매실재배에서 Chlorpyrifos와 Deltamethrin의 잔류농약 변화 연구

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the changing pattern of the residue of Chlorpyrifos and Deltamethrin in Prunus mume during cultivation.
The Chlorpyrifos and Deltamethrin, which were treated by both a single-dose(safety use standard of pesticide) and a double-dose, were sprayed just one time 10 days before harvest.
We did this study to find out the changing pattern of residue as time went by. After Chlorpyrifos was sprayed, the residue was rapidly decreased, but it was decreased at a slow pace after 5 days. At the same condition, Deltamethrin was slowly decreased all the time. The decrease transition of each pesticide residue was typically decreased with a linear function. The residues were diminished exponentially.
The half-life of Chlorpyrifos in Prunus mume was 3.5 days at a single-dose treatment and 3.1 days at a double-dose treatment. The half-life of Deltamethrin in Prunus was 6.2 days at a single-dose treatment and 5.3 days at a double-dose treatment.
If the MRL(the Maximum Residue of Limit) of Chlorpyrifos in Prunus mume(1.0 mg/kg) is considered, harvests are advisable in 5 days at a single-dose treatment and 10 days at a double-dose of the pesticide. And if the MRL of Deltamethrin in Prunus mume(0.05 mg/kg) is considered, harvests are advisable in 13 days at a single-dose treatment and 20 days at a double-dose of the pesticide.
By these results, the terminal residues during cultivation stage could be predicted.
