摘要
为制订安全使用标准，采用田间试验方法研究了霉能灵在梨和土壤中的残留动态，应用ＧＬＣ法测定霉能灵在梨和土壤中的残留量。２年试验结果表明，霉能灵在梨和土壤中消解较快，其半衰期分别为６～１０ｄ和２ｄ。使用１５％ＷＰ２０００倍，施药３次，末次施药距收获间隔期为２８ｄ，霉能灵在梨和土壤中的残留量分别为０．０２９ｍｇ／ｋｇ～０．１８７ｍｇ／ｋｇ和０．５２６ｍｇ／ｋｇ～０．０７９２ｍｇ／ｋｇ。
n order to make up
the standards for safe use of Manage on pear,a fiele experiment was conducted to study the
residual dynamics of Manage in pear and soil.The residues of Manage in pear and soil were
determined by GLC.Results showed that Manage dissipated rapidly from pear and soil.Its
half-life in pear and soil were 6-10 and 2 days,respectively.The pear was sprayed three times
with Manage 15% WP at the dilution of 1:2000(75 mg a.i/liter of water).At 28 days after last
application,the final residues of Manage in pear and soil was 0.029 mg/kg and 0.0526-0.0792
mg/kg respectively.
