Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides often require high doses to effectively control weeds and may not provide a broad spectrum of activity, leading to potential crop damage.
Innovation Solution
A herbicidal composition combining rimisoxafen with a Group 15 herbicide and an HPPD inhibitor, which can exhibit synergistic effects, allowing for lower doses and increased efficacy against various weed species while minimizing crop damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high doses of existing herbicides are used, then weed control effectiveness is improved, but crop damage risk increases and herbicide usage quantity increases
Solution Approach 1:
The patent combines rimisoxafen with Group 15 herbicides and HPPD inhibitors to create a multi-component herbicidal composition. This merging of different herbicide classes with distinct modes of action achieves synergistic effects, allowing effective weed control at lower application rates while reducing crop damage risk through the complementary mechanisms of action.
Solution Approach 2:
The invention creates a composite herbicidal formulation integrating three different herbicide types (rimisoxafen, Group 15 herbicides, and HPPD inhibitors). This composite approach leverages the unique properties of each component to achieve enhanced efficacy and safety profile that cannot be obtained with single herbicides alone.
2Reliability
If high doses of existing herbicides are used, then weed control effectiveness is improved, but herbicide usage quantity increases
Solution Approach 1:
By merging rimisoxafen with Group 15 herbicides and HPPD inhibitors in a single composition, the patent achieves synergistic herbicidal activity that allows effective weed control at lower total application rates compared to using individual herbicides at high doses.
Solution Approach 2:
The invention changes the concentration parameters of individual herbicide components by utilizing their synergistic interactions. The composition enables each component to be applied at optimized, lower concentrations while maintaining or enhancing overall weed control effectiveness through the combined action of all three herbicide types.
3Adaptability or versatility
If single herbicides are used, then application simplicity is maintained, but spectrum of activity is limited
Solution Approach 1:
The patent merges three different herbicide classes with distinct modes of action into a single integrated composition. This combination expands the spectrum of activity to cover diverse weed species and resistance profiles while maintaining ease of application as a single pre-mixed formulation.
Solution Approach 2:
The herbicidal composition achieves multi-functionality by incorporating herbicides with different modes of action (rimisoxafen, Group 15 herbicides, and HPPD inhibitors), enabling a single application to effectively control a broad spectrum of weed species including those with resistance to individual herbicide classes.
