Solution Overview

Problem

Current fungicidal compounds and compositions often fail to provide adequate control over phytopathogenic fungi, lacking superior biological activity, broad spectrum of activity, improved safety profiles, and reduced environmental impact, necessitating the development of new compounds with enhanced properties for agricultural use.

Innovation Solution

A fungicidal composition comprising a mixture of compound (A) of formula (I) and component (B), where compound (A) is a specific picolinamide derivative and component (B) is selected from various known fungicides, applied in specific weight ratios to enhance biological activity and safety while reducing application frequency and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If single fungicidal compounds are used, then formulation simplicity is maintained, but biological activity and spectrum of activity are insufficient

Engineering Contradiction:

Improvespectrum of activityVSAvoidcomposition complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines two different fungicidal compounds (component A from formula I and component B from the specified group) into a single composition. This merging approach allows the composition to achieve a broader spectrum of activity against phytopathogenic fungi while maintaining manageable formulation complexity through defined component selection and ratio specifications.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If higher application rates are used, then biological activity is improved, but environmental impact and operator exposure increase

Engineering Contradiction:

Improvebiological activityVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the weight ratio parameter of component A to component B in the composition. By adjusting this parameter within specific ranges (e.g., 1:1 to 10:1), the composition achieves effective biological activity at reduced application rates, thereby lowering environmental impact and operator exposure while maintaining reliable disease control.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If multiple applications are made, then disease control effectiveness is improved, but time loss and operational complexity increase

Engineering Contradiction:

Improvedisease control effectivenessVSAvoidapplication frequency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent creates a composite fungicidal composition combining component A and component B with complementary modes of action. This composite approach provides broader spectrum coverage and more durable disease control, enabling reduced application frequency while maintaining effectiveness, thus reducing time loss and operational complexity.
