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
Trap crop ground cover had the same disruptive effect on eight pest species from four insect orders. An experiment showed that 36% of cabbage root flies laid eggs beside cabbages growing in bare soil (which resulted in no crop), compared with only 7% beside cabbages growing in clover (which allowed a good crop). Also that simple decoys made of green card disrupted appropriate landings just as well as did the live ground cover. Trap crop A trap crop is a plant that attracts agricultural pests, usually insects, away from nearby crops. This form of companion planting can save the main crop from
