Hello students today will be studying chapter microbes in human welfare in that well be studying topic biocontrol agents when I say about biocontrol agents bio means biology and to control is to basically prevent pest or insects which grow around the crops and destroy the crops a simple example of biocontrol agents dragonflies that kills malaria parasite in this part we’ll be studying about all biocontrol agents. Biocontrol agents that variants biocontrol agents and first one is dragon plants which controls malarial fallacy the second one is bachelors so in Genesis which is present inside BT- cotton or bachelors or in genesis contton whenever caterpillar or larva comes and fields orchids bt cotton this beauty toxin or frou toxin gets inside the body of the organism and the cut of the organism becomes paralyzed due to that throw toxin and eventually that organism or larvae for the caterpillar dies in this process now when bt cotton was made a process for as genetic engineering Western apart from genetically engineered cotton there is bt cotton satchels available or there is bt cotton toxin available which you can take it in package and spray on your firm’s apart from protecting cotton crops Bt toxin helps to product other crops it could be vegetables or some kinds of other materials another kind of bio control agent is trichoderma virus now this trip whatever fungus is a kind of a fungus which could be viral in nature in some cases but basically the white variety that is used is fungal variety that is used to control certain viruses with limit related to tomato another kind of lastly Bakula virus now this back in a virus is broad-spectrum antibiotic or broad-spectrum biofertilizers this baculovirus can kill arthropods insecticides and all other insects but they do not cause any harm to plant body or to any field crops okay it is a kind of by control agent which is used by IPM IPA means integrated pest management when IPM uses it the major causes it does not cause any harm to plants animals or human being all falls into the crop or the field but kills all the unfilled microorganisms viruses and attributes baculovirus are the baile used by control agents so let’s study what biocontrol agents are biocontrol agents bacillus thuringiensis or BT are used to control butterfly or caterpillars but insects feed on bt cotton or bacillus thuringiensis cotton pro toxins causes death of the organism basically vp toxin is engulfed by the organism and this Bt toxin is converted into pro toxin inside the cut of the organism and eventually the organism dies Geronimo’s fungus is used to control certain pathogens basically tricking ama is used to control viruses [Music] vascular viruses they are excellent viruses that attack insects and other arthropods they never caused any harm to plants animals birds or to the crops they only kill certain viruses or arthropods baculovirus is our narrow spectrum by control agents they are viruses which have great affinity towards certain RNA viruses or harmful RNA viruses they never cause any damage to the plants or animals IPM that is integrated pest management of India uses Bakula viruses one large extent to kill harmful organism in this part of the chapter we studied about biocontrol agents like bt cotton tricking oma and battle of viruses and what is their effect on plants humans and how do they help plants in better way and are beneficial as compared to any other chemical means I hope you all have understood about biocontrol agents and their functions thank you
