Toxicokinetics of trifluralin in rainbow trout

Aquatic Toxicology, 1993
Abstract Rainbow trout weighing 80 g were statically exposed at 12°C to 2 ng/ml 14C-trifluralin (TF), a widely used herbicide. After various exposure times, TF was determined in exposure water, plasma, and carcass homogenate; the total amount of metabolites formed was also estimated.

Antibody for detection and quantification of trifluralin

International Journal of Radiation Applications and Instrumentation. Part B. Nuclear Medicine and Biology, 1989
An antibody specific to trifluralin can be produced by first substituting a soluble, straight chain amino acid for a propyl group of α,α, α-trifluoro-2,6-dinitro-N-N-dipropyl-p-toluidine. The trifluoro group at the 4 position, the nitro group at the 2 position and the other nitro group at the 6 position are left exposed.

Delayed Incorporation of Trifluralin and Nitralin

Weed Science, 1973
Trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) required more thorough soil incorporation with a disk, probably to prevent loss by volatility, than did 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin). Mechanical incorporation of nitralin could be delayed for 96 hr after application, whereas trifluralin needed to be ...

The Detection of Trifluralin Vapors in Air

Weed Science, 1969
The volatilization of α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) from a Miller clay and commercial sand was determined by analysis of air samples above the soils. The method requires no extraction of soil or traps and is sensitive to approximately 8 ppm of trifluralin in air.

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.

Soil Enrichment Studies with Trifluralin

Weed Science, 1975
Soil enrichment studies were conducted with trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) with and without exogenous carbon and nitrogen. From 72 bacterial isolates obtained, eight representative ones were tentatively identified as members of the genusPseudomonasbased on size, shape, Gram reaction, and reaction on fluorescent and ...

Simulation of Trifluralin Diffusion in the Soil

Transactions of the ASAE, 1984
ABSTRACT A computer program was developed to simulate diffusion of the herbicide trifluralin (a,a,a,-trifluoro-2,6-dinitro-A^,A^-dipropyl-p-toluidine) between herbicide bands in the soil. Diffusion of trifluralin was simulated for various band heights, band spacings, and depths of placement.

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 ...

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.

Differential Phytotoxicity of Trifluralin and Nitralin

Weed Science, 1971
Comparative phytotoxicity ofα,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) and 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin) on several plant species indicated trifluralin was more toxic than nitralin to the shoots while nitralin was more toxic than trifluralin to the roots.
