Herbicidal Composition Synergy Isoxazoline Derivative
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides lack satisfactory selectivity between crops and weeds, requiring higher doses and narrower herbicidal spectra, which limits their effectiveness and safety for specific agricultural applications.
Innovation Solution
A herbicidal composition combining an isoxazoline derivative with specific herbicides from Group A, achieving synergistic effects that broaden the herbicidal spectrum, reduce dosage requirements, and enhance persistence, while maintaining safety for targeted crops like rice, wheat, and corn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single herbicide is used, then the herbicidal effect is achieved, but the herbicidal spectrum is narrow and selectivity between crops and weeds is insufficient
Solution Approach 1:
The patent combines an isoxazoline derivative with at least one herbicide from Group A to create a composite herbicidal composition. This merging of two different herbicidal agents broadens the herbicidal spectrum and improves selectivity between crops and weeds, while maintaining manageable composition complexity through systematic formulation approaches.
2Reliability
If a higher dose of herbicide is applied, then the herbicidal effect is enhanced, but the safety to crops decreases and environmental harm increases
Solution Approach 1:
The patent optimizes the dosage parameters by combining isoxazoline derivatives with Group A herbicides in specific ratios. This parameter optimization achieves satisfactory herbicidal effects at lower doses compared to single herbicide applications, thereby improving crop safety and reducing environmental harm while maintaining reliable weed control.
3Duration of action of moving object
If a single herbicide application is made, then the application process is simple, but the herbicidal effect duration is short
Solution Approach 1:
The patent merges isoxazoline derivatives with Group A herbicides in a single composite formulation, achieving extended herbicidal effect duration through synergistic interactions. This approach provides long-lasting weed control in a single application, avoiding the need for multiple treatments while maintaining simple application processes.
