Persistence and decontamination studies of chlorantraniliprole in Capsicum annum using GC–MS/MS

Abstract

Chlorantraniliprole, a new systemic insecticide of anthranilic diamide class gaining popularity among farmers for its effective control of Lepidoptera pest particularly in vegetables. Thus monitoring of chlorantraniliprole (CAP) leftover in vegetables is required and to this end eco-friendly, cost effective, selective and accurate method was developed and validated for quantification of its left over in chilli fruit using gas chromatography-tandem mass spectrometry (GC-MS/MS) in SCAN/MRM mode with a triple Quadrupole analyzer. Two MS-MS transitions were acquired to ensure the reliable quantification and confirmation of the analyte. All calibration curve showed a good linear relationship (r [ 0.99) with in test ranges (0.005-0.5 lg ml-1). To study its persistence, half-life, waiting period and decontamination behavior the field trial were performed at recommended dose and its double by Central Insecticide Board and Registration Committee (CIBRC). Initial deposits of CAP at recommended (T1) and double (T2) the recommended doses revealed 3.16 and 4.18 mg kg-1 with their respective half-lives 1.18 and 2.05 days respectively. According to maximum residual limit i.e. 0.03 mg kg-1 by FSSAI, residues persists up to 7th and 15th day if sprayed at fruit setting stage. The extent of removal of CAP using simple decontamination approach showed 62-67% reduction on maximum residue.

Persistence, dissipation behavior and dietary risk assessment of a combi-product of chlorantraniliprole and λ-cyhalothrin in/on pigeonpea (Cajanus cajan L.)

“…The climate of this zone is typically sub-tropical, characterized by humid and warm monsoon with heavy rains, quite cold winter and fairly hot summer. The present finding on DT 50 of chlorantraniliprole is differing from the results reported with DT 50 for cauliflower 1.25–1.36 days ( Kar et al., 2012 ), tomato 3.30 days ( Malhat et al., 2012 ) okra 1.60–1.70 days ( Vijayasree et al., 2015 ), brinjal 1.58–1.80 days ( Vijayasree et al., 2015 ), green chilli 1.58–1.80 days ( Ahlawat et al., 2019 ), 1.26 days ( Paramasivam, 2020 ). This variation might be the resultant of the prevailing environmental factors and processes viz., temperature, relative humidity, volatilization and photo-degradation at field conditions ( Dong et al., 2011 ; Kar et al., 2012 ; Zhang et al., 2012 ; Solanki et al., 2019 ; Paramasivam, 2020 ) which are not consistent in different geographical regions.…”

Dissipation Kinetics, Effect of Household Processing, and Dietary Risk Assessment of Chlorantraniliprole Residue in Bitter Gourd and Soil

“…In capsicum, chlorantraniliprole residue levels were 3.16 and 4.18 mg kg -1 on 0 day after treatment at 30-60 g a.i. ha -1 (Ahlawat et al 2019). In tomato fruit the initial residue concentration of chlorantraniliprole was 2.31 mg kg -1 and reached BLQ (0.01 mg kg -1 ) after 21 days of application at 30 g a.i.…”

“…ha -1 . In capsicum, chlorantraniliprole residues were eliminated up to 68 per cent by NaCl (5%) followed by hot water and plain tap water treatment which were in the range of 55-58 per cent (Ahlawat et al 2019). In vegetable cowpea, lime and vinegar were more effective in removing chlorantraniliprole residues (87.47-91.70%) (Vijayasree et al 2013).…”

Extraction and determination of flubendiamide insecticide in food samples: A review

“…Chlorantraniliprole was the first commercialized diamide and exhibits an exceptional activity against lepidopteran pests ( European Food Safety Authority et al, 2019 ; Kadala et al, 2019 ; Zhou et al, 2019 ; Jouraku et al, 2020 ; Satpathy et al, 2020 ). It activates ryanodine receptors by stimulation of calcium release from the sarcoplasmic reticulum of muscle cells causing impaired regulation, paralysis, and ultimately death of target species ( Ahlawat et al, 2019 ; Chen et al, 2019 ; He et al, 2019 ; Héma et al, 2019 ; Jallow et al, 2019 ; Plata-Rueda et al, 2019 ; Silva et al, 2019 ; Passos et al, 2020 ; Shah and Shad, 2020 ; Williams et al, 2020 ). However, the researcher continued to pursue a wide range of polar groups on the anthranilic core with an emphasis on nitrile substitution ( Barrania, 2019 ; Bolzan et al, 2019 ; Carscallen et al, 2019 ; Mao et al, 2019 ; Gao et al, 2019 ; Meng et al, 2019 ; O'Neal et al, 2019 ; Sharma et al, 2019 ; Sreedhar, 2019 ; Truong and Pessah, 2019 ; Jiang et al, 2020 ).…”
