A field study of the use of the new fungicide triadimefon (Bayleton) on grapes has indicated that residue levels of 0.01 ppm may be expected on the ripe fruit in spite of the 60-75 day interval from spray to harvest. Triadimefon and its primary metabolite triadimenol (Baytan) have been characterized by gas chromatography and mass spectrometry to provide identification down to a detection level of 0.001 ppm. Recovery studies on these fungicides have indicated that they are completely extracted by the single multi-residue analytical methodology presently in use for monitoring fresh produce.
一项关于新型杀菌剂三唑酮（百理通）在葡萄上使用情况的田间研究表明，尽管从喷雾到收获间隔60 - 75天，但成熟果实上的残留水平预计仍可达0.01 ppm。已通过气相色谱法和质谱法对三唑酮及其主要代谢物三唑醇（拜耳坦）进行了表征，以实现低至0.001 ppm检测水平的鉴定。对这些杀菌剂的回收率研究表明，它们可通过目前用于监测新鲜农产品的单一多残留分析方法完全提取出来。
