什么是除蟲菊?


除蟲菊(Pyrethrum cinerariaefolium Trev.)是一種菊科菊屬植物,原產于中東地區,1876年引進美國,其后 曰本、非洲、南美國家廣泛栽培,形成產業。1940年非洲肯尼亞和坦桑尼亞先后引進,1976年澳大利亞引進,逐漸發展成非洲和澳大利亞兩大規模化種植區,至今已有超過150年的栽培和使用歷史。我國由中科院昆明植物研究所于上個世紀九十年代引進成功。相繼在云南曲靖、紅河、玉溪等地規模化種植,經過近十年的發展,云南已發展成世界第三大除蟲菊生產地,推廣種植面積達到6萬畝,產品品質得到國際認可。

除蟲菊是世界上唯一集約化種植的殺蟲植物,其花朵中含有高效的殺蟲活性物質,通稱除蟲菊素(pyre- thrins),由六種結構相似的化合物組成。由于除蟲菊素源于天然,在自然界中很容易降解,在人及動物體內沒有積累的記錄,不會沿食物鏈傳遞,不污染使用空間,因此被世界公認為安全有效的殺蟲劑,盡管其生產成本比化學合成殺蟲劑高,但仍然受到歐、美、日等發達國家的青睞,廣泛應用。
