Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods are inadequate for effectively controlling plant pests and improving agronomic traits in plants, as they often result in significant agricultural losses and do not provide comprehensive solutions for pest management and trait enhancement.
Innovation Solution
Utilizing bacterial strains, such as Pseudomonas chlororaphis strain AIP059286, and their variants, which are formulated into various compositions to control plant pests and enhance agronomic traits through formulations like cell pastes, wettable powders, and granules, while being resistant to biocides and maintaining pesticidal activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical pesticides are used to control plant pests, then pest control effectiveness is improved, but environmental pollution and harmful effects on non-target organisms increase
Solution Approach 1:
The patent utilizes the pathogenicity of certain bacteria (harmful to pests) to control pest populations, converting the harmful effect of bacterial infection into a beneficial pest control mechanism. The bacteria are selected specifically for their ability to kill or suppress pests while being safer for the environment compared to chemical pesticides.
Solution Approach 2:
The patent introduces beneficial bacteria as intermediary organisms that mediate between the plant and pest interaction. These bacteria colonize the plant surface or interior, creating a biological barrier that prevents pest infestation without directly applying toxic chemicals to the environment.
2Reliability
If chemical pesticides are applied frequently to maintain control, then pest control reliability is improved, but loss of substance and resistance development increase
Solution Approach 1:
The beneficial bacteria establish continuous colonization on the plant surface or interior, providing ongoing protection against pests. This continuous biological presence replaces the need for repeated chemical applications, maintaining pest control reliability while eliminating pesticide residue accumulation.
Solution Approach 2:
The bacteria apply their own mechanism of action (pathogenicity or competition) to control pests, making the system self-sustaining. The bacteria multiply and maintain their population on the plant, providing continuous pest control without requiring external input of chemical pesticides.
3Adaptability or versatility
If broad-spectrum pesticides are used to control multiple pests, then versatility is improved, but harmful effects on non-target organisms and beneficial microbes increase
Solution Approach 1:
The patent employs different bacterial strains with specific pathogenicities or antagonistic properties tailored to target specific pest types. Each bacterial composition is locally optimized for particular pests while being selective and non-harmful to beneficial organisms, replacing the broad-spectrum approach with targeted biological control.
