Role of viruses as a biopesticides
| Aspect | Detail |
| Introduction to Biopesticides | · These are naturally occurring substances derived from living organisms, including viruses. These are used for pest management. |
| Significance of using virus as biopesticides
| · Many biopesticide viruses exhibit high host specificity, targeting only specific pest species. · Viruses used as biopesticides specifically target and infect pest organisms. · Biopesticide viruses infect and replicate within the pest, leading to disease and their mortality. · Biopesticides are generally environment friendly. These are biodegradable and have offer low toxicity to non-target species. · The use of biopesticides reduces the accumulation of chemical residues in the environment and agricultural products. · Viruses used as biopesticides are part of sustainable agriculture practices. It has reduces the dependence on synthetic chemical pesticides. · Some biopesticide viruses create persistent infections in the target pest population thus helps to provide long-term control. |
| Possible role in integrated pest management | · Virus used as biopesticides can be part of integrated pest management (IPM) strategies. · It will help to reduce the development of pest resistance to chemical pesticides. |
