Panama disease new, already infected plant is fairly high. Finally, the disease is known to infect certain weeds without showing symptoms, meaning it can survive in the absence of banana plants and remain undetected in a place where bananas are planted later. FOC is thought to persist only asexually, as a teleomorph or sexual phase has not been found and no recombinant genotypes have been observed. This means that the survival and dispersal of the disease relies on purely asexual spores and structures. The disease survives in chlamydospores which are produced as the plant dies and can survive in the soil for
