Prochloraz residue levels in ginger submitted to Sportak 450 CE" postharvest treatment

Abstract

A preliminary study was conducted to determine the residue levels of prochloraz in ginger samples treated with Sportak 450 CE  (prochloraz as active ingredient) under laboratory conditions and cold-storage for 15 days at 10°C and 89% RH. Sampling was carried out at 10 and 15 days after Sportak 450 CE  dip treatment (450 and 900 µg mL -1 ). Pesticide residues were determined by GC-ECD. During the study, residue levels in ginger ranged between 3.6 and 10.6 mg Kg -1 for prochloraz.

Rapid and sensitive determination of the prochloraz residues in the cultivated mushroom, Agaricus bisporus (Lange) Imbach

“…33 De Paoli et al (1997) used the GC-ECD method for determination of prochloraz in the form of 2,4,6-trichlorophenol in vegetables, fruits and wheats and found that the LOD ranged from 10 to 500 mg kg À1 and recovery was in the region of 72-102%. 36 When compared to the methods used in the studies mentioned above, the method used in this study was more sensitive than those used in the studies mentioned above in terms of the LOD and LOQ levels. 34 They found that LOQs were 100 mg kg À1 (LC-MS) and 500 mg kg À1 (LC-UV).…”

“…(2006) determined the prochloraz residue levels in ginger, as 2,3,4-trichlorophenol, and they found that LOD and LOQ using the GC-ECD method were 100 and 200 mg kg À1 , respectively. 36 When compared to the methods used in the studies mentioned above, the method used in this study was more sensitive than those used in the studies mentioned above in terms of the LOD and LOQ levels.…”

“…Liu et al (2009) determined the prochloraz residue in mushrooms with SPE-HPLC and found the LOD level to be 38 mg kg À1 . 35 Polese et al (2006) determined the prochloraz residue levels in ginger, as 2,3,4-trichlorophenol, and they found that LOD and LOQ using the GC-ECD method were 100 and 200 mg kg À1 , respectively. 12 Blasco et al (2002) developed LC-MS and LC-UV methods to determine prochloraz in fruits and vegetables.…”

Gas Chromatographic Determination of Prochloraz in Ten Herbal Medicines

“…Most of them were on vegetable, fruit, and cereals [2][3][4][5][6][7][8][9][10][11][12][13][14][15], some is on soil and water [16,17]. It is not found on herbal medicines.…”
