Identifikasi dan Virulensi Fusarium oxysporum f.sp. cubense RAS 4
The aim of this study was to identify and to detect the virulence of Fusarium oxysporum f.sp. cubense (Foc) race 4. The isolates consisted of BNT-2, KD-1, U-8, BK, A-2, and A-13. Monospore isolation was done to obtain stable isolates. The detection and characteristics of isolates were observed on Ko...
