Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fungicide compositions, including combinations of dithiocarbamate and benzimidazole fungicides, often lack synergistic effectiveness in granular formulations, leading to reduced phytotoxicity and stability, and are not economically significant in controlling fungal diseases effectively.
Innovation Solution
A solid fungicidal composition comprising a dithiocarbamate fungicide, such as mancozeb, combined with a benzimidazole fungicide or copper fungicide, in a synergistic ratio, specifically formulated for direct use as a water dispersible granular formulation to enhance fungal control and plant vigor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dithiocarbamate and benzimidazole fungicides are combined in granular formulations, then fungal control coverage is improved, but synergistic effectiveness is reduced
Solution Approach 1:
The patent changes the physical state parameter from granular to soluble formulation, and optimizes the concentration ratio parameter of dithiocarbamate to benzimidazole fungicides to achieve synergistic effectiveness. This resolves the contradiction by finding the right formulation parameters that enable both broad coverage and strong synergy.
Solution Approach 2:
The patent creates a composite fungicide composition combining dithiocarbamate and benzimidazole fungicides in specific ratios within a soluble formulation framework. This composite approach allows the two different chemical classes to work together synergistically while maintaining solubility and effectiveness.
2Reliability
If fungicide application rate is increased, then fungal control effectiveness is improved, but economic significance is reduced
Solution Approach 1:
The patent optimizes the concentration ratio parameter of the fungicide components to achieve synergistic effects at lower application rates. The soluble formulation also improves delivery efficiency, allowing effective fungal control with reduced material input, thus maintaining economic viability.
Solution Approach 2:
The patent develops a cost-effective soluble formulation that can be applied at lower rates while maintaining effectiveness. This approach uses economical formulation methods and ratios that reduce overall treatment costs while achieving reliable fungal control.
3Ease of operation
If granular formulation is used, then ease of application is improved, but stability and phytotoxicity are reduced
Solution Approach 1:
The patent changes the formulation state from granular to soluble, which improves stability and reduces phytotoxicity. The soluble formulation allows better control of active ingredient release and interaction, enhancing compositional stability while maintaining ease of application through liquid or dissolved forms.
