生物除草剂研究与开发的现状及未来的发展趋势

The Status and Future Directions of Bioherbicide Study and Development

随着公众健康和环保意识的提高以及现代有机农业的快速发展,生物除草剂的开发越来越受到关注。目前全球正式登记或者商业化的生物除草剂产品已经有20多个,其中也不乏国际化产品。然而,由于生物除草自身的局限性,严重限制了这些产品在国际上的市场规模。本文从生物除草剂发展背景和迫切性开始,总结了生物除草剂的类型、全球生物除草剂的研发现状和未来的发展方向。重点分析了以天然活性产物为库源,开发新的生物源除草剂或以天然产物为前体合成新的化学除草剂的可行性、已有的成绩和未来的发展前景。

With enhancing of people＇s consciousness on health and environment as well as organic agriculture development, the ＂green＂ bioherbicide has being given more and more attention. Over twenty bioherbicide products have be registered or commercialized in worldwide, even some of them became successfully the international productions. However, the consumer market of these bioherbicides is still small due to the product self weakness. Here, this review covers the development necessity and urgency, classification, the global current status and future directions of bioherbicide. In addition, we mainly focus on that the practicability, achievements and the future prospects of the natural products-based bioherbicides. It is proposed that the structural diversity and different action target of natural products offer great opportunities for the exploiture of both directly used natural compounds as bioherbicide and synthetic herbicides with new target sites based on the structures of natural products.
