Biocontrol Methods
Biocontrol is a method of scheming or calculating or managing plant pests and diseases without using the chemicals or the chemical components, and by employing predators and parasites which nourish or feed upon them.
Bio-control is commonly known as biological control, in which the pests, infection, or diseases are controlled, by disturbing the environmental or biological position, by using the natural organisms like, the parasites, or pathogens, herbivory, natural predators, or various other natural mechanisms, etc. The natural enemies are used to reduce or diminish the harm or damage caused by the pest inhabitants or population. These methods are used to control pests like the weeds, mites, insects plant diseases, etc.
Biological control of pests and diseases are the most essential component of the integrated pest management. The biological control method reunites persistent plants with their enemies, to re-establish natural reins and decrease the dominance of invasive vegetation, inside the plant community. Thus, they are promoted as a self-supporting, self-dispersing control technique as bio-control is frequently used to steadily repress extensive infestations.
Various bio-control methods:
- Classical Biological Control Method: The classical biological control involves or immerses, releasing any foreign or rare organism that implants or decree itself and spreads enduringly and permanently to control a pest. It is a prologue of natural enemies, to the fresh and original surroundings, which do not occur originally. It is defined as, by means of a single organism the other organism can be controlled, and can be used to re-establish few of the adaptable or changeable factors, that shortens the aggressive capability of a pest. Very often, these introduced pests are referred to as exotic pests as new-fangled types of insects are continuously arriving, unintentionally or intentionally. Usually from time to time, they do survive and when they arrive, their enemies are missing or left. It is more often than not, most effectual against exotic pests and are hardly so against native insect pests. The technique is everlasting and economical.
- Augmentation Method: The augmentation method is another type or kind of biological control or biocontrol method. In this technique, supplemental discharge of natural enemies is implicated. This method seasonally controls the pests, by introducing the natural enemies. The pest predators are not enduringly, recognized and established in the surrounding or environment. Instead of that, these pests are yearly introduced to manage and control the seasonal pests. The augmentation method is also known as inundative technique. In this process, there is a mass introduction of a vast parasite or predators for controlling and destroying the pests. The useful and necessary insects are used as a beneficial pesticide. The technique is long-lasting and economical.
- Conservation Method: The conservation is a technique of biological control for insects that attempts to preserve or protect the pest type natural enemies. Numerous times, this technique employs the decline of pesticides that might be decimating the pest's natural enemies, or a control to pesticides, which may have a slighter result on the predators. In addition, preservation involves rising or growing of some plants that sustain the pest enemies. This move or approach is an amalgamation of shielding biocontrol agents and providing assets or resources so that they can be more effectual.
