Fluazinam and Carboxamide Synergy for Soybean Rust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current soybean disease control compositions, particularly those involving fluazinam and azole-based compounds, often exhibit insufficient control effects on soybean diseases and have short residual effectiveness when used alone.
Innovation Solution
Combining fluazinam or its salt with at least one fungicide selected from carboxamide-based and azole-based compounds, such as benzovindiflupyr, cyproconazole, epoxiconazole, and tebuconazole, to create a synergistic effect for enhanced fungicidal activity against soybean diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluazinam or azole-based compounds are used solely for soybean disease control, then the composition is simple and easy to apply, but the control effect is insufficient and residual effectiveness is short
Solution Approach 1:
The patent combines fluazinam with carboxamide-based compounds or azole-based compounds to create a mixed fungicidal composition. This merging of multiple active ingredients produces a synergistic effect that significantly improves control effectiveness and residual activity against soybean diseases, particularly soybean rust, while maintaining practical applicability through integrated formulation.
2Reliability
If multiple fungicides are combined to improve control effect, then the fungicidal activity is enhanced, but the composition becomes more complex
Solution Approach 1:
The patent creates a composite fungicidal composition by combining fluazinam with specific carboxamide-based compounds or azole-based compounds. This composite formulation leverages the complementary mechanisms of action of different fungicide classes to achieve synergistic effects, enhancing overall fungicidal activity while managing composition complexity through selective ingredient pairing and optimized ratios.
