“…The DT 50 values were 8.3 (95 % CI, 7.1–10.2) and 6.0 (95 % CI, 5.1–7.4) days for CAP in fields I and II, respectively, and 6.8 (95 % CI, 5.2–10.1) and 9.9 (95 % CI, 7.4–15.1) days for FBD. CAP exhibits long half-lives in perilla leaves (19.3 days [ 10 ]) because of its systemic properties [ 32 ]. However, it rapidly degrades in fruits, such as strawberry (4.7–6.4 days [ 33 ]) and tomato (3.3 days [ 34 ]).…”

“…Studies have reported the dissipation and dietary risk assessment of CAP and FBD in various plant samples, including brinjal, kale, paprika, perilla leaves, strawberries, tea leaves, and tomatoes [ [8] , [9] , [10] , [11] , [12] , [13] ]. Pesticide residue levels can vary significantly depending on whether the crops are grown in a greenhouse or in open fields.…”

BACKGROUND: Unintentional residual pesticide in soil derived from preceding crops and the transfer to succeeding crops was considered a critical barrier for positive list system (PLS). Thus, an uncertain risk is predicted for ethoprophos applied at cultivation of preceding crop (Korean cabbage) to succeeding crop (spinach). METHODS AND RESULTS: Ethoprophos was treated on soil following the recommended dose and 5 times dose according to the safe use guidelines for Korean cabbage after seeding. On the 4 days after harvesting of preceding crop, spinach was sowed. The initial residual amounts of ethoprophos on soil (7.081-19.493 mg/kg) were decreased to 3.832-7.218 mg/kg until the harvest of Korean cabbage, and then finally decreased to 0.011-0.079 mg/kg after spinach cultivation. The uptake rates of ethoprophos from soil by Korean cabbage were 0.01-0.03% and distributed to root (0.150-0.903 mg/kg) and shoot (0.021-0.151 mg/kg), respectively. The residual amounts of uptake and trans-location from preceding crop cultivated soil to spinach edible part were found to be below LOQ. CONCLUSION: The plant back internal (PBI) for ethoprophos is not recommended during sequential cultivation of leafy vegetables, since the residual amounts of ethoprophos in spinach were less than MRL (0.02 mg/kg).
