To determine:
Why do fungal epidemicsgenerally pose a greater risk to asexually propagated crops, an example is seedless banana, the world’s most popular fruit, is losingthe battle against two fungal epidemics.
Introduction:
Epidemics are the rapid spread of a certain disease at a particular time in a specific area affecting a large population. Epidemics can also occur in plant species, like that in human.
