Aminopyralid and Oxyacetamide Synergistic Herbicidal Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicidal compositions, particularly those containing aminopyralid, often fail to provide sufficient control of harmful plants and can damage crop plants, necessitating higher application rates and reduced efficacy against weeds like Alopecurus myosuroides, Apera spica-venti, and others, while also lacking pre-emergence activity.
Innovation Solution
A herbicidal composition combining aminopyralid with oxyacetamides like flufenacet and chloroacetanilides such as dimethenamid, metazachlor, or metolachlor, in specific weight ratios from 100:1 to 1:100, enhancing herbicidal activity through synergism and improving crop compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aminopyralid is applied at higher rates to improve control of harmful plants, then herbicidal activity is enhanced, but crop plant damage increases
Solution Approach 1:
The patent combines aminopyralid with oxyacetamides and/or chloroacetanilides in specific formulations to achieve synergistic herbicidal activity. This merging of different herbicide modes of action allows for enhanced weed control at lower application rates, thereby reducing crop damage while maintaining reliability of harmful plant control.
Solution Approach 2:
The invention creates composite herbicidal compositions containing aminopyralid in combination with oxyacetamides and/or chloroacetanilides. These composite materials leverage the complementary properties of different herbicide classes to achieve both effective weed control and crop safety, resolving the contradiction between control reliability and crop protection.
2Object-affected harmful factors
If aminopyralid application rates are lowered to reduce crop damage, then crop compatibility is improved, but control of harmful plants becomes insufficient
Solution Approach 1:
By merging aminopyralid with oxyacetamides and/or chloroacetanilides in formulated compositions, the patent achieves synergistic effects that provide sufficient herbicidal activity at reduced application rates. This allows improved crop compatibility while maintaining reliable control of harmful plants through the combined action of multiple herbicide modes of action.
Solution Approach 2:
The invention changes the concentration parameters of herbicidal active substances by using lower application rates of formulated compositions containing aminopyralid combined with oxyacetamides and/or chloroacetanilides. This parameter change enables reduced crop damage while maintaining effective weed control through synergistic interactions.
3Device complexity
If single herbicide applications are used to simplify treatment, then application complexity is reduced, but pre-emergence activity is insufficient
Solution Approach 1:
The patent merges aminopyralid with oxyacetamides and/or chloroacetanilides in single formulated compositions that provide both pre-emergence and post-emergence herbicidal activity. This combining of multiple herbicide modes of action in one product delivers comprehensive weed control across different emergence stages without requiring separate application treatments.
Solution Approach 2:
The formulated compositions containing aminopyralid combined with oxyacetamides and/or chloroacetanilides achieve multi-functionality by providing both pre-emergence and post-emergence herbicidal activity in a single application. This universal solution simplifies treatment programs while maintaining reliable weed control throughout the crop cycle.
