Residue level and dissipation of carbendazim in/on pomegranate fruits and soil

Abstract

Carbendazim is widely used on pomegranate for control of a large number of fungal diseases. Its residue levels in/on pomegranate fruits and soil were evaluated under field conditions. The quick, easy, cheap, effective, rugged, and safe (QuEChERS) method in conjunction with liquid-chromatography mass spectrometry was used for analysis of carbendazim. Recovery of carbendazim was within 78.92-96.28 % and relative standard deviation within 3.8-10.9 % (n = 6). Carbendazim residues on pomegranate fruits dissipated at the half lives of 17.3 and 22.8 days from treatments at 500 and 1000 g active ingredient (a.i.) ha(-1), respectively. Its residues in pomegranate aril were highest on the tenth day and reduced thereafter. The residue level of carbendazim on pomegranate whole fruits from standard dose treatment was less than the EU maximum residue limit (MRL) of 0.1 mg kg(-1) at harvest. The carbendazim residues were <LOQ in the aril and field soil at harvest. The pre-harvest intervals (PHIs) of carbendazim on pomegranate were 65.4 and 103.4 days. The results of this study can be used to determine the judicious use of carbendazim for plant protection of pomegranate crop.

Newly synthesized chitosan-nanoparticles attenuate carbendazim hepatorenal toxicity in rats via activation of Nrf2/HO1 signalling pathway

“…The residual concentration of CBZ in farmland is about 0.18–1.74 mg/kg soil, while those in some fruits and vegetables were 0.37 and 0.60 mg/kg 4 . Moreover, CBZ is considered as a persistent environmental contaminant because its benzimidazolic ring which is difficult to break so, its degradation is slow 5 . Several countries have reported that CBZ is frequently detected in soil and water for 3 days to 12 months 6 , 7 .…”

Dissipation and dietary risk assessment of carbendazim and epoxiconazole in citrus fruits in China

“…The difference in half-life values among Guangxi, Zhejiang, and Hunan might be influenced by different local climate conditions. Several studies have calculated the half-lives of carbendazim in mango, 17,18 Panax notoginseng, 19 pomegranate fruits, 20 tea, 21 and celery 22 with half-lives of 1-36.67 days and epoxiconazole in rice paddy 24,25 and wheat straw 26 with half-lives of 2.9 and 39 days, respectively. These differences may be partially due to different crop varieties, different application doses, and different local climates.…”

“…A few studies have reported methods of extraction and purification of carbendazim and epoxiconazole from citrus 15 and orange juice. 16 Many studies have analyzed the dissipation of carbendazim in a variety of matrix samples such as mango, 17,18 Panax notoginseng, 19 pomegranate fruits, 20 tea, 21 and celery. 22 Safety risk assessment of carbendazim has also been carried out for mango, 17 tea, 21 celery, 22 and vegetables.…”

Residue transfer and risk assessment of carbendazim in tea

“…The t 1/2 of carbendazim was 4.6–7.3 days at the recommended and doubled dose when it was applied on grapes . The dissipation of carbendazim in pomegranate fruits followed first + first‐order kinetics with a t 1/2 of 2–2.25 days, and the residues of carbendazim were confined within the outer rind of the pomegranate, whereas carbendazim in/on pomegranate fruits dissipated much more slowly in another study showing a t 1/2 of 17.3–22.8 days and might be impacted by environmental conditions. The persistence and dissipation behavior of carbendazim were also evaluated in pre‐ and post‐harvest mango applications .…”
