Development of an Immunoassay for the Residues of the Herbicide Bensulfuron-Methyl
Journal of Agricultural and Food Chemistry, 2002To develop a competitive indirect enzyme-linked immunosorbent assay based on polyclonal antibodies for the detection of the sulfonylurea herbicide bensulfuron-methyl, seven structurally related haptens were synthesized. Four of them mimicking the target analyte were conjugated to keyhole limpet hemocyanin by the N-hydroxysuccinimide activated ester ...

HPLC–Residue Analysis of the Herbicide Pyridate in Cereals
International Journal of Environmental Analytical Chemistry, 1983For many reasons residue analysis of plant protecting chemicals is becoming of increasing importance. The demand of modern trace analysis techniques is to detect significantly and sensitively values down to levels in the ppb range or even less. Aggravating circumstances are the complex multicomponent sample matrices out of whom the residue analysis has

Detoxification of Herbicide Residues in Soil
Weed Science, 1985Much of the success of modern agriculture is due to pesticide technology. Because weeds pose the greatest threat to crop yields, the largest class of pesticides used today is herbicides. Herbicides include products whose active ingredients represent a wide range of chemical families; yet most constitute a minimal potential hazard to man and the ...

Influence of ageing of residues on the availability of herbicides for leaching
Environmental Pollution, 2005Losses by leaching of chlorotoluron, isoproturon and triasulfuron from small intact columns of a structured clay loam and an unstructured sandy loam soil were measured in five separate field experiments. In general, losses of all three herbicides were greater from the clay loam than from the sandy loam soil and the order between herbicides was always ...

Analysis of herbicide residues in sugar beet and sugar
Food / Nahrung, 1988AbstractA simple quantitative TLC method for the determination of the residues of herbicide inhibiting photosynthesis was compared with capillary GLC for the analysis of atrazine, chloridazone, lenacil, phenmedipham and desmedipham in sugar beet and sugar. No significant differences in the determination limit and precision of the two methods were found.

Residual effect and interval of herbicide application on soybean
Journal of Environmental Science and Health, Part BIn the burndown of Conyza spp., non selective herbicides are recurrent in soybean pre-sowing, and it is necessary to respect the time interval between the application of these products and the sowing of the crop, known as the plant back. Therefore, the objective of this study was to evaluate soybean phytotoxicity resulting from the application of ...

The detection and determination of residues of the herbicide nitrofen in vegetables
The Analyst, 1974A method for residue analysis, based on electron-capture gas chromatography following clean-up on a sulphuric acid-Celite column, is presented. The limit of detection is 10 ng g–1. Recoveries have been investigated for different kinds of vegetables. The extraction efficiency of acetonitrile versus dichloromethane was checked in a separate experiment ...
