The inhibitory effects of Chinese leek(Allium tuberosum) on Fusarium oxysporum f. sp. cubense (Foc) and on Fusarium wilt incidence were studied in order to identify a potential efficient way to control the disease. Adopting the rotation system of Chinese leek-banana reduced the Fusarium wilt incidence and disease severity index by 88 %-97 % and 91 %-96 %, respectively, improved the crop value by 36 %-86 %, in an area heavily infested by Foc between 2007 and 2009. As a result of inoculation in the greenhouse, Chinese leek treatment reduced disease incidence and the disease severity index by 58 % and 62 %, respectively in the variety Baxi (AAA) and by 79 % and 81 %, respectively in the variety Guangfen NO.1 (ABB). Crude extracts of Chinese leek completely inhibited the growth of Foc race 4 on Petri dishes, suppressed the proliferation of the spores by 91 % and caused 87 % spore mortality. The findings of this study suggest that Chinese leek has the potential to inhibit Foc growth and Fusarium wilt incidence. This potential may be developed into an environmentally friendly treatment to control Fusarium wilt of banana.
为了找到控制香蕉枯萎病的有效方法，研究了韭菜对尖孢镰刀菌古巴专化型（Foc）及香蕉枯萎病发病率的抑制作用。在2007年至2009年期间，在Foc严重侵染的地区采用韭菜-香蕉轮作系统，香蕉枯萎病发病率和病情严重程度指数分别降低了88%-97%和91%-96%，作物产值提高了36%-86%。温室接种结果表明，韭菜处理使巴西蕉（AAA）品种的发病率和病情严重程度指数分别降低了58%和62%，使广粉一号（ABB）品种的发病率和病情严重程度指数分别降低了79%和81%。韭菜粗提物在培养皿中完全抑制了4号生理小种Foc的生长，孢子增殖抑制率达91%，孢子死亡率达87%。本研究结果表明，韭菜具有抑制Foc生长和香蕉枯萎病发病率的潜力。这种潜力可开发成一种控制香蕉枯萎病的环保型防治方法。
