Uptake and translocation of ethofumesate in sugar‐beet plants
Pesticide Science, 1978AbstractThe uptake and translocation of 14C‐labelled ethofumesate [(±)‐2‐ethoxy‐2,3‐dihydro‐3,3‐dimethylbenzofuran‐5‐yl methanesulphonate] was studied in sugar‐beet seedlings following soil and foliar applications. After soil applications, the roots absorbed and translocated to the foliage more ethofumesate or its metabolites than did the emerging ...

Determination of Ethofumesate‐2‐hydroxy Stereolability by Dynamic HPLC
Separation Science Plus, 2018Abstract Evaluating stereolability of target chiral chemical is pivotal when developing enantioselective studies. Ethofumesate‐2‐hydroxy is one of the main metabolites of ethofumesate, a chiral herbicide currently marketed as racemate.

Interaction between Preemergence Ethofumesate and Postemergence Glyphosate
Weed Technology, 2013Greenhouse and field experiments were conducted to determine whether PRE-applied ethofumesate increased POST spray retention and weed control with glyphosate. In greenhouse studies, ethofumesate was applied PRE at rates from 0 to 224 g ai ha−1followed by POST treatment with either water or glyphosate (840 g ae ha−1) to which a red dye had been added ...

Investigating Ethofumesate-Clay Interactions for Pesticide Controlled Release
Soil Science Society of America Journal, 2012Sorption properties of clays are effective to control the mobility and availability of pesticides in soil. Adsorption/desorption mechanisms of a model pesticide (ethofumesate) on clays and organoclays were investigated to elucidate the impact of clay structural and chemical properties on clay-pesticide interactions in an aqueous environment.

Effect of dissolved organic matter on the adsorption of ethofumesate by soils and their components
Chemosphere, 1992Abstract A study was conducted to examine the effect of dissolved organic matter on the adsorption of ethofumesate by two soils of different nature and by two components of the soil colloidal fraction (montmorillonite and humic acid). The study was performed using the equilibrium dialysis method.

Species differences for stereoselective metabolism of ethofumesate and its enantiomersin vitro
Xenobiotica, 20091. The stereoselective metabolism of ethofumesate (ETO) and its enantiomers in rabbit and rat liver microsomes have been studied by chiral high-performance liquid chromatography (HPLC) method. Two metabolites were detected in both liver microsomes in the presence of beta-nicotinamide adenine dinucleotide phosphate (NADPH). 2. The T(1/2) of (+)-ETO and (

Sugarbeet tolerance of post‐emergence applications of desmedipham and ethofumesate*
Weed Research, 1976Summary:Tolerance of sugarbeet (Beta vulgaris L.‘Mono‐Hy Al') to post‐emergence treatments of ethofumesate [(±)2‐ethoxy‐2,3‐dihydro‐3,3‐dimethylbenzofuran‐5‐yl‐melhansulfonate] and desmedipham [(3‐ethoxy‐carbonylamino)phenyl‐N‐phen‐ylcarbamate] was studied in the glasshouse and in the field at several growth stages.

Response of spring cereal crops to soil residues of ethofumesate*
Weed Research, 1977Summary:For evaluation of soil residues of ethofumseate [(±)2‐ethoxy‐2,3‐dihydro‐3,3‐dimethylbenzofuran‐5‐yl‐methylsulphonate], spring barley (Hordeum vulgare L.) and spring wheat (Triticum aestivum L.) were sown in soil planted 11 months previously with sugar‐beet (Beta vulgaris L.) and previously treated with band or broad‐cast applications of the ...

Variation in ethofumesate tolerance in Lolium species and cultivars
Weed Research, 1984SummaryThe ethofumesate tolerances of seventy cultivars of Lolium perenne L., L. multiflorum Lam. and L. x hybridum Hausskn. were investigated by growing seedlings in a glasshouse in a potting compost treated with a critical level of the herbicide.

The Analyst, 1990
A procedure for the determination of low concentrations (10–4–10–5M) of the herbicide ethofumesate in aqueous solutions is described. The method is based on the hydrolysis of ethofumesate in alkaline medium at elevated temperature, azo coupling the hydrolysate with diazotised sulphanilic acid and spectrophotometric measurement of the red azo dye formed.
