Crop destroyers are organisms that cause significant damage to agricultural crops. Blights, which are caused by fungi, bacteria, or viruses, can cause severe damage to plants, resulting in reduced yields and even complete crop failure. Locusts, which are a type of grasshopper, can also cause significant damage to crops, consuming large amounts of vegetation in a short period of time. Both blights and locusts can have devastating effects on agricultural production, making them important crop destroyers.
