Nanoparticle-enhanced medicinal plant extracts for sustainable pest and pathogen control

Overview

This solution addresses the growing need for sustainable alternatives to synthetic pesticides by converting traditional medicinal plant extracts into nanoparticle formulations. Farmers have long used crude extracts from Citrullus colocynthis (bitter apple) and Calotropis procera (sodom apple) in organic farming practices. This research formalizes that traditional knowledge by applying modern nanotechnology to enhance the efficacy, stability, and delivery of these natural compounds. The resulting formulations are designed to combat fungal pathogens and insect pests that damage crops, offering an environmentally responsible alternative to conventional chemical pesticides.

Technical specifications

Core approach:

• Aqueous extracts from Citrullus colocynthis and Calotropis procera are converted into nanoparticle formulations using carrier materials such as bioclay
• Extracts can be deployed alone or in combination with silver nanoparticles to broaden antimicrobial and pest-repellent activity
• Active ingredients are identified and characterized through metabolomics profiling to isolate the most potent bioactive metabolites
• Nanoparticle delivery is intended to improve compound stability, bioavailability, and targeted action against pests and pathogens

Potential applications:

• Organic and integrated pest management in agriculture
• Control of fungal pathogens affecting crop yields
• Insect pest management with reduced environmental impact
• Sustainable crop protection for regions where these medicinal plants are locally available

Technology readiness level

This research is at an early-to-mid stage of development. The underlying rationale draws on validated farmer practices using herbal extracts in organic agriculture. Planned validation includes metabolomic characterization of active compounds at the International Center for Chemical and Biological Sciences, followed by laboratory and field testing of nanoparticle formulations for antifungal and insecticidal activity. Further studies are needed to confirm efficacy, optimize formulation parameters, and evaluate field-scale performance before commercial deployment.
