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
Crop scouting planting date, planting rate (spacing), row width, tillage operations, crop yields, pesticide names, rates, application dates and who applied them, fertilizer and lime applications and rates, weather patterns, soil type, soil test records (N, P, K, percent organic matter, and pH), irrigation availability, major pest problems, and anything else that could make scouting more effective. This history is very important when assessing signs of crop injuries, because they are generally ambiguous since similar abnormalities can have unrelated causes. It is best to always be prepared when entering the field, as one never know what kind of issues one will find.
