Solution Overview

Problem

Existing active compound combinations for controlling animal and microbial pests, particularly acarids and insects, often have unsatisfactory acaricidal and insecticidal efficacy and compatibility with crop plants, leading to a demand for novel combinations with improved properties.

Innovation Solution

A combination of compounds of formula (I) with specific substituents and Biological Control Agents (BCA) from Groups (1) to (7), particularly fatty acids or their derivatives, exhibiting synergistic effects for enhanced insecticidal, acaricidal, and nematicidal properties as well as plant strengthening agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compounds of formula (I) are used for pest control, then insecticidal activity is achieved, but acaricidal efficacy and compatibility with crop plants are unsatisfactory

Engineering Contradiction:

Improveacaricidal efficacyVSAvoidcompatibility with crop plants

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines compound (I) with Biological Control Agents (BCAs) from Groups (1) to (7) to create a synergistic mixture that simultaneously improves acaricidal efficacy and maintains compatibility with crop plants, resolving the contradiction between enhanced pest control performance and plant safety

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite active compound combination comprising compound (I) and BCAs, where the synergistic interaction between the chemical compound and biological agents enhances acaricidal activity while the natural origin of BCAs ensures compatibility with crop plants

Inventive Principle:

Principle #40Composite materials

2Reliability

If single active compounds are used, then application is simple, but insecticidal and acaricidal efficacy is insufficient

Engineering Contradiction:

Improveinsecticidal efficacyVSAvoidcombination complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges compound (I) with BCAs to achieve synergistic effects that dramatically enhance insecticidal and acaricidal efficacy, where the combined effect exceeds the sum of individual components, justifying the increased complexity

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If compound combinations are used to enhance efficacy, then pest control effectiveness increases, but compatibility with plants may deteriorate

Engineering Contradiction:

Improvepest control effectivenessVSAvoidplant damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses BCAs which are naturally derived substances that, when combined with compound (I), enhance pest control effectiveness while their natural origin ensures they do not harm crop plants, converting the potential harm of increased chemical activity into beneficial synergistic effects with improved plant safety

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
