LGC-42153, 2-fluoro-1-[3-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)pyridin-2-yl]propyl methoxyacetate, is a new sulfonylurea herbicide for use in rice. Its breakdown and metabolism were studied in soil under flooded condition using radioactive tracers labelled at either the propyl group or the pyrimidine ring. The half-life of LGC-42153 was approximately 3.0 days. The mass balance over 120 days ranged from 94.0 to 104.2% of applied radiocarbon, and no significant amount of volatiles or… Expand
Leaching and degradation of ethametsulfuron-methyl in soil.
It was found that ethametsulfuron-methyl was more mobile in alkaline sandy Vertisol soil and neutral loamy Alfisol soil than in acidic clayey Red soil; this mobility agreed reasonably well with Freundlich soil isotherm constants. Expand
Identification of sulfonylurea biodegradation pathways enabled by a novel nicosulfuron-transforming strain Pseudomonas fluorescens SG-1: Toxicity assessment and effect of formulation.
A bacterial strain SG-1 was isolated from an agricultural soil previously treated with nicosulfuron and identified as Pseudomonas fluorescens, providing new tools for a comprehensive picture of the sulfonylurea environmental fate and toxicity of nicos sulfururon in the environment. Expand

Phytotoxic activity of pethoxamid in soil under different moisture conditions
It is suggested that the phytotoxic activity of pethoxamid in the soil primarily depends on the concentration in soil water, but thephytotoxicity activity was affected by soil moisture through the effect on absorption of this herbicide by rice seedlings. Expand
Biodegradation and toxicity of a maize herbicide mixture: mesotrione, nicosulfuron and S-metolachlor.
The results emphasize the need to take into account the active ingredient and metabolites all together for the determination of environmental fate and toxicity of pesticide mixtures. Expand
Multiple ALS Mutations Confer Herbicide Resistance in Waterhemp (Amaranthus Tuberculatus)
Three different forms of target-site–based resistance to ALS inhibitors have been identified in waterhemp, with unique patterns of cross-resistance among protein extracts derived from each biotype in response to imazethapyr, thifensulfuron, cloransulam, and pyrithiobac. Expand
An examination of the role of biochar and biochar water-extractable substances on the sorption of ionizable herbicides in rice paddy soils.
The observations stress the importance of proper consideration of soil and biochar properties before their incorporation into paddy soils, since biochar may reduce or increase the mobility of AZ and PE depending on soil properties and time of application. Expand

  • 2006
Not only the physicochemical properties and degradability of a pesticide but also the characteristics of the many phases composing a water-sediment system determine the actual pesticide behavior, and therefore it is necessary to appropriately design an experimental system by considering the real situation of the natural aqueous environment to be examined.
