Solution Overview

Problem

Existing active compound combinations for controlling animal and microbial pests, such as insects and mites, have unsatisfactory acaricidal and insecticidal efficacy, activity spectrum, and compatibility with crop plants.

Innovation Solution

A combination of at least one compound of formula (I) with specific substituents and at least one active compound from Biological Control Agent (BCA) Groups (1) to (7), which are selected for their biological control properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If known compounds of formula (I) are used for pest control, then insecticidal action is achieved, but acaricidal efficacy and activity spectrum are not satisfactory

Engineering Contradiction:

Improveacaricidal efficacyVSAvoidactivity spectrum

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent combines compound (I) with biological control agents from groups (2) to (7) to create a synergistic mixture that simultaneously improves acaricidal efficacy and broadens activity spectrum against multiple pest types including insects, mites, and nematodes

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite pest control composition comprising compound (I) and at least one biological control agent, where the combination produces enhanced effects beyond individual components, achieving both improved reliability and expanded productivity

Inventive Principle:

Principle #40Composite materials

2Reliability

If known compounds of formula (I) are applied to crops, then pest control is achieved, but compatibility with crop plants is not satisfactory

Engineering Contradiction:

Improvepest control efficacyVSAvoidcompatibility with crop plants

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses biological control agents as intermediary substances that mediate between compound (I) and crop plants, reducing direct harmful interactions while maintaining pest control efficacy through synergistic action of the combination

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If single active compounds are used for pest control, then application is simple, but efficacy and activity spectrum are limited

Engineering Contradiction:

Improveapplication simplicityVSAvoidinsecticidal and acaricidal efficacy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges compound (I) with biological control agents in a single applicible composition, maintaining ease of application while achieving enhanced and broadened pest control efficacy through the synergistic combination

Inventive Principle:

Principle #5Merging (Combining)
