Biological Control vs. Chemical Control: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 18, 2024
Biological control uses natural predators or agents to manage pests, while chemical control employs synthetic chemicals for pest eradication.

Key Differences

Biological control relies on the use of living organisms, such as predators, parasites, or pathogens, to suppress pest populations. In contrast, chemical control involves the application of synthetic chemicals, typically pesticides, to kill or repel pests.

Biological control aims to be environmentally friendly, often targeting specific pests without affecting other species or the environment. Conversely, chemical control can have broader impacts, potentially harming non-target species and the environment due to its less selective nature.

Biological control methods are generally considered sustainable as they often lead to long-term pest management. On the other hand, chemical control can lead to issues like pest resistance, requiring more potent chemicals or frequent applications.

Implementing biological control can be more complex and costly initially but may offer cost-effective long-term benefits. Chemical control, while often readily available and quick-acting, can become costly over time, especially with the development of resistance in pests.
