Photochemical Degradation of Acifluorfen in Aqueous Solution [PDF]
Journal of Agricultural and Food Chemistry, 2001 To elucidate the photochemical behavior of diphenyl ether herbicides in superficial waters, the photodegradation of acifluorfen, 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoïc acid (CAS Registry No. 50594-66-6), was studied in water and acetonitrile. All experiments were carried out under laboratory conditions using a solar simulator (xenon arc)

Acifluorfen Sorption and Sorption Kinetics in Soil
Journal of Agricultural and Food Chemistry, 1997 Factors which influence kinetics of sorption for acifluorfen, a postemergence herbicide, in soil were evaluated. Twelve soils of varying characteristics were used in this study. Sorption kinetics experiments with 5.86 μM 14 C-labeled (19.6 Bq mL -1 ) acifluorfen were conducted for equilibration times up to 96 h.

Photochemistry and Photoinduced Toxicity of Acifluorfen, a Diphenyl-Ether Herbicide
Journal of Environment Quality, 2002 ABSTRACTPhotochemistry studies can be helpful in assessing the environmental fate of chemicals. Photochemical reactions lead to the formation of by‐products that can exhibit different toxicological properties from the original compound. For this reason the photochemical behavior of the herbicide acifluorfen (5‐[2‐chloro‐4‐(trifluoromethyl)phenoxy]‐2 ...

Influence of Temperature and Relative Humidity on the Activity of Acifluorfen
Weed Science, 1981 The influence of temperature and relative humidity on the activity of acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} on common cocklebur (Xanthium pensylvanicumWallr.) and common ragweed (Ambrosia artemisiifoliaL.) was studied in growth chambers. Treatment at high relative humidity (85 ± 5%) resulted in a significant increase

Comparison of methodologies for extraction of acifluorfen from soil
Communications in Soil Science and Plant Analysis, 2001 Efficient methods for extraction of pesticides from soil are necessary for environmental fate studies. This study examined efficiencies of methanol:water solvent systems for recovery of the herbicide acifluorfen [5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid] from soils of different properties. The applicability of supercritical fluid CO2

Identification of spore-forming strains involved in biodegradation of acifluorfen
Research in Microbiology, 1996 We isolated and identified four spore-forming bacteria from activated sludges and soil, three of which were able to degrade acifluorfen. Biochemical characteristics, DNA base composition and DNA-DNA homology indicated that the degrading strains belonged to the species Bacillus thuringiensis, Clostridium perfringens and Clostridium sphenoides.

Performance and Safety of Acifluorfen in Processing Red Beets
HortTechnologyField trials were conducted in New York during 2021 and 2022 to evaluate acifluorfen herbicide as an alternative to postemergence (POST) pigweed management for red beets (Beta vulgaris L. spp. vulgaris). Acifluorfen was applied at 0.07, 0.14, and 0.28 kg·

Effect of metal-binding ability on the adsorption of acifluorfen on soil
Journal of Agricultural and Food Chemistry, 1993 The adsorption of acifluorfen, the sodium salt of 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid, on six soils of various physical and chemical properties as well as its dependence on the exchangeable cation (Ca 2+ and Na + ) and on soil pH was studied. Adsorption isotherms conformed to the Freundlich equation.

Applicators for a Weed Pathogen plus Acifluorfen in Soybean
Weed Technology, 1987 A low-volume (21.5 L/ha) spinning disc (controlled droplet applicator) and a high-volume (187 L/ha) boom-nozzle applicator were compared in applying tank mixtures of the weed pathogenColletotrichum gloeosporioides(Penz.) Sacc. f. sp.]aeschynomene(henceforth designated C.G.A.) and acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid}
