Abstract

Inhibitory effects of Chinese leek(Allium tuberosum) on growth of Fusarium oxysporum f.sp.cubense race4(Foc4) and on incidence of Fusarium wilt disease in banana were studied with Baxi(AAA)and Guangfen No.1(ABB) as experiment materials.The results showed that the crude extract of Chinese leek significantly inhibited the growth and destructed cell structure of Foc4 mycelium,restrained spore germination and caused spores dead.Inoculation of potted bananas in greenhouse showed that compared with the control,Chinese leek treatment reduced the disease incidence and the disease severity index by 80.0% and 88.9% in Baxi(AAA),and by 60.0% and 75.0% in Guangfen No.1(ABB),respectively.The findings revealed that Chinese leek had high antifungal effects on Fusarium wilt in bananas.
