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
Cover crop et al. 2000). Species in the Brassicaceae family, such as mustards, have been widely shown to suppress fungal disease populations through the release of naturally occurring toxic chemicals during the degradation of glucosinolade compounds in their plant cell tissues (Lazzeri and Manici 2001). Some cover crops are used as so-called "trap crops", to attract pests away from the crop of value and toward what the pest sees as a more favorable habitat (Shelton and Badenes-Perez 2006). Trap crop areas can be established within crops, within farms, or within landscapes. In many cases the trap crop is grown during the same
