Diazine-Amide Insecticide Composition for Resistant Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pesticides are ineffective against certain animal pests, particularly insects and acarines, and there is a need for novel compounds that can effectively control these pests without causing harm to the environment.
Innovation Solution
Development of pesticidally active diazine-amide compounds, including their agrochemically acceptable salts, stereoisomers, and enantiomers, which can be applied to reduce pest populations and prevent further damage to plants and plant-derived products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pesticides are used, then pest control is attempted, but they are ineffective against certain animal pests particularly insects and acarines
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure to create diazine-amide compounds with specific molecular characteristics. The general formula I structure with varied substituents (R1-R5b, A1) represents systematic parameter changes in molecular weight, functional groups, and structural configuration to achieve enhanced effectiveness against previously resistant pest species.
Solution Approach 2:
The invention employs composite material principles by creating hybrid chemical structures that combine diazine rings with amide functional groups and various substituent combinations. This composite molecular architecture integrates multiple chemical moieties (heterocyclic rings, carbonyl groups, alkyl/alkenyl/alkynyl substituents) to produce synergistic effects that broaden pest control spectrum and overcome resistance to conventional single-function pesticides.
2Reliability
If novel pesticidally active compounds are developed, then effectiveness against resistant pests is improved, but environmental safety must be maintained
Solution Approach 1:
The patent applies local quality by incorporating specific functional groups and substituents at particular positions within the diazine-amide molecular framework. The selective placement of electron-withdrawing or electron-donating groups (such as halogens, alkyl groups, or heteroatoms at specific R positions) creates localized regions of different chemical reactivity and binding affinity, enabling targeted pest control while reducing non-specific environmental interactions.
3Adaptability or versatility
If compounds with multiple substituents are designed, then pest control spectrum is broadened, but molecular complexity increases
Solution Approach 1:
The patent implements universality by designing the diazine-amide core structure (formula I) as a multi-functional platform that can accommodate various substituent types (R1-R5b) while maintaining a consistent fundamental architecture. This universal scaffold allows a single molecular framework to interact with multiple pest target sites and physiological pathways, providing broad-spectrum activity without requiring entirely different molecular structures for each pest type.
