Sensitization May cause an allergic skin reaction.
Germ cell mutagenicity No information available
Carcinogenicity A low incidence of urinary tract tumors was seen in only 1 of 5 chronic studies in rats with
trifluralin. Trifluralin is not anticipated to be a carcinogenic risk to man.
Reproductive toxicity Not a reproductive toxin
STOT - single exposure No information available
STOT - repeated exposure No information available
Chronic toxicity No information available
Target Organ Effects No information available
Aspiration hazard No information available
Trifluralin has a low toxicity if swallowed. Harmful effects are not expected from swallowing small amounts.
Fertilizers may be harmful to aquatic life with short term effects, causing algal bloom and increased BOD,
depending on the amount released.
Aquatic toxicity: Trifluralin is very highly toxic to aquatic organisms (including fish and plants) on an acute basis
(LC50 or EC50 <0.1 mg/L in the most sensitive species tested).
Avian Toxicity: Trifluralin is practically non-toxic to birds on an acute and dietary basis.
Bees: Triflurlain is not toxic to bees. LD
50
>100micrograms/bee (skin and oral).
The herbicide ingredients are toxic to aquatic invertebrates. Use with care when applying to turf areas adjacent to
any bodies of water. Do not apply directly to water, or to areas where surface water is present, or to intertidal
areas below the mean high water mark. Drift and runoff from treated turf may adversely affect aquatic organisms
in adjacent bodies of water. Do not apply when weather conditions favor drift from treated areas. Do not
contaminate water when disposing of equipment washwater.
Application around a cistern or well may result in contamination of groundwater or drinking water, particularly
where soils are permeable and water table is shallow.
Persistence and degradability Trifluralin is expected to biodegrade very slowly (only 5% in 28 days in soil).
Bioaccumulation Bioconcentration potential of trifluralin is high (BCF > 3000 or Log P
ow
between 5
and 7).
Other adverse effects No information available
