采集

For a long period of time, widely used in the production of components of an effective insecticide rotenone is mainly from the genus Derris root extract, collect rotenone from the root to dig down to two meters deep, the human cost of not only high-cost and easy caused by soil erosion, many of the genus Derris production has stopped growing, leading to the market with rotenone as the main active ingredient of the biological pesticide manufacturers shortage of raw material sources.

相当长一段时间，在生产上广泛使用的有效杀虫成分鱼藤酮主要是从鱼藤属植物中的根部提取，采集鱼藤酮的根要挖掘至地下达两米深，不仅人力成本耗费高，而且容易造成水土流失，不少鱼藤属植物的产区已经停止种植，导致市场上以鱼藤酮为主要活性成分的生物农药制造企业原料来源短缺。
