Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pesticidal methods are used to control invertebrate pests and nematodes, then pest control effectiveness is achieved, but pesticide resistance is induced and toxicity increases
Solution Approach 1:
The patent combines Bacillus amyloliquefaciens (a beneficial bacterium) with cis-jasmone (a natural organic compound) to create a synergistic pesticidal mixture. This combination achieves enhanced pest control effectiveness while reducing reliance on synthetic pesticides, thereby minimizing resistance induction and toxicity. The synergistic interaction between the bacterial components and cis-jasmone allows for reduced application rates while maintaining or improving control efficacy.
Solution Approach 2:
The invention changes the chemical and biological parameters of pest control by using a bio-based approach instead of conventional synthetic pesticides. The mixture leverages the metabolic products of Bacillus amyloliquefaciens combined with cis-jasmone to achieve pest control through different mechanisms (biological and chemical synergy), thereby avoiding the harmful effects associated with traditional high-toxicity pesticides.
2Reliability
If high application rates of pesticides are used to ensure pest control, then pest control effectiveness is improved, but toxicity and applicator safety worsen
Solution Approach 1:
The synergistic combination of Bacillus amyloliquefaciens and cis-jasmone allows for reduced application rates while maintaining effective pest control. The synergistic interaction means that the combined effect exceeds the sum of individual components, enabling lower doses to achieve the same or better control effectiveness, thereby reducing toxicity and improving applicator safety.
Solution Approach 2:
The invention uses naturally occurring and rapidly degradable components (beneficial bacteria and organic compounds) that break down quickly in the environment. This reduces persistence and accumulation, allowing for safer application rates without long-term toxic effects, thereby improving applicator safety and reducing environmental harm.
3Adaptability or versatility
If broad-spectrum pesticides are used to combat multiple pests, then application range is improved, but resistance induction and toxicity increase
Solution Approach 1:
The patent creates a multi-component system combining Bacillus amyloliquefaciens (which produces multiple antimicrobial substances including lipopeptides and surfactins) with cis-jasmone. This combination targets multiple physiological pathways in pests through different mechanisms of action, providing broad-spectrum control while reducing resistance induction because pests cannot easily develop resistance to multiple simultaneous attack mechanisms.
Solution Approach 2:
The pesticidal mixture exhibits multi-functionality by controlling various types of pests (invertebrates, nematodes, fungal pathogens) through different active components. The Bacillus amyloliquefaciens strain produces multiple bioactive compounds, and cis-jasmone adds additional modes of action, creating a universal solution that addresses diverse pest problems without relying on a single high-toxicity chemical.
4Reliability
If synthetic pesticides are used to protect plant propagation material, then pest protection is achieved, but environmental persistence and toxicity worsen
Solution Approach 1:
The invention employs naturally occurring, rapidly degradable components including beneficial bacteria and organic compounds. Bacillus amyloliquefaciens and cis-jasmone break down quickly in the environment through natural metabolic processes, providing short-term protective action without long-term persistence. This reduces environmental contamination while maintaining effective plant protection during critical early growth stages.
Solution Approach 2:
The Bacillus amyloliquefaciens strain is a living organism that can self-replicate and continue producing antimicrobial substances in situ on or near the plant. This self-service capability provides ongoing protection without requiring persistent chemical residues, as the bacteria actively maintain protective levels of antimicrobial compounds throughout the plant's development.
