Abstract
The increasing environmental and health concerns associated with synthetic pesticides have intensified the search for sustainable alternatives in plant disease management. Medicinal plants, rich in bioactive compounds, have emerged as promising biopesticides due to their efficacy, biodegradability, and low toxicity. This paper explores the potential of medicinal plant extracts as biopesticides, highlighting their mechanisms of action, including antimicrobial, antifungal, and insecticidal properties. Previous research has demonstrated the effectiveness of plants like neem (Azadirachta indica), garlic (Allium sativum), turmeric (Curcuma longa), Tulsi (Ocimum sanctum), Aloe Vera (Aloe barbadensis), Ginger (Zingiber officinale) and Eucalyptus (Eucalyptus globulus) in controlling phytopathogens, offering eco-friendly solutions while enhancing crop productivity. The discusses, challenges and opportunities in large-scale adoption, such as standardization, stability, and regulatory approval. By integrating traditional knowledge with modern scientific validation, medicinal plant-based biopesticides can contribute to sustainable agriculture, reducing reliance on harmful chemicals. This study underscores the need for further research to optimize extraction techniques, formulation, and field applications to harness the full potential of medicinal plants in integrated pest management (IPM) systems.
