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 residues in grapes and during vinification process

Food Control, 2010
Abstract Pesticide residues in vinification process of two white and two red grapevine varieties were monitored during the 2007 vintage. Crushed grapes, cake, must, lees and wine were sampled during the vinification process. Additionally, grapes were sampled during the ripening process.

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

Pyrolysis of maize, sunflower, grape and tobacco residues

Journal of Chemical Technology & Biotechnology, 1997
Pyrolysis of four agricultural residues (maize, sunflower, grape and tobacco) has been carried out in order to quantify their energy content. The main characteristics of the charcoals formed and the nature and quantity of gases produced have been determined. The process was studied batchwise by varying the reaction time (15–60 min) and temperature (400–

Studies on the Residue of Hydrogen Cyanamide in Grape Berries

Bulletin of Environmental Contamination and Toxicology, 2009
Multilocational field trials were conducted in grapevines at four different locations by applying hydrogen cyanamide 50% SL during 2006-2007. In order to determine the residue of hydrogen cyanamide in grape, hydrogen cyanamide 50% SL was applied to the freshly pruned grapevines at the rate of 1.20% a.i./L, 2.40% a.i./L, 4.80% a.i./L along with ...

Diazinon residues and degradation kinetics for grapes under field conditions

Journal of Environmental Science and Health, Part B, 2013
The dissipation of diazinon (O,O-diethyl O-2-isopropyl-6-methylpyrimidin-4-yl phosphorothioate) in grapes was investigated to determine its pre-harvest interval (PHI). Diazinon was applied to grapes at the recommended dosage (0.9 g a.i. L(-1)) and twice the recommended dosage (1.8 g a.i. L(-1)) three times, at the fruit formation stage, the sour stage,

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.

Field Trials To Determine Residues of Chlozolinate in Table Grapes

Journal of Agricultural and Food Chemistry, 2000
Chlozolinate (Serinal) is a dicarboximide fungicide used in southern European countries principally on grapes. Maximum residue levels have not yet been set by FAO/WHO and are under evaluation in the EU. Field trials have been carried out in Greece on two varieties of table grapes (Cardinal and Victoria) during two consecutive years to assess residues ...

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.
