What do you understand by biological control of weeds and pests?

Biological control refers to the use of natural enemies, such as predators, parasites, or pathogens, to manage the population of pest species. In the context of weeds and pests, it involves introducing or promoting these natural enemies in order to reduce the population of the targeted species. Biological control is a sustainable and environmentally friendly approach that can help to limit the use of chemical pesticides and herbicides.
