Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Biopesticides usually have no known function in photosynthesis, growth or other basic aspects of plant physiology. Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use.
Plants produce secondary metabolites known as allelochemicals. Rather than participating in basic metabolic processes, they mediate interactions between a plant and its environment, often attracting, repelling, or poisoning insects. [5] [6] They also help produce secondary cell wall components such as those that require amino acid modification. [7]
Antagonism plays a critical role in agriculture, particularly in the development of biological control agent (BCAs) to manage phytopathogens and reduce reliance on synthetic pesticides. [16] Numerous microbial antagonists, including yeasts and bacteria , are isolated from diverse environments such as soil, plants, compost, and oceans for their ...

BioControl is a peer-reviewed scientific journal published by Springer Science+Business Media covering all aspects of basic and applied research in biological control of invertebrate, vertebrate, and weed pests, and plant diseases.
The IOBC serves as a resource for international organizations, for example: the European Commission on sustainable use of pesticides [1] and the status of IPM in Europe, [2] the EC Regulation of Biological Control Agents with regard to invertebrate biological control agents, [3] the Consultative Group on International Agricultural Research on IPM, [4] the European and Mediterranean Plant ...
Some produce an auxin hormone which promotes plant growth and plays a role in the life cycle of the bacteria. [citation needed] Different bacteria prefer different plants and different plant organs depending on the organ's nutritional content, and depending on the bacteria's colonization system which is controlled by the host plant.
