Biopesticides are natural compounds that can help manage plant diseases without harming the environment. They offer a better alternative to synthetic pesticides, which can be harmful and lead to pesticide-resistant pests. Biopesticides include natural organisms, biocontrol formulations, essential oils, botanical extracts, and nano biopesticides. They have the potential to reduce the use of synthetic pesticides and their associated costs. However, using biopesticides also comes with challenges like finding effective options, production costs, and assessing risks to animals and humans. Overall, biopesticides are a promising tool for integrated pest management in agriculture.
