살균제 picoxystrobin, pydiflumetofen 및 pyraclostrobin의 갓 중 경시적 잔류량 변화와 식이섭취 노출기여도 평가

초록

Leaf mustard (Brassica juncea), cultivated in a greenhouse, was evaluated in our study for dietary exposure to picoxystrobin, pydiflumetofen, and pyraclostrobin and the corresponding residual dissipation. Leaf mustard was treated at weekly intervals to three pre-harvest applications of a 2,000-fold dilution of 25% picoxystrobin suspension concentrate (SC) along with a 4,000-fold dilution of 18.3% pydiflumetofen SC and 22.9% pyraclostrobin emulsifiable concentrate (EC). The initial residues in the leaf mustard were 7.08 ± 1.03 mg kg⁻¹ for picoxystrobin, 4.70 ± 0.72 mg kg⁻ for pydiflumetofen, and 5.55 ± 0.60 mg kg⁻¹ for pyraclostrobin with 50% dissipation times 1 (DT50) of 6.5, 3.9, and 3 days, respectively. The estimated daily intake (EDI), based on the initial residues, was below 1% of the acceptable daily intake (ADI).
