What are pathogens in pest control?

Pathogens in pest control are defined as bacteria, viruses, or microorganisms that can cause disease in plants, animals, or humans. They play a significant role in integrated pest management (IPM) strategies, where their potential to infect and weaken or kill pests is leveraged to control pest populations. Understanding the role of pathogens is crucial for developing effective pest management techniques, as they can reduce the reliance on chemical pesticides and may offer a more environmentally friendly approach to pest control.

While the other options mention important aspects of pest management, they do not accurately define what pathogens are. The first choice pertains to beneficial organisms that support plant growth, which is a different category known as plant growth-promoting organisms. The second choice describes animal predators, which are a form of biological control but are distinct from pathogens. The last option refers to natural herbicides, which are used to suppress unwanted plant growth but do not relate to the disease-causing agents that pathogens represent. Understanding these distinctions helps clarify the specific role that pathogens play within the broader context of pest control.
