Biological control is a method used in agriculture and forestry to manage plant pests and diseases through the use of living organisms. The goal of biological control is to reduce the use of harmful chemical pesticides and improve the health of the environment, as well as the plants being cultivated. Phytopathogens, or plant pathogens, are microorganisms that cause disease in plants, and biological control can be used to control these pathogens through a number of different mechanisms. One of the key mechanisms of biological control of phytopathogens is through the use of antagonist microorganisms. Antagonist microorganisms are beneficial microorganisms that can inhibit the growth and colonization of pathogenic microorganisms. For example, some species of bacteria and fungi, such as Bacillus subtilis and Trichoderma harzianum, produce antibiotics that can inhibit the growth of phytopathogens. In addition, some species of bacteria and fungi can compete with phytopathogens for nutrients and space, effectively reducing their ability to colonize and cause disease in plants.
