What approach involves the use of microorganisms to manage diseases?

The approach that involves the use of microorganisms to manage diseases is biological control. This method utilizes beneficial microorganisms, such as bacteria, fungi, and viruses, to suppress or antagonize plant pathogens. By enhancing or introducing these beneficial organisms into the environment, it is possible to reduce the incidence of diseases caused by harmful pathogens without relying on synthetic chemicals. This approach is sustainable and promotes ecological balance, making it especially valuable in ornamental and turf management.

In biological control, the focus is on harnessing natural processes and organisms rather than applying chemical pesticides, which is the approach taken in chemical control. Integrated Pest Management (IPM) is a broader strategy combining various pest management techniques, including biological, cultural, physical, and chemical methods, to achieve effective pest control. On the other hand, mechanical control refers to the physical removal or management of pests without the use of chemicals or biological agents. Understanding these distinctions helps clarify why biological control is the correct approach in the context of using microorganisms to manage diseases.
