Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compounds with high pesticidal activity and a broad activity spectrum against invertebrate pests, such as insects, arachnids, and nematodes, to address resistance issues and improve efficacy compared to existing pesticides.
Innovation Solution
The development of substituted tricyclic compounds of formula (I) and their agriculturally or veterinarily acceptable salts, stereoisomers, tautomers, or N-oxides, which exhibit high pesticidal activity and a broad activity spectrum against invertebrate pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pesticides are used to combat invertebrate pests, then pest control is achieved, but pest resistance develops and efficacy decreases
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure parameters of pesticidal compounds - specifically transitioning from bicyclic to tricyclic core structures and varying substituent groups (R1-R6, X, Y, Z) to create compounds with enhanced pesticidal activity and broadened activity spectrum against resistant pest populations
Solution Approach 2:
The patent employs composite materials by combining multiple structural elements - a tricyclic core framework with diverse substituent groups including halogens, alkyl chains, aryl groups, and heteroatoms - to create compounds that simultaneously achieve high efficacy and broad-spectrum activity against various invertebrate pests
2Reliability
If application rates are increased to improve efficacy, then pest control effectiveness increases, but environmental impact and costs increase
Solution Approach 1:
The patent utilizes parameter changes by optimizing the chemical structure of tricyclic compounds to achieve higher intrinsic pesticidal activity, which allows for reduced application rates while maintaining or improving efficacy, thereby decreasing environmental load and treatment costs
