Best Answer

Requirements for successful monoculture are more demanding of management skills. Closer attention to soil erosion is necessary. Soil structure problems can become severe. The farmer is completely dependent on chemical insecticides and similar methods of controling insects and diseases.

Monocultures are composed of only one strain of a particular species of crop, that will have been selectively bred by the farmer for desirable characteristics such as high yield, high productivity and resistance to pests/diseases that commonly affect such crops. However the result of this selective breeding is that genetic diversity throughout the crop is usually very low, and if the crop encounters a new strain of pest that it bears little resistance against, this vulnerability will tend to be shared throughout the population and the entire crop may become infested.

Natural ecosystems have a high genetic diversity so it is very unlikely for all of the individuals of a species to be susceptible to a particular pest.

Once a bacteria or virus becomes successful in infecting one organism,

all the monoclonal "twins" are equally susceptible.
