Analysis of herbicide residues in sugar beet and sugar

Food / Nahrung, 1988
AbstractA 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 B
In 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, 1974
A 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 ...

Residues of the herbicide diclofop-methyl in soil and wheat

2014
The residues of diclofop-methyl in the soil and wheat were investigated. A method for residue analysis of diclofop-methyl and its metabolite diclofop was developed using high performance liquid chromatographic method. The method was then used to evaluate the residue levels of diclofopmethyl in the soil and wheat. Diclofop-methyl was rapidly degraded in
