Which of the following best describes pathogens?

Pathogens are best described as agents that cause disease in their host, which includes parasitic bacteria, viruses, or fungi. They are typically harmful organisms that invade host organisms, leading to various health issues. Understanding the nature of these pathogens is crucial for pest management, as they can impact both plant health and agricultural productivity. This knowledge is especially important for implementers of pest control measures, as an effective management strategy may involve preventing or controlling pathogenic organisms to maintain healthy crops. Identifying pathogens as harmful agents highlights their role in disease processes, distinguishing them from beneficial insects that promote plant growth or protect against other pests, nutrient-rich fertilizers that provide essential nutrients to plants, or insecticides designed to control pest populations.
