Azole Fungicide Composition With Additives to Reduce Phytotoxicity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Azole fungicides face issues of phytotoxicity and formulation challenges when used in combination with other pesticides, and copper-based fungicides are limited by phytotoxicity and toxicity, necessitating a composition that enhances their efficacy and safety.
Innovation Solution
A combination of azole fungicides with additives such as thiourea-based compounds, sodium thiosulfate, or alkyl amines is used to reduce phytotoxicity and improve plant health, formulated as a composition that includes steps like preparing an aqueous mixture with these additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If azole fungicide is applied to control fungal pathogens, then fungicidal efficacy is improved, but phytotoxicity to susceptible crops increases
Solution Approach 1:
The patent introduces copper-based fungicide as an intermediary substance that works synergistically with azole fungicide. The copper component (e.g., copper hydroxide, copper oxychloride) provides alternative mode of action against fungal pathogens while the azole component maintains its fungicidal activity. This combination allows reduced application rates of azole fungicide, thereby reducing phytotoxicity while maintaining or improving overall fungicidal efficacy.
Solution Approach 2:
The patent creates a composite fungicidal composition combining azole fungicide with copper-based fungicide components. This composite formulation leverages the complementary properties of both substances: the systemic action of azole fungicides and the contact action of copper-based fungicides. The composite material achieves enhanced broad-spectrum activity while allowing lower doses of the more phytotoxic azole component.
2Reliability
If copper-based fungicide is used to control pathogens, then broad-spectrum efficacy is improved, but toxicity to user and phytotoxicity to plant increase
Solution Approach 1:
The patent merges copper-based fungicide with azole fungicide in a single composition. This combination allows the copper component to provide broad-spectrum contact protection while the azole component provides systemic protection. The synergistic interaction between the two substances enables reduced application rates of copper-based fungicide, thereby reducing user toxicity and phytotoxicity while maintaining broad-spectrum efficacy.
3Adaptability or versatility
If azole fungicide is formulated in presence of other pesticides, then pest control versatility is improved, but formulation complexity increases
Solution Approach 1:
The patent creates a universal composition that combines azole fungicide with copper-based fungicide, providing multi-functional protection against a broad spectrum of fungal pathogens. This single formulation can replace multiple separate pesticide applications, simplifying the overall pest management program while maintaining versatility. The composition is designed to be stable and compatible, avoiding complex formulation challenges.
