Bananas are planted as a staple food, important cash crop and
major export crop in many tropical and subtropical countries[1].
Banana fusarium wilt disease, caused by the fungusFusarium oxysporumf. sp.cubense(FOC), has been a known problem with banana
production early in 1874[2]. However, the disease has only been a
recent problem to Cavendish production, which comprises about
90% of the banana industry in south China [3]. An area of
200,000 ha in Guangdong and Hainan provinces have been affected
by the disease and planters are suffering from vast economic losses
[4].
Control of fusarium wilt disease is difficult because the causal
pathogen can survive for many years as chlamydospores in soi
