Fungicidal Composition Synergy for Broad-Spectrum Plant Disease Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant disease control compositions are inadequate in providing effective control against a wide range of plant diseases, as they often lack comprehensive and consistent efficacy across various pathogens and crop types.
Innovation Solution
A plant disease control composition comprising a compound represented by formula (I) in combination with at least one of metrafenone, cyflufenamid, quinoxyfen, or proquinazid, applied in a weight ratio of 1:100 to 100:1, which is formulated into various dosage forms and applied to plants, seeds, or soil to provide broad-spectrum disease control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single compound is used for plant disease control, then the composition is simple and easy to manufacture, but the control effect against a wide range of plant diseases is insufficient
Solution Approach 1:
The patent combines compound (I) with at least one compound from Group A (metrafenone, cyflufenamid, quinoxyfen, or proquinazid) to create a synergistic mixture that provides broad-spectrum plant disease control. This merging of different chemical compounds resolves the contradiction by achieving both manufacturing feasibility and enhanced disease control efficacy through synergistic interactions between the compounds.
Solution Approach 2:
The invention creates a composite fungicidal composition comprising compound (I) and Group A compounds in specific weight ratios (1:100 to 100:1). This composite approach allows the formulation to leverage the complementary properties of different compounds, providing reliable control across multiple plant disease types while maintaining practical manufacturability.
2Reliability
If multiple compounds are combined to achieve broad-spectrum control, then the disease control efficacy is improved, but the composition complexity increases
Solution Approach 1:
The patent merges compound (I) with a limited selection of Group A compounds (metrafenone, cyflufenamid, quinoxyfen, or proquinazid) to achieve broad-spectrum disease control. By selecting from a specific group of compounds with complementary modes of action, the invention provides effective multi-pathogen control while managing formulation complexity through a focused compound selection rather than indiscriminate mixing of multiple agents.
3Reliability
If a specific weight ratio range is used for the compound combination, then the control effect is optimized, but the formulation flexibility is reduced
Solution Approach 1:
The patent specifies a weight ratio range of 1:100 to 100:1 for compound (I) to Group A compounds, which optimizes the synergistic effect while providing sufficient formulation flexibility. This parameter range allows formulators to adjust ratios based on specific disease targets, crop types, and resistance patterns while maintaining effective control, thus balancing optimized efficacy with practical formulation adaptability.
