Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fungicidal compounds and compositions do not adequately address the needs of agricultural practice in terms of biological activity, spectrum of activity, safety profile, physico-chemical properties, biodegradability, and environmental impact, necessitating the development of new compositions with improved properties for controlling phytopathogenic fungi.
Innovation Solution
A fungicidal composition comprising a mixture of components (A) and (B), where component (A) is a compound of formula (I) and component (B) is selected from a group of specific fungicides, applied in various weight ratios to enhance biological activity, safety, and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fungicidal compounds are used, then some level of fungal control is achieved, but biological activity and spectrum of activity are insufficient
Solution Approach 1:
The patent combines two fungicidal compounds with different modes of action into a single composition. Component (A) inhibits ergosterol biosynthesis while component (B) disrupts fungal cell membranes, creating a synergistic effect that broadens the spectrum of activity and improves reliability against diverse phytopathogenic fungi.
Solution Approach 2:
The invention creates a composite fungicidal system by formulating a composition containing both component (A) and component (B) in specific ratios. This composite approach allows the composition to target multiple fungal pathways simultaneously, achieving both enhanced biological activity and expanded spectrum of activity.
2Reliability
If existing fungicidal compounds are used, then fungal control is achieved, but safety profile and environmental impact are inadequate
Solution Approach 1:
The patent optimizes the weight ratio of component (A) to component (B) within specific ranges (e.g., 10:1 to 1:10, 5:1 to 1:20, 3:1 to 1:10) to achieve the desired balance between efficacy and safety. This parameter optimization allows reduction of application rates while maintaining effectiveness, thereby improving safety profile and reducing environmental impact.
3Reliability
If higher application rates are used, then effective control is achieved, but environmental impact and operator exposure increase
Solution Approach 1:
By combining two active ingredients with complementary modes of action, the composition achieves effective fungal control at lower individual concentration levels. This synergistic combination allows reduction of total application rates, thereby decreasing operator exposure and environmental impact while maintaining effective control.
