Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glyphosate formulations are prone to destabilization due to physical or chemical incompatibilities among components, leading to reduced efficacy and uneven application, particularly when mixed with other pesticide formulations under varying field conditions.
Innovation Solution
A herbicidal composition comprising glyphosate, a phosphate ester, and a surfactant component, with specific structures and concentrations, to enhance stability and compatibility, allowing high glyphosate loading and effective application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If glyphosate formulations are mixed with other pesticide formulations, then application versatility is improved, but formulation stability deteriorates due to physical or chemical incompatibilities
Solution Approach 1:
The patent introduces a compatibility agent as an intermediary substance that mediates between glyphosate formulations and other pesticide formulations. This agent prevents direct incompatible interactions between the formulations, allowing them to be mixed without destabilization. The compatibility agent acts as a buffer or protective medium that maintains formulation integrity during tank mixing operations.
Solution Approach 2:
The patent creates a composite formulation system that combines glyphosate, other pesticides, and compatibility agents into a stable mixed formulation. This composite approach allows multiple incompatible substances to coexist by designing a formulation matrix that maintains the stability of each component while enabling their synergistic use in a single application.
2Productivity
If high glyphosate loading is achieved, then productivity is improved, but formulation stability worsens due to increased concentration of active ingredient
Solution Approach 1:
The patent modifies formulation parameters by introducing compatibility agents and adjusting the chemical environment to accommodate high glyphosate concentrations. This allows the formulation to maintain stability even with increased active ingredient loading, enabling both high productivity and formulation stability to coexist.
3Reliability
If formulation components are mixed to enhance efficacy, then herbicidal effectiveness is improved, but compatibility deteriorates leading to flocculation and separation
Solution Approach 1:
The compatibility agent serves as an intermediary that prevents direct incompatible reactions between herbicidal components. It maintains the stability of the formulation while allowing the active ingredients to work synergistically, thus preserving both effectiveness and compatibility.

AI summary
A herbicidal composition includes glyphosate or a derivative thereof, a phosphate ester, and a surfactant component. The phosphate ester is present in an amount of from about 1 to about 15 weight percent actives based on a total weight of the composition. The surfactant component includes at least one of a first surfactant, a second surfactant, and a third surfactant. Each of the first, second, and third surfactants, if utilized, is independently present in an amount of from about 1 to about 15 weight percent actives based on a total weight of the composition.
