摘  要:
应用气相色谱(电子捕获检测器-ECD)测定,研究了20%啶虫脒SP在苹果和土壤中的残留消解动态。结果表明,啶虫脒在苹果中半衰期为2.2~5.1d,在土壤中为0.14~2.6d。用量0.2g/L,施药一次,距最后一次施药21d收获苹果中啶虫脒残留量小于0.12mg/kg,建议20%啶虫脒SP在苹果上防治绣线菊蚜最多使用一次,用量为0.1~0.2g/L,安全间隔期为21d。

摘  要:
A method for the determination of mospilan residues in apple and soil was developed. Two years field trial results showed that the half-lives of mospilan in apple and soil were in range of 2.2 to 5.1 days and 14 to 2.6 days respectively. When the apple was treated by mospilan 20% SP with a dosage of 0.2 g/L for one time only,on the 21st day after the last application the final residue of mospilan in apple was below 0.12 mg/kg. The results suggested that mospilan 20% SP be used in apple at most one time at a dose of 0.1 to 0.2 g/L with a safe interval of 21 days from harvest.
