Panama disease sexual reproduction. This causes all bananas of a single breed to be nearly genetically identical. The fungus easily spreads from plant to plant because the individual plants' defenses are nearly identical. The disease is dispersed by spores or infected material that travel in surface water. One of the biggest issues in spreading the disease is the means by which new banana plants are planted. Suckers are taken from one plant and clonally propagated to grow new trees. About 30 to 40% of suckers from a diseased plant are infected and not all show symptoms, so the chance of growing a
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.
