Biological control, in gardening and agriculture, is the use of biological agents to control pests, plant diseases, and unwanted plants from a planting area.
This may be accomplished by using predators, in the case of pests, or other insects to cause disorders in the case of unwanted plants or species that actually consume the unwanted plants.
The object of biological control is not to completely eradicate pests, diseases or weeds, but instead to manipulate and emulate natural checks and balances that exist in nature. It is a more holistic approach to gardening and agriculture.
