What is biological control of disease?
Biological control is the control of disease by the application of biological agents to a host animal or plant that prevents the development of disease by a pathogen. Viruses can also be used as biocontrol agents and there is a resurgent interest in the use of bacterial viruses for control of plant diseases.
What are examples of biological control?
Biological control exampleAn example of biological control is the release of parasitic wasps to control aphids. Aphids are a pest of plants and cause huge damage to plants as they remove nutrients from the plant. The parasitic wasp lays eggs in aphids, as shown in the movie.
Which is used as a biocontrol agent in the treatment of plant disease?
The most commonly targeted pathogens are Pythium, Fusarium, and Rhizoctonia species, reflecting their worldwide importance and relative ease of control (Whipps, 2001). The most commercially successful bacterial-based biocontrol system is the use of the nonpathogenic Agrobacterium strains to control crown gall.
Which of the following fungi is found useful in the biological control of plant disease?
Trichoderma viridae is used as a biocontrol agent against various types of fungi.
What are the advantages of biological control?
Advantages of Biological Control:Natural enemies introduced to the environment are capable of sustaining themselves, often by reducing whatever pest population they are supposed to manage. This means that after the initial introduction, very little effort is required to keep the system running fluidly.
What are the 3 methods of pest control?
As mentioned above, there are many pest control methods available to choose from, but they can be loosely grouped into six categories: Hygienic, Biological, Chemical, Physical, Fumigation, Fogging and Heat treatment.
Why is biological control used?
Biological control, the use of living organisms to control pests. A natural enemy such as a parasite, predator, or disease organism is introduced into the environment of a pest or, if already present, is encouraged to multiply and become more effective in reducing the number of pest organisms.
What is biological method?
The biological method refers to bioremediation, in which biological processes (microorganisms) are used to degrade and metabolize chemical substances and restore environment quality.
What is biological control of population growth?
Population control may involve culling, translocation, or manipulation of the reproductive capability. The growth of a population may be limited by environmental factors such as food supply or predation. The less food, the less fertile a species of reproductive age becomes.
