Explanation:

Monoculture is a system of farming or cropping whereby a single crop is planted on a given area of land. The opposite of this system of farming is known as multiple cropping, where a variety of crops are cultivated.

One disadvantage of planting a variety of crops over a single crop in monoculture is that it increases the risk of parasite/pest attack on the crops. Parasites and pest can easily shift to the variety of crops planted in the farm.
