Fungicidal Combinations for Synergistic Disease Control and Crop Yield

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for more effective agrochemical agents to combat fungal diseases in plants, as the use of fluconazole in agriculture is not fully explored, and existing fungicides lack synergistic combinations with other agrochemicals for enhanced efficacy and yield improvement.

Innovation Solution

A fungicidal combination comprising an azole fungicide, a multisite contact fungicide, and a systemic fungicide, which enhances fungal disease control, delays senescence, and increases crop yield by improving photosynthesis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fluconazole is used alone in agriculture, then it provides basic fungal disease control, but its efficacy is limited and not fully explored for agrochemical use

Engineering Contradiction:

Improvefungal disease control efficacyVSAvoidagrochemical application range

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines fluconazole with other fungicides (mancozeb, isopyrazam, metalaxyl, carbendazim, thiophanate-methyl) to create synergistic formulations that enhance fungal disease control efficacy beyond what fluconazole can achieve alone in agricultural settings

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If existing fungicides are used individually, then they provide specific disease control, but they lack synergistic combinations for enhanced efficacy

Engineering Contradiction:

Improvedisease control efficacyVSAvoidcrop yield improvement

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent creates multi-fungicide combinations that leverage synergistic effects between different active ingredients, resulting in enhanced disease control and improved crop yield compared to individual fungicide applications

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent develops composite fungicidal formulations containing multiple active ingredients with different modes of action, which work together to provide superior disease control and yield enhancement compared to single-ingredient products

Inventive Principle:

Principle #40Composite materials

3Productivity

If single fungicide applications are used, then they simplify the treatment process, but they result in early senescence and reduced crop yield

Engineering Contradiction:

Improvecrop yieldVSAvoidsenescence timing

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The patent combines multiple fungicides with complementary modes of action to delay senescence and extend the productive period of crops, thereby increasing overall yield compared to single fungicide applications

Inventive Principle:

Principle #5Merging (Combining)
