Mesoionic Insecticides for Pest Control Efficacy and Toxicity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling invertebrate pests in agronomic and nonagronomic environments are limited by the need for more effective, less toxic, and environmentally safer compounds with different sites of action, as existing products often have limitations in efficacy and safety.
Innovation Solution
Development of substituted mesoionic compounds, their N-oxides, and salts, which are used in compositions as insecticides, including formulations for spray, bait, and seed treatment, to effectively control invertebrate pests by contacting the pests or their environments with biologically effective amounts of these compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing insecticide products are used, then pest control function is provided, but efficacy is limited and toxicity is high
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of insecticide compounds to create new mesoionic compounds with improved efficacy and reduced toxicity. The core invention involves changing molecular parameters (chemical composition, functional groups, substitution patterns) to achieve better pest control while lowering harmful effects on non-target organisms and the environment.
2Reliability
If existing insecticide products are used, then pest control function is provided, but environmental safety is compromised
Solution Approach 1:
The patent modifies chemical parameters of insecticide molecules to develop mesoionic compounds that maintain pest control effectiveness while improving environmental safety. The structural modifications enable selective toxicity toward pests while reducing persistence and harm to beneficial organisms and ecosystems.
3Reliability
If new mesoionic compounds are developed, then efficacy and environmental safety are improved, but compound complexity increases
Solution Approach 1:
The patent applies local quality by introducing specific functional groups and substitution patterns at particular positions within the mesoionic compound structure. This allows optimization of biological activity and environmental properties at specific molecular locations while maintaining the core compound framework, thereby managing complexity through targeted local modifications rather than complete structural redesign.
