Fatty Acid and Trichoderma Agrochemical Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agrochemicals, particularly synthetic small molecule fungicides, are ineffective in controlling fungi and oomycetes while posing environmental risks and harming non-target species, necessitating the development of environmentally friendly alternatives with high efficacy.
Innovation Solution
A combination of fatty acids and derivatives with species of fungus or oomycete, such as Trichoderma, which inhibits the growth or kills plant pathogens, providing an effective agrochemical composition for controlling fungi, oomycetes, and promoting plant growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic small molecule fungicides are used to control fungal infections, then fungal control efficacy is improved, but environmental safety and harm to non-target species deteriorates
Solution Approach 1:
The patent combines fatty acids with fungal species or their metabolites to create a composite agrochemical composition. This composite approach leverages the antifungal properties of both components while maintaining environmental safety, as natural fatty acids and fungal metabolites replace harmful synthetic chemicals.
Solution Approach 2:
The patent changes the chemical composition parameters by using naturally occurring fatty acids and fungal metabolites instead of synthetic small molecules. This parameter change maintains antifungal efficacy while improving environmental compatibility and reducing harm to non-target species.
2Object-affected harmful factors
If naturally occurring substances like oils and fatty acids are used as fungicides, then environmental safety is improved, but antifungal efficacy deteriorates
Solution Approach 1:
The patent merges fatty acids with fungal species or their metabolites in a combined composition. This merging creates a synergistic effect where the natural substances work together to enhance antifungal efficacy while maintaining environmental safety, overcoming the limitation of using natural substances alone.
Solution Approach 2:
By creating a composite formulation of fatty acids and fungal components, the patent achieves high antifungal efficacy through the combined action of multiple natural substances, thereby improving upon the limited efficacy of single natural antifungal agents.
3Object-affected harmful factors
If fungal species are used alone as fungicides, then environmental safety is improved, but antifungal efficacy is insufficient
Solution Approach 1:
The patent combines fungal species or their metabolites with fatty acids to create a more effective composition. This combination enhances the antifungal efficacy of the fungal component while maintaining the environmental safety benefits of using natural biological agents.
