摘　　要：通过田间试验和室内测定研究了哒螨灵在苹果和土壤中的残留动态,应用气相色谱法测定了哒螨灵在苹果和土壤中的残留量。结果表明,哒螨灵在苹果和土壤中的半衰期分别为7.34d和8.62d。按推荐浓度50mg/L使用2次,距最后一次施药7d,哒螨灵在苹果中的残留量低于0.10mg/kg。Field experiment and residue detection were conducted to study residual dynamic of pyridaben in apple and soil. Pyridaben residues were quantified by GC. The results showed that pyridaben＇s half-lives in apple and soil were 7.34 d and 8.62 d. Spraying twice with the recommended dose of 50 mg/L, the residue in apple 7 days after the final spray was less than 0. 10 mg/kg.
