Abstract
A Possibility of using Antagonistic Bacterial Isolates in Controlling Fusarium Wilt of Chrysanth (Chrysanthemum sp.)
Highlights
Chrysanth (Chrysanthemum sp.) is one of the most popular ornamental plants, with relatively high economic value and future marketing prospect
This study examined two bacterial isolates SP1 and SP7R to control Fusarium wilt and to increase chrysant growth performance
Dual culture assay on antagonistic bacterial isolates against F.oxysporum
Summary
Chrysanth (Chrysanthemum sp.) is one of the most popular ornamental plants, with relatively high economic value and future marketing prospect. The domestic and foreign market demand is increasing every year (Arjana et al, 2015). One of the problems in chrysanth cultivation is fungal disease. Disease caused by Fusarium oxysporum or Fusarium wilt may render the cultivation of chrysanths in farms due to the severe disease intensities and attacks. Fusarium oxysporum is a soil-borne fungal pathogen that can survive in the soil for 8-20 years in the form of chlamydospores which are difficult to control. Mechanism of Fusarium wilt is by blocking the significant flow of water in xylem tissue of chrysanths, causing the leaves to turn yellow and wilt, and the plants die, suffering from inadequate water and nutrients (Singh et al, 2014)
