Herbicidal Kit Segregating Active Ingredients and Emulsifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for preparing herbicidal application mixtures face challenges in maximizing the loading of active ingredients while controlling offsite movement, particularly due to human error in tank-mixing adjuvants, leading to potential exclusion of offsite movement control agents.
Innovation Solution
A kit comprising two physically separate compositions, Component A and Component B, where Component A is an oily herbicidal composition without emulsifying surfactants and Component B contains offsite movement controlling agents and emulsifying surfactants, ensuring stable emulsification and inclusion of control agents in the application mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tank-mixing of adjuvants and herbicidal concentrates is used, then flexibility in application is improved, but reliability of including offsite movement control agents deteriorates due to human error
Solution Approach 1:
The patent combines the offsite movement control agents with the emulsifying surfactants in a single integrated composition (Component B). This merging ensures that when the user adds Component B to the spray tank, both the emulsification capability and the offsite movement control are simultaneously provided, eliminating the risk of human error in separately mixing multiple adjuvants while maintaining application flexibility.
2Quantity of substance
If high loading of herbicidal actives is achieved, then cost and storage needs are minimized, but control of offsite movement deteriorates due to reduced loading of control agents
Solution Approach 1:
The patent segments the herbicidal composition into two distinct components: Component A containing the herbicidal active ingredients at high concentration, and Component B containing the offsite movement control agents combined with emulsifying surfactants. This segmentation allows Component A to be formulated with maximum active ingredient loading for cost efficiency, while Component B ensures reliable offsite movement control is always included when the components are mixed.
Solution Approach 2:
The emulsifying surfactants in Component B act as intermediaries that enable the combination of oil-based herbicidal concentrates with water-based spray solutions. These surfactants facilitate the incorporation of offsite movement control agents into the final application mixture, ensuring both high active ingredient loading and reliable control of offsite movement are achieved simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for high loading of herbicidal active ingredients with effective control of offsite movement, reducing the risk of agent exclusion and ensuring targeted herbicide application.
Implementation Method 1
Component B is a composition comprising or consisting of constituent b1) one or more offsite movement controlling agents for herbicidal active ingredients, and constituent b2) one or more amphiphilic compounds wherein the hydrophilic-lipophilic balance (HLB) value of the amphiphilic compound or the mixture of amphiphilic compounds is equal to or greater than 6
