Biodegradation of Trifluralin in Harran Soil

Journal of Environmental Science and Health, Part B- Pesticides, Food Contaminants, and Agricultural Wastes, 2004
Degradation of trifluralin (alpha, alpha, alpha-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) was investigated in soils taken from three different locations at Harran region of Turkey under laboratory conditions. Surface (0-10 cm) soils, which were taken from a pesticide untreated field Gürgelen, Harran-1 and Ikizce regions in the Harran Plain.

Toxicology and hazard potential of trifluralin

Food and Chemical Toxicology, 1992
This paper reviews the results of toxicity studies conducted in laboratory animals to evaluate the safety of the herbicide trifluralin (TFL). The data show that TFL is slightly toxic following single oral exposure. Testing for embryotoxicity in rats and rabbits indicated no teratogenic potential, and many different mutagenicity tests showed that TFL ...

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.

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.

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 ...

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 ...

Prediction of Trifluralin Diffusion Coefficients

Weed Science, 1973
In the range of 4.4 to 49 C, there is an exponential relationship between temperature and trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) diffusion coefficients. Diffusion is low in air-dry soil for all temperatures. It increases to a maximum value when the soil has between 8 and 15% w/w soil moisture content and then decreases ...

Trifluralin Interactions with Soil Constituents

Weed Science, 1971
Concentrations ofα,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) causing 50% growth reduction (hereinafter referred to as GR50) were determined in nutrient culture and 64 simulated soils using foxtail millet (Setaria italica(L.) Beau.) as an indicator species.

Trifluralin Vapor Emission from Soil

Weed Science, 1972
Vapor ofa,a,a-trifluoro-2,6-dinitro-N,N-dipropyl-p-loluidine (trifluralin) emitted from soils was collected in xylene and assayed by gas chromatography. Increasing the trifluralin application rate in soil surface treatments from 0.56 to 4.48 kg/ha resulted in substantial increases in vaporization from soils during the 2 hr immediately after treatment ...
