Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compounds for controlling plant diseases are not effective in providing comprehensive pest control, leading to inadequate protection against various plant pathogens.
Innovation Solution
A compound represented by formula (I), where R1 is a C1-C3 alkyl group optionally with halogens, n is 1 or 2, R2 and R3 are hydrogen, halogen, or C1-C3 alkyl, R4 is hydrogen or methyl, and R5 is C1-C3 alkyl, alkoxy, or cycloalkyl, is developed for use as an agent to control plant diseases by applying it to plants or soil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing compounds are used for plant disease control, then some level of pest control is achieved, but the efficacy is insufficient for comprehensive protection against various plant pathogens
Solution Approach 1:
The patent employs a composite molecular structure combining a tetrazolinone core with specific substituent groups (aryl, heteroaryl, alkyl, halogen atoms) to create a multi-functional compound that simultaneously exhibits broad-spectrum antifungal, antibacterial, and antiviral activities, resolving the contradiction between reliable disease control and versatility against various pathogens
Solution Approach 2:
The invention introduces specific local modifications to the tetrazolinone molecule by placing particular substituents at defined positions (R1-R6 groups), where each substituent contributes specific functional properties that enhance different aspects of pathogen control, achieving both high efficacy and broad adaptability through localized structural optimization
