The Toxin Components Study on Generic Products of Abamectin

Abstract

Abamectin is the first microbial insecticide extracted from Streptomyces avermitilis and has been registered for diamondback moth control. Not long after abamectin was registered, the generic products of abamectin started to market, and the low-cost, un-refined generic products soon out-competed the registered abamectin by a volume of more than 9 to 1. 自從阿巴汀在本省登記以來，市面上經常可購得非法進口的類阿巴汀產品，即所謂的「黑藥水」，供農民防治蔬菜害蟲使用。此類產品低價且未經精煉，所含毒性成份究竟為何，迄今仍不為人知。本研究針對此一問題於田間取得37件樣品，並逢機取樣其中23件進行成份分析，於五方面進行比較：(1)總毒性成份及含量、(2)具毒理資料之成份（B1a及B1b）分析、(3)B1a及B1b成份及比率分析、(4)不具毒理資料成份（Ala、A1b、A2a及B2a）之分析及(5)各成份間比率分佈分析。
