Fermented Composition for Plant Growth Suppressing Bacterial Wilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling bacterial wilt disease, such as grafting, are time-consuming, costly, and difficult to implement, and may affect the taste of crops, while existing inhibitors face challenges in effectively suppressing the disease without impacting plant health.
Innovation Solution
A plant vitality adjuvant containing a fermented composition made from a variety of fruits, roots, grains, beans, seaweeds, and saccharides, which acts as a transcription inhibitor for specific genes in Ralstonia solanacearum, suppressing bacterial wilt disease without affecting crop taste or requiring complex handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grafting to resistant cultivar is used to control bacterial wilt disease, then disease resistance is improved, but time consumption, labor effort, and cost increase
Solution Approach 1:
The invention extracts the disease resistance function from the complex grafting process by isolating the active components (polyphenols, organic acids, enzymes) from the rootstock material and applying them directly as a treatment solution, eliminating the need for time-consuming grafting procedures while maintaining disease resistance
Solution Approach 2:
The invention uses an intermediate substance (fermented extract containing bioactive compounds) to transfer the disease resistance property from rootstock to scion, avoiding direct grafting while achieving the same protective effect through chemical mediation
2Reliability
If grafting is used to control bacterial wilt disease, then disease resistance is improved, but operational complexity and cost increase
Solution Approach 1:
The invention extracts the disease resistance function from the complex grafting process by isolating the active components (polyphenols, organic acids, enzymes) from the rootstock material and applying them directly as a treatment solution, eliminating the need for time-consuming grafting procedures while maintaining disease resistance
Solution Approach 2:
The invention replaces the permanent, complex grafting structure with a simple, disposable fermented extract treatment that can be easily applied and discarded, reducing operational complexity and cost
3Reliability
If conventional inhibitors containing Tepidibacter bacteria are used, then bacterial wilt disease is suppressed, but handling difficulty and potential impact on crop taste occur
Solution Approach 1:
The invention replaces the biological system (live Tepidibacter bacteria) with a chemical system (fermented extract containing stable bioactive compounds), eliminating handling difficulties associated with live microbial preparations while maintaining disease suppression efficacy
Solution Approach 2:
The invention changes the state of the active ingredients from live bacterial cells to stable fermented extract compounds, altering physical and chemical parameters to improve handling ease while preserving biological activity for disease suppression
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fermented composition significantly suppresses bacterial wilt disease by inhibiting the expression of pathogenicity-related genes in Ralstonia solanacearum, providing a cost-effective and taste-neutral solution for crop protection, demonstrated through concentration-dependent and pH-adjusted efficacy tests.
Implementation Method 1
a fermented composition obtained by fermenting and aging one or more fruits selected from apples, persimmons, bananas, pineapples
