Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pesticidal agents face challenges due to the development of resistance by invertebrate pests such as insects, arachnids, and nematodes, necessitating the need for new compounds with broad-spectrum activity.
Innovation Solution
Development of substituted imidazolium compounds with specific structural formulas that include various functional groups, which are effective against a wide range of invertebrate pests, including difficult-to-control insects and arachnids, in agricultural and veterinary applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pesticidal agents are used, then initial pest control is effective, but pests develop resistance over time reducing efficacy
Solution Approach 1:
The patent employs parameter changes by modifying the chemical structure of pesticidal compounds through various substituents (R1, R2, R3, R4, R5 groups) on the imidazolium core structure. This structural diversification creates new chemical entities with altered biological properties, enabling effective pest control while overcoming resistance developed to previous generations of pesticides.
2Adaptability or versatility
If broad-spectrum pesticidal activity is achieved, then control against multiple pest types is improved, but selectivity and potential non-target effects may worsen
Solution Approach 1:
The patent applies local quality by incorporating specific functional groups and substituents at particular positions on the imidazolium ring structure. Each substituent (R1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, C3-C10 cycloalkyl, etc.) is positioned to optimize interaction with specific pest targets while minimizing effects on non-target organisms, achieving broad-spectrum activity through localized structural features.
