label.
