Microbes are also used in herbicides to control the weed in the field. Other MBCAs act via nutrient competition or other mechanisms modulating the growth conditions for the pathogen. Some MBCAs interact with plants by inducing resistance or priming plants without any direct interaction with the targeted pathogen. The Trichoderma species of Fungi is regarded as a powerful biocontrol agent against several plant pathogens.Trichoderma commonly present in root system of plant and provide strong resistance against the plant Pathogens.Ī genus Nucleopolyhedrovirus under the category of Baculoviruses is used as a biocontrol agent against the various insects and arthropods.They have no any negative impact on plants, mammals ,birds and fish.īaculoviruses are neutral for beneficial insect that are conserved under the programme of Integrated pest management. Microbial biological control agents (MBCAs) are applied to crops for biological control of plant pathogens where they act via a range of modes of action. Several fungi are also used as biocontrol agents to control the pest in the field of Cereals ,fruit and vegetables. In cotton plants, Damping off of seedlings is controlled by the bacteria Pseudomonas. When they feed by the insect, they release a toxin in the gut of the insect, As a result the insect dies.Īgrobacterium radiobacter is used to control the agent that is responsible for crown gall disease in Stone fruits. These bacteria are stored as dried spores and mix with the water to spray on plants. Entomopathogenic fungi as potential biocontrol agents for tsetse flies. This bacteria is used in controlling caterpillars of butterflies. Crit Rev Biotechnol 25:130 Lacey LA, Undeen AH (1986) Microbial control of. Similarly bacteria are also used as Biocontrol agents against the various pests and insects therefore they are known biocides.Ī bacterium Bacillus thuringiensis is capable against insects and pests. In agriculture, Gypsy moths, budworms, and bollworms are controlled by viruses. Various kinds of microbes like viruses, bacteria, fungi, mycoplasma etc are used as biocontrol agents in the field of agriculture. To overcome this problem, methods of biological control are used in present days and therefore may be preferably isolated from the. ganisms would be able to utilize available biochemical resources, Lett Appl Microbiol 28:22632. These chemicals also cause different types of pollution. Ideally, candidate biocontrol or- ified atmosphere stored mungbean sprouts: the use of vegetable-associated bac- teriocinogenic lactic acid bacteria to control growth of Listeria monocytogenes. These chemicals remain present as such in soil and water and affect the biotic component. But these chemicals are toxic and never degraded by our decomposer. Generally, insecticides and pesticides are used to control the pathogen, insect and pest etc. Impact of insecticides, Pesticides on environment. This Article demonstrates the use of Microbes as Biocontrol agents. Term Biocontrol refers to the maintenance of the population of insects and pests by the introduction of their predator and without using any chemicals.
