Fungicidal Composition Mixture for Broad Spectrum Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fungicidal compositions for controlling phytopathogenic fungi in plants often lack broad spectrum activity, crop tolerance, and efficient application rates, necessitating the development of new compositions with improved biological properties.
Innovation Solution
A fungicidal composition comprising a mixture of cyclic depsipeptides and inhibitors with multi-site action, such as Bordeaux mixture or thio- and dithiocarbamates, in specific weight ratios to enhance efficacy and spectrum of activity against a wider range of fungal pathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single fungicidal compounds or narrow-spectrum compositions are used, then application rates can be reduced, but the spectrum of activity against phytopathogenic fungi is insufficient
Solution Approach 1:
The patent combines multiple fungicidal compounds with different modes of action (Aureobasidin A, pyrethroids, organophosphates, carbamates, benzimidazoles, dithiocarbamates, and inorganic fungicides) into a single composition. This merging of compounds with different spectra of activity creates a synergistic effect that broadens the overall spectrum of activity against diverse phytopathogenic fungi while allowing for reduced individual application rates.
2Reliability
If higher application rates are used to achieve effective control, then the onset of action and residual activity improve, but crop tolerance may be compromised and environmental impact increases
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating compounds with different modes of action and toxicity profiles. Aureobasidin A provides effective fungal control at low concentrations, allowing the formulation to maintain reliable disease control while using lower overall application rates that preserve crop tolerance and reduce environmental harm.
3Adaptability or versatility
If fungicidal compositions with broader spectrum activity are developed, then resistance management improves, but the complexity of the composition increases
Solution Approach 1:
The patent creates a multi-functional composition where each compound class serves multiple purposes: Aureobasidin A provides primary fungicidal activity, pyrethroids and organophosphates contribute additional fungicidal effects and insect control, while carbamates, benzimidazoles, dithiocarbamates, and inorganic fungicides provide backup mechanisms and resistance management. This universality allows the single composition to address multiple fungal pathogens and resistance scenarios without requiring separate specialized formulations.
