N-Oxide Pyridine Amide for Broad Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current amide compounds used for pest control, such as fungicides, lack effectiveness in providing comprehensive pest control solutions.
Innovation Solution
Development of an amide compound with an N-oxide structure, specifically a pyridine ring-based compound, which includes various substituents like fluorine, chlorine, and alkyl groups, offering enhanced pest control efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional amide compounds are used for pest control, then fungicidal activity is provided, but comprehensive pest control effectiveness is insufficient
Solution Approach 1:
The patent modifies the chemical structure of amide compounds by introducing an N-oxide functional group on the pyridine ring and varying substituents (halogens, alkyl groups, etc.) to enhance both fungicidal and insecticidal activities, thereby improving overall pest control effectiveness while expanding the spectrum of control
2Adaptability or versatility
If existing amide compounds are used, then simple chemical structures are maintained, but pest control spectrum is limited
Solution Approach 1:
The patent creates composite chemical structures by combining the pyridine ring, amide group, and N-oxide functional group into a single molecule, integrating multiple functional elements that work synergistically to provide both fungicidal and insecticidal activities within one compound structure
