Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fludioxonil formulations face issues with dustiness during handling and inadequate retention properties, particularly in high loading applications, and lack satisfactory sprayable conditions.
Innovation Solution
An aqueous composition comprising at least 10% fludioxonil, polyoxyalkylene copolymers with a molecular weight up to 4000 g/mol, dispersing agents, and water, which improves retention properties and ensures low viscosity for easy handling and sprayable conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If solid-state formulation (water dispersible granules) is used, then high loading of fludioxonil is achieved, but dust issues occur and handling becomes difficult
Solution Approach 1:
The patent changes the physical state parameter from solid (granules) to liquid (aqueous composition), eliminating dust issues while maintaining high fludioxonil loading (at least 10% by weight). This phase transition resolves the contradiction between achieving high loading and ensuring ease of handling.
2Quantity of substance
If solid-state formulation is used, then high loading of fludioxonil is achieved, but retention properties are insufficient
Solution Approach 1:
The patent uses a composite aqueous composition containing fludioxonil combined with specific surfactants and adjuvants. This composite formulation achieves both high fludioxonil loading (at least 10% by weight) and improved retention properties through the synergistic effects of the multiple components, resolving the contradiction between loading and retention.
3Quantity of substance
If high loading of fludioxonil is achieved, then effective fungicidal activity is obtained, but viscosity increases and sprayability deteriorates
Solution Approach 1:
The patent introduces surfactants and viscosity modifiers as intermediary substances that enable high fludioxonil loading (at least 10% by weight) while maintaining acceptable viscosity and sprayability. These intermediaries mediate between the active ingredient and the formulation vehicle, resolving the contradiction between loading and sprayability.
4Ease of operation
If aqueous formulation is used, then handling and sprayability are improved, but retention properties may be insufficient without specific additives
Solution Approach 1:
The patent employs multifunctional surfactants and adjuvants that simultaneously improve handling properties and retention properties. These universal additives perform multiple functions: they enhance sprayability while also improving retention, eliminating the need to trade off between handling and retention performance.
