Abstract- In managing plant diseases, biological control is seen to be a possible substitute for pesticides and plant resistance; nevertheless, support for this approach will require a deeper comprehension of the ways in which biological control interacts with society and the environment. Infectious plant diseases pose significant threats to global agriculture, impacting crop yield, quality, and food security. Plant pathogens, including fungi, bacteria, viruses, and nematodes, are responsible for a myriad of infectious diseases affecting crops worldwide. The complex interactions between pathogens, plants, and the environment create challenges for effective disease management. Understanding the physiological basis of plant-pathogen interactions is crucial for developing targeted control strategies. Integrated Disease Management (IDM) approaches offer a multifaceted strategy for controlling infectious plant diseases. Crop rotation, sanitation, and quarantine measures play pivotal roles in preventing the spread of diseases within and between agricultural systems. An increasing number of evolutionary biologists should be included in the strategy development process. The public and governments should collaborate on the creation and application of biological control techniques that provide positive externalities.
