Natural chemo-sensitizing agents as fungicide potentiators
This solution leverages natural chemo-sensitizing agents to enhance fungicide efficacy by disrupting fungal defense systems. By repurposing natural compounds, it reduces fungicide dosage, lowers costs, and minimizes side effects, improving pathogen control in agriculture.
Overview
This innovative approach utilizes natural chemo-sensitizing agents to act as fungicide potentiators, enhancing the efficacy of conventional fungicides. By targeting the cellular defense systems of fungal pathogens, these natural compounds disrupt redox homeostasis, which weakens the pathogen's ability to resist antifungal treatments. The repurposing of natural medicinal compounds aims to significantly lower fungicide dosages, reducing costs and minimizing potential side effects on crops and the environment.
Technical specifications
- Chemo-sensitization: The process involves using natural compounds that, while not highly potent antifungals themselves, enhance the effectiveness of existing fungicides.
- Compound Library Screening: A systematic screening of natural medicinal compounds to identify those that act as effective potentiators when used with fungicides like triazole, strobilurin, carboxamide, and phenylamide.
- Evaluation Methods: Includes checkerboard assays and seed testing to assess the reduction in minimum inhibitory concentrations and to evaluate the impact on seed germination and fungal growth inhibition.
- Implementation: Provides selected compounds for large-scale deployment, along with technical guidance and customer support.
Technology readiness level
This solution has achieved a Technology Readiness Level (TRL) of 5, indicating that it has been validated in a relevant environment and is moving towards broader application and deployment.
