Applying a GLM based approach to model the influence of soil properties on the toxicity of phenmedipham to Folsomia candida

Purpose: Soil properties are the main explanation to the different toxicities obtained in different soils, due to their influence on chemical bioavailability and the test species performance itself.

Chlorophyll a fluorescence and herbicide efficacy, metabolism and selectivity

, 2006
Analysis of chlorophyll fluorescence induction curve (Kautsky curve) parameters was used for the study of the efficacy, metabolism and selectivity of ACCase, PSII and EPSPS inhibitors. Fv/Fm, Fvj and area above Kautsky curve and maximum fluorescence were

Photodegradation Des Pesticides a L'Etat Adsorbe: Photodegradation du Phenmediphame Photodegradation of Pesticides on Adsorbed Phases: Photodegradation of Phenmedipham

Environmental Technology (United Kingdom), 1995
The photodegradation of pesticides was investigated on adsorbed phases: silica, kaolin, bentonite and on a standard soil. Kinetic results show that the photodegradation of phenmedipham is dependant on the nature of the support. On silica and bentonite the degradation is immediate while the photodegradation is slow on kaolin and standard soil. Also, the

Biological monitoring of phenmedipham: determination of m -toluidine in urine

Archives of Toxicology, 2001
Phenmedipham [methyl-3-(3-methylphenylcarbamoyloxy)carbamate] is used as a herbicide, especially in the growing of sugar beet and strawberries. During metabolism of the substance in rats, the two carbamate moieties of phenmedipham are cleaved and the metabolites methyl-N-(3-hydroxyphenyl)-carbamate, m-aminophenol and hydroxyacetanilide are formed ...

Expression of a bacterial gene in transgenic plants confers resistance to the herbicide phenmedipham

Plant Molecular Biology, 1994
Tobacco plants were genetically engineered to express a detoxifying pathway for the herbicide phenmedipham. A gene from Arthrobacter oxidans strain P52 that encodes an enzyme catalysing the hydrolytic cleavage of the carbamate compound phenmedipham has recently been cloned and sequenced. The coding sequence was fused with a cauliflower mosaic virus 35S

Ozone pollution modifies the response of sugarbeet to the herbicide phenmedipham

Water, Air, and Soil Pollution, 1995
Experiments were conducted in which sugarbeet plants (Beta vulgaris L. cv. Saxon) with 2 to 3 leaves were exposed to a simulated 2 day ozone episode (100 nl l−1, 7 h d−1). Three days later, the plants were sprayed with field rate phenmedipham (1.14 kg a.i.

Response of Sugarbeets and Weeds to Phenmedipham and Two Analogues

Weed Science, 1971
Responses of weeds and sugarbeets (Beta vulgarisL.) to postemergence treatments of methylm-hydroxycarbanilatem-methylcarbanilate (phenmedipham) and two analogues were evaluated in six field studies. Phenmedipham at 1.7 kg/ha controlled foxtail millet (Setaria italica(L.) Beauv.) and kochia (Kochia scoparia(L.) Schrad.) better than 2.2 kg/ha of methylm ...
