Metabolism of trifluralin in the rat and dog

Toxicology and Applied Pharmacology, 1966
Abstract The metabolism of trifluralin (2,6-dinitro- N,N -di- n -propyl-α,α,α-trifluoromethyl- p -toluidine), a preemergence herbicide, was studied in rats. About 80% of an oral dose of trifluralin was found to be excreted in the feces, while the remaining portion appeared in the urine. Unchanged trifluralin was isolated from the feces. Oral doses of

Flax Response to Trifluralin

Weed Technology, 1987
Experiments were conducted in the greenhouse and in the field to determine the influence of flax (Linum usitatissimumL.) seeding depth on tolerance to trifluralin [2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)benzenamine]. Flax stand and fresh weight generally decreased as flax seeding depth increased within or below trifluralin-treated soil.

Environmental Fate of Trifluralin

1997
Trifluralin, a preemergence, soil-applied and soil-incorporated herbicide, has been in agricultural use since 1963. The environmental chemistry and fate of dinitroaniline herbicides, including trifluralin, has been studied extensively in agricultural soils. Probst et al.

Effect of Trifluralin on Mitosis

Weed Science, 1972
The compound α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) inhibited mitosis in onion(Allium cepaL. ‘Yellow Globe’) and wheat(Triticum aestivumL. Thorn’) root tips. Photomicrographs showed that trifluralin affected mitosis in the same manner as colchicine.

Trifluralin Effect on Pisum — Rhizobium Relationship

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1978
Trifluralin inhibited root and shoot elongation of Pisum sativum plant and caused isodiametric increase in cell volume of both tissues. The water content of the plant was not affected. The weedicide inhibited also growth and O2 uptake of Rhizobium leguminosarum, isolated from Pisum plant.

Behavior of trifluralin in aquatic model ecosystems

Bulletin of Environmental Contamination and Toxicology, 1980
These data illustrate the variation that can be obtained when using different model ecosystem designs in studying the behavior of pesticides in the aquatic ecosystem. These differences were probably related to the rapid metabolism and degradation of soil-incorporated trifluralin in the first experiment and to the continuous input of trifluralin in the ...

Aerobic and anaerobic degradation of profluralin and trifluralin

Journal of Environmental Science and Health, Part B, 1980
The degradation of profluralin [N-(cyclopropylmethyl)-alpha,alpha,alpha-trifluoro-2,6-dinitro-N-propyl-p-toluidine] and trifluralin (alpha,alpha,alpha-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) was studied under aerobic and anaerobic soil conditions.

Oncogenicity study of trifluralin in B6C3F1 mice

Food and Chemical Toxicology, 1991
B6C3F1 mice were maintained for 24 months on diets containing 0, 563, 2250 or 4500 ppm trifluralin. These dietary concentrations corresponded to daily doses of approximately 70, 285 or 570 mg/kg body weight, respectively. The control group contained 120 mice/sex and treated groups consisted of 80 mice/sex. There were no treatment-related effects on the
