Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Farmers face challenges in protecting seeds and plant roots and shoots from soil and foliar insects due to rapid resistance development in pests against individual pesticidal compounds, necessitating a solution that enhances protection, reduces dosage, and expands activity spectrum.

Innovation Solution

Contacting seeds before sowing or after pregermination with 2-cyanobenzenesulfonamide compounds of a specific formula, which exhibit aphicidal or insecticidal activity, providing protection against soil and foliar insects and managing resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If repeated and exclusive application of an individual pesticidal compound is used, then protection against insects is achieved, but resistance development in pests occurs rapidly

Engineering Contradiction:

Improveprotection effectivenessVSAvoidresistance management

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines multiple pesticidal compounds with different modes of action into a single seed treatment composition. This mixture approach allows simultaneous protection against multiple pest types while reducing resistance development, as pests are exposed to multiple active ingredients rather than a single compound repeatedly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The seed treatment composition is designed to provide multi-functional protection against soil insects, foliar insects, and other pests through a single application. The composition includes compounds with different spectral activities, making the treatment universally effective against diverse pest populations while managing resistance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If standard dosages of pesticidal compounds are applied, then insect protection is provided, but higher dosages are needed when resistance develops

Engineering Contradiction:

Improveprotection effectivenessVSAvoiddosage rate

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

By merging compounds with different modes of action in a single composition, the patent achieves synergistic or additive effects that maintain protection effectiveness at lower total dosage rates, even when some resistance develops to individual components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent uses a composite pesticidal composition containing multiple active ingredients with different chemical structures and modes of action. This composite approach ensures that when resistance develops to one component, other components continue to provide protection, maintaining effectiveness without increasing overall dosage.

Inventive Principle:

Principle #40Composite materials

3Adaptability or versatility

If a broad spectrum of pesticidal compounds is used, then protection against multiple pest types is achieved, but resistance development accelerates

Engineering Contradiction:

Improvespectrum of activityVSAvoidresistance management

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies different pesticidal compounds with specific spectral activities to different functional zones within the seed treatment composition. Each compound targets specific pest types or physiological pathways, providing localized protection while maintaining overall spectral breadth without accelerating general resistance.

Inventive Principle:

Principle #3Local quality
