Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fungicidal compounds and compositions often fail to provide adequate control over phytopathogenic fungi, lacking superior biological activity, broad spectrum of activity, improved crop tolerance, and reduced environmental impact.
Innovation Solution
A fungicidal composition comprising a mixture of components (A) and (B) as active ingredients, where component (A) is a compound of Formula (I) and component (B) is selected from a group of known fungicides, applied in various weight ratios to achieve enhanced biological activity and improved crop protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fungicidal compounds are used, then application rates can be maintained, but biological activity and crop tolerance are insufficient
Solution Approach 1:
The patent combines two fungicidal compounds with different modes of action into a single composition. Component (A) from Formula (I) provides one mechanism of action while component (B) provides a complementary mechanism, creating synergistic effects that enhance biological activity while reducing individual application rates and improving crop tolerance.
Solution Approach 2:
The invention creates a composite fungicidal composition where component (A) and component (B) work together in defined weight ratios. This composite approach allows the composition to exhibit properties superior to individual components, achieving enhanced efficacy and improved safety profile simultaneously.
2Reliability
If higher application rates are used to improve control, then biological activity increases, but environmental impact and operator exposure increase
Solution Approach 1:
By merging two compounds with different modes of action, the composition achieves synergistic control effectiveness at lower total application rates. This reduces the amount of active ingredients released into the environment and minimizes operator exposure while maintaining or improving control effectiveness.
Solution Approach 2:
The invention changes the parameter of application rate by using a more efficient composition that requires lower amounts of active ingredients to achieve the same or better control效果. This parameter change directly reduces environmental load and operator exposure.
3Reliability
If multiple applications are used to maintain control, then disease protection is improved, but productivity decreases and environmental impact increases
Solution Approach 1:
The combination of two compounds with different modes of action provides complementary protection mechanisms that extend the duration of efficacy. This allows longer intervals between applications, reducing the total number of applications needed while maintaining disease protection levels.
Solution Approach 2:
The composition provides enhanced residual activity through the synergistic interaction of components (A) and (B), where the combined effect exceeds the sum of individual activities. This excessive action in terms of protection duration reduces the frequency of re-application needed.
4Adaptability or versatility
If single-mode fungicides are used, then composition simplicity is maintained, but spectrum of activity is limited
Solution Approach 1:
The patent merges two compounds with different modes of action to create a composition with a broader spectrum of activity. This combination approach allows the composition to target multiple phytopathogenic fungi that may have different sensitivities, expanding the effective spectrum while keeping the composition structure relatively simple with just two defined components.
