説明
Trifluralin is a dinitroaniline herbicide that is approved for
preemergence use to control broadleaf weeds in a variety of
crops and plants. First approved nearly 50 years ago, trifluralin
is a common commercially available herbicide which is used
extensively in the United States and other countries. In the early
2000s, trifluralin was banned in Europe following reports of
persistence in soil and groundwater leading to concerns of
increased risk for toxicity. In general, trifluralin is viewed as
a safe herbicide when used according to the instructions.
Minimal to no toxicity has been reported in humans following
either oral, dermal, or inhalation exposure. There is some
evidence that once trifluralin enters the soil and groundwater, it
undergoes a complex and extensive series of metabolic steps
and can exist as multiple intermediaries depending on the
extent of the degradation. This has led to findings that trifluralin
may have elevated toxicity in certain aquatic wildlife as particular
species of fish and tadpoles have displayed biomarkers of
trifluralin toxicity following exposure. Larger vertebrates such as
canines have also demonstrated toxicological profiles suggesting
an elevated toxicity compared to humans.
化学的特性
Trifluralin is an orange crystalline solid.
使用
Trifluralin is a herbicide, first approved in 1963, for control of
annual grasses and broadleaf weeds on a variety of crops.
Trifluralin is registered for nonfood uses including residential use. Trifluralin comes in a variety of formulations and is
applied as a soil-incorporated treatment.
定義
ChEBI: A substituted aniline that is N,N-dipropylaniline substituted by a nitro groups at positions 2 and 6 and a trifluoromethyl group at position 4. It is an agrochemical used as a pre-emergence herbicide.
一般的な説明
Yellow-orange crystalline solid. Denser than water and not soluble in water. Hence sinks in water. Melting point 48.5-49°C. Used as a selective pre emergence herbicide.
反応プロフィール
Trifluralin is a trifluoromethyl dinitroaniline derivative. Dinitroaniline has a record of industrial explosions. Nothing has been reported implicating Trifluralin in any such accidents. This may be because of the trifluoromethyl substitution may mitigate the instability of the molecule. However, care should be taken in the extremes of heat, shock, and friction sources that may trigger an explosive release of energy.
健康ハザード
Dust may irritate eyes. No toxic symptoms have been observed during the manufacture and use of Trifluralin.
火災危険
Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride gas may be formed in fires.
农业用途
Herbicide: Trifluralin is a selective, pre-emergence herbicide
used to control many annual grasses and broadleaf weeds
in a large variety of tree fruit, nut, vegetable, and grain
crops, including soybeans, sunflowers, cotton, and alfalfa.
It is also used on rights-of-way, on set-aside land (i.e., arable land temporarily taken out of use). A general use pesticide (GUP). Not approved for use in EU countries
.
Registered for use in the U.S.

不和合性
Trifluralin is a trifluoromethyl dinitroaniline
derivative. Dinitroaniline has a record of industrial
explosions. Nothing has been reported implicating trifluralin
in any such accidents. This may be because of the
trifluoromethyl substitution may mitigate the instability of
the molecule. However, care should be taken in the
extremes of heat, shock, and friction sources that may
trigger an explosive release of energy. Fluorocarbons
can react violently with barium, potassium, sodium.
廃棄物の処理
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All
federal, state, and local environmental regulations must
be observed. Trifluralin does contain fluorine, and therefore
incineration presents the increased hazard of HF in
the off-gases. Prior to incineration, fluorine-containing
compounds should be mixed with slaked lime plus
vermiculite, sodium carbonate or sand-soda ash mixture
(90-10).
