Aqueous Glufosinate-Auxin Herbicide Composition With Lower Viscosity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicide compositions with high concentrations of water-soluble salts of glufosinate and synthetic auxin herbicides, such as 2,4-D and dicamba, suffer from incompatibility issues and unacceptably high viscosity, making them difficult to handle and apply with conventional agricultural equipment.
Innovation Solution
Aqueous herbicide compositions containing a water-soluble salt of glufosinate and a synthetic auxin herbicide, along with a surfactant, exhibit reduced viscosity, improving handling and application by incorporating specific organic amine or quaternary ammonium cations for neutralization, resulting in a 40% to 90% reduction in viscosity at room temperature and 50% to 80% reduction at 0°C compared to compositions without the synthetic auxin herbicide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high concentrations of water-soluble salts of glufosinate and synthetic auxin herbicides are used, then herbicidal efficacy is improved, but viscosity becomes unacceptably high
Solution Approach 1:
The patent applies parameter changes by modifying the physical state and concentration parameters of the herbicide composition. Specifically, it formulates the composition to maintain high concentrations of active ingredients (20-40% glufosinate and 1-10% synthetic auxin) while controlling viscosity through optimized formulation parameters, allowing the composition to remain flowable despite high herbicidal efficacy
Solution Approach 2:
The patent uses composite materials by combining glufosinate and synthetic auxin herbicides in a specific formulation ratio, creating a composite herbicide composition that achieves synergistic efficacy while managing physical properties. The composite nature of the formulation allows high concentrations of both active ingredients to coexist with acceptable viscosity
2Quantity of substance
If high concentrations of water-soluble salts of glufosinate and synthetic auxin herbicides are used, then herbicidal efficacy is improved, but handling difficulty increases
Solution Approach 1:
The patent modifies operational parameters by formulating the composition with specific concentration ranges and physical properties that facilitate handling. The composition is designed to maintain pourability and mixability despite high herbicide concentrations, enabling easy handling during agricultural operations
3Quantity of substance
If high concentrations of water-soluble salts of glufosinate and synthetic auxin herbicides are used, then herbicidal efficacy is improved, but compatibility issues arise
Solution Approach 1:
The patent creates a stable composite formulation by combining glufosinate and synthetic auxin in optimized ratios, ensuring chemical compatibility between the two active ingredients. The formulation maintains stability and prevents incompatibility issues even at high concentrations of both herbicides
