Given the water scarcity becoming endemic to a large portion of the globe, arid region irrigation has resorted to the use of treated, partially treated, or even untreated wastewaters. Such waters contain a number of pollutants, including surfactants. Applied to agricultural lands, these surfactants could affect the fate and transport of other chemicals in the soil, particularly pesticides. A fi...

Glyphosate isopropylamine and trifluralin are herbicides widely used in Turkish agriculture. The recommended field dose (RFD) (480 g of active ingredient l for both glyphosate and trifluralin) and 2 × RFD of these herbicides were added to the soil of olive trees (Olea europaea L., Oleaceae) growing on the Çukurova University Campus (Adana) under Mediterranean climate conditions in order to dete...

Trifluralin is a preemergent herbicide that applied to soil control annual grasses and broadleaf weeds. It widely used in cotton, Gossypium hirsutum L., production China; however, the ecological safety of its continued use controversial issue. We studied interaction trifluralin earthworms, Eisenia foetide Savigny (Annelida: Lumbricidae), provide additional information for assessing risk soils. ...

Submicromolar concentrations of several dinitroaniline herbicides have been found to specifically inhibit intracellular replication of the protozoan parasite Toxoplasma gondii. IC50 concentrations for T. gondii survival were approximately 100 nM for ethalfluralin and oryzalin and approximately 300 nM for trifluralin. Primary human fibroblasts employed as host cells for parasite culture were una...

The extensive use of herbicides in agriculture becomes an important factor in environmental pollution, especially in case of slowly degradable compounds. Some agents act on plants during a long period of time, even if a very low concentration of the herbicide remains in the soil. Here, we investigated the toxicological effect of a low concentration of dinitroaniline herbicide, trifluralin, on g...

Binding of the triazinone derivative metribuzin to thylakoid membranes was studied in depend­ ence of tem perature and trypsin pre-treatm ent of the chloroplasts. The tem perature curve of the binding constant suggests that the lipid phase of the membrane contributes to inhibitor binding. Trypsin pre-treatm ent of the membranes removes the receptor sites for the inhibitor, while the trypsin eff...

The herbicides alachlor, linuron, vernolate, and metribuzin were applied to plots treated with the nematicide fensulfothion or the insecticide phorate and planted to soybean in two locations in North Carolina. In 1976 treatment with fensulfothion + alachlor or vernolate, phorate + alachlor or metribuzin resulted in greater nematode population densities than no treatment, or treatment with fensu...

Farmers in the Midwestern United States continue to be reliant on soil-applied herbicides for weed control in crop production, and herbicide contamination of streams remains an environmental problem. The main objective of this study was to analyze trends in concentration and load of acetochlor, alachlor, metolachlor, and metribuzin in Goodwater Creek Experimental Watershed (GCEW) from 1992 to 2...

A bioassay for possible carcinogenicity of technical-grade trifluralin was conducted using Osborne-Mendel rats and B6C3F1 mice. Analysis of the technical product established the presence of 84 to 88 ppm dipropylnitrosoamine. The product was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Fifty animals of each sex were placed...
