Pesticide Residues in Table Grapes and Exposure Assessment

Journal of Agricultural and Food Chemistry, 2018
This report describes levels of 172 pesticide residues in table grapes in Turkey. A total of 280 samples of table grapes were collected from supermarkets, bazaar, and greengrocer shops located in four provinces of Turkey from August to October 2016. The samples were analyzed by liquid chromatography coupled to tandem mass spectrometry.

Pesticide Residues in Grapes, Wine, and Their Processing Products

Journal of Agricultural and Food Chemistry, 2000
In this review the results obtained in the 1990s from research on the behavior of pesticide residues on grapes, from treatment to harvest, and their fate in drying, wine-making, and alcoholic beverage processing are reported. The fungicide residues on grapes (cyproconazole, hexaconazole, kresoxim-methyl, myclobutanil, penconazole, tetraconazole, and ...

Grapes and Residues of Wine Industry

2020
The grapes are cultivated all over the world and used as a fresh fruit and for the production of juice and wine. The grape berries are very rich in bioactive molecules such as carbohydrates, fruit acids, mineral elements, nitrogenous and aroma-producing compounds, vitamins, thiamine, riboflavin, anthocyanins responsible for the colour of red wine, and ...

Dissipation, residue, and dietary risk assessment of dimethachlon in grapes

Environmental Science and Pollution Research, 2023
Dimethachlon, a dicarboximide fungicide, has gained widespread usage in Asian countries. While considered a low-toxicity fungicide, concerns regarding potential health effects, such as nephrotoxicity, have emerged. To date, neither China nor other countries have established maximum residue limit (MRL) for dimethachlon on grapes, and exposure risk ...

Behaviour of forchlorfenuron residues in grape, soil and water

Chemosphere, 2003
Persistence of forchlorfenuron residues in grape berries at harvest following its dip application as single or split doses to grape berry clusters and periodic dissipation of forchlorfenuron residues in grape berries following foliar spray application were studied. Periodic dissipation of forchlorfenuron residues following its fortification in soil and

Fate of Quinoxyfen Residues in Grapes, Wine, and Their Processing Products

Journal of Agricultural and Food Chemistry, 2000
Quinoxyfen is a new fungicide that belongs to the family of the quinolines, recently introduced to control powdery mildew (Uncinula necator). In this paper the fate of quinoxyfen residues from vine to wine and in their processing products was studied.

Pesticide Residue Management in Grapes

2013
Nearly all insecticides have the potential to significantly alter ecosystems, many are toxic to humans, and others are concentrated in the food chain. Insecticides are classified in several different ways. Systemic insecticides are incorporated by treated plants. Insects ingest the insecticide while feeding on the plants. Contact insecticides are toxic

Modeling of the devolatilization kinetics during pyrolysis of grape residues

Bioresource Technology, 2012
Thermo-gravimetric analysis (TGA) was performed on grape seeds, skins, stalks, marc, vine-branches, grape seed oil and grape seeds depleted of their oil. The TGA data was modeled through Gaussian, logistic and Miura-Maki distributed activation energy models (DAEMs) and a simpler two-parameter model.

Pesticide residues in liquid pekmez (grape molasses)

Environmental Monitoring and Assessment, 2007
In this study 32 pesticide residues and eight polybrominated diphenlyl ether (PBDE) congeners were measured in seven liquid samples from Kahramanmaraş, Turkey. A new method based on the best recovery was column extraction with n-hexane/acetone followed by gas chromatography electron-capture detection (GC-ECD), and mass spectrometry (GC-MS).

Pesticide Residue Management in Grapes

Indian Journal of Entomology
A laboratory experiment was conducted in completely randomized design (CRD) to evaluate the effectiveness of various decontamination methods in removing pesticide residues from grapes during 2022-2023. Organically grown grape plants at fruiting stage were selected from Cumbum, Theni district of Tamil Nadu and sprayed with a mixture of eleven pesticides
