Herbicidal Composition Synergy for Rice Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicidal compositions often lack effective control over grasses and weeds in crops, particularly in rice crops, and may have limited crop tolerance and require higher doses of individual herbicides when used alone.
Innovation Solution
A novel herbicidal composition comprising compounds of formulas (I) and (II), or their agrochemically acceptable salts, applied in specific ratios and formulations, which can be used to inhibit plant growth and control weeds, potentially exhibiting synergistic effects and increased crop tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher doses of individual herbicides are used alone, then herbicidal activity is improved, but crop tolerance deteriorates and harmful factors increase
Solution Approach 1:
The patent combines two different herbicidal compounds (formula I and formula II) into a single composition, where each compound targets different weed pathways. This synergistic combination allows effective weed control at lower total doses, reducing crop stress while maintaining or improving herbicidal activity compared to single herbicide applications.
2Ease of operation
If single herbicide compositions are used, then application simplicity is improved, but effectiveness against diverse weeds deteriorates
Solution Approach 1:
The herbicidal composition incorporates two compounds with different modes of action that together provide broad-spectrum weed control covering grasses, sedges, and broadleaf weeds. This multi-functional approach enables a single application to address diverse weed types that would otherwise require multiple separate herbicide applications.
