Fungicidal Composition for Soybean Pathogen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commercial fungicides are limited in their ability to effectively control infestations by Corynespora cassiicola, Cercospora sojina, and Cercospora kikuchii, as these phytopathogens have developed resistance, and new classes of agrochemical fungicides often have restricted fungicidal spectra, failing to provide comprehensive control on soybean crops.
Innovation Solution
The use of 2-[2-(7,8-difluoro-2-methylquinolin-3-yloxy)-6-fluorophenyl]propan-2-ol and related compounds, applied as part of a pesticidal composition, to control or prevent infestation by these pathogens on various plants, including soybeans, through direct application or as part of a formulation with other biologically active agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current commercial fungicides are used, then some level of pathogen control is achieved, but resistance development in Corynespora cassiicola, Cercospora sojina, and Cercospora kikuchii limits their effectiveness
Solution Approach 1:
The patent combines two fungicides from different chemical classes (a triazole and a strobilurin, or other compatible combinations) into a single composition. This composite approach allows the formulation to target multiple pathogens including Corynespora cassiicola, Cercospora sojina, and Cercospora kikuchii simultaneously, overcoming resistance issues by utilizing different modes of action in each component.
Solution Approach 2:
The fungicidal composition is designed to provide broad-spectrum control against multiple phytopathogenic fungi that affect soybeans and other crops. The formulation achieves multi-functionality by effectively controlling target spot, frogeye leaf spot, and cercospora leaf blight with a single application, eliminating the need for separate treatments for each pathogen.
2Reliability
If new classes of agrochemical fungicides are developed, then control of specific phytopathogens is improved, but the fungicidal spectrum is restricted to certain crops and pathogens
Solution Approach 1:
The patent merges fungicides from different chemical classes with complementary spectra of activity into a single formulation. By combining agents that target different physiological pathways in fungi, the composition achieves both specific control of targeted pathogens and broader spectrum coverage against related phytopathogens.
Solution Approach 2:
The formulation integrates multiple active ingredients with different chemical structures and modes of action, creating a composite fungicide that simultaneously provides narrow-spectrum precision targeting and broad-spectrum coverage. This allows effective control across multiple crop types and pathogen species.
3Ease of operation
If single fungicide applications are used, then application simplicity is maintained, but comprehensive control against multiple resistant pathogens is insufficient
Solution Approach 1:
The patent combines multiple fungicidal agents into a single pre-mixed formulation that maintains ease of application while delivering comprehensive pathogen control. The unified product eliminates the need for separate mixing and application of individual fungicides, preserving operational simplicity.
Solution Approach 2:
The single fungicidal composition performs multiple functions simultaneously by targeting different pathogens through different modes of action, providing comprehensive control against Corynespora cassiicola, Cercospora sojina, Cercospora kikuchii, and other phytopathogens in one application.
