Herbicidal Combinations Synergistic Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides often require high application rates to maintain effectiveness, leading to increased economic and ecological costs, and may suffer from stability issues and antagonistic effects when combined, limiting their ability to control a broad spectrum of weeds efficiently.
Innovation Solution
A composition combining herbicidally active compounds (A) and (B), where (A) includes 3-phenylisoxazoline-5-carboxamides or their agrochemically compatible salts, and (B) comprises specific herbicides from groups like 1,3-diketo compounds, (sulfone)amides, aryl nitriles, and others, which work synergistically to enhance weed control while reducing application rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application rate of herbicides is increased to maintain effectiveness, then herbicidal efficacy is improved, but economic and ecological costs increase
Solution Approach 1:
The patent combines multiple herbicides with different modes of action into a single formulation. This merging allows the herbicide mixture to achieve superior weed control efficacy at lower individual application rates compared to using a single herbicide, thereby reducing both economic and ecological costs while maintaining reliability in weed management.
Solution Approach 2:
The invention creates a composite herbicide product containing multiple active ingredients with complementary mechanisms of action. This composite approach enables synergistic effects that enhance weed control effectiveness, allowing reduced application rates while maintaining or improving herbicidal performance, thus addressing both efficacy and cost concerns.
2Adaptability or versatility
If multiple herbicides are combined to improve application profile, then weed control spectrum is expanded, but stability and compatibility issues occur
Solution Approach 1:
The patent carefully selects and formulates specific herbicide combinations where the chemical and physical parameters of the mixture are optimized to ensure stability. By adjusting formulation conditions and selecting compatible herbicide pairs, the invention achieves broad weed control spectrum while maintaining formulation stability and preventing degradation or antagonistic effects.
3Reliability
If herbicide application rate is increased to compensate for loss of efficacy, then control effectiveness is maintained, but selectivity is reduced
Solution Approach 1:
The invention segments the herbicide action into multiple mechanisms of action, with each herbicide component targeting specific weed types or physiological processes. This segmentation allows the formulation to maintain control effectiveness against diverse weeds while preserving selectivity, as each component can be optimized for specific targets rather than relying on high doses that would reduce selectivity.
