Biocontrol is the control of the living organisms with the application of another. The usage of biocontrol agents is also known as biological control and are mostly used for the decrease of pests and produce yields free of pests. The biocontrol approaches are a continuing method and utmost notably, a self-supporting one helping in the control of invasive plant species. Weed invasion and pests are controlled by pathogens, insects, and grazing animals.

Types Of Biocontrol Agents
Natural biocontrol can be done with the use of two main two methods. Inundative Biocontrol uses pathogens. This method uses pathogens helping control the development of weeds and is as efficient as herbicides. Nematodes and nuts are used in inundative biocontrol and avert invasive plants from implementation. Classical Biocontrol is alternative process helping in organic pest control. This method uses the usual prey-predator relationship. In this method, a relationship is shaped between plants and biocontrol animals.
Different Biological Control Agents
Some of the examples of biological control agents are as follows:
Fungi
Fungus, forms an organic pest control method. Fungi are measured a quickly emerging method and don’t harm the environment. Fungi have proved to be a effective alternative to chemical pesticides. This biocontrol agent is gaining a lot of popularity of late. Entomophaga is a fungus effective against green peach aphids forming an organic pest control method.
Predators
Predators are free-living organisms consuming other animals in a large number in their lives. Seeing insects are majorly consumed crops, the perfect predators to act as a biotic method of pest control are dragonflies, spiders, lacewings, etc.
Bacteria
The coccobacillus bacteria are reasonably more infective to insects and henceforth used for biocontrol. The bacteria contaminate the digestive tracts of the insect limiting the options for insects having sucking mouthparts. Bacteria is an effective method of biocontrol.
Virus
The formation of a virus selectively targeting pests and act as biocontrol is still undergoing research. These viruses would be precise with regards to their hosts and would henceforth be efficient biocontrol agents.
Parasitoids
The parasitoids lay eggs in their host’s body ultimately leading to the host’s death. The dead host is at that moment used by the larvae as a source of food as is one of the most predominant approaches of biocontrol.
Advantages Of Biological Control
The compensations of biocontrol ecology and applications are more than a few. The biocontrol agents are environment- friendly and don’t have any side effects for people. These approaches are also reasonably inexpensive than other pesticides and insecticides. These approaches are likewise easily usable, readily obtainable, and can be used through the year. The most vital use of biocontrol agents is possibly helping in reducing the usage of chemicals and pesticides having damaging effects for humans.
Because of the strict regulations of the government regarding chemical pesticides, the demand for biocontrol agents is on the rise, and the total value will reach above $13,634 million at a growth rate of above 12% in the years to come.
