Synergistic Active Substance Combinations for Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insecticidal compounds fail to meet agricultural requirements, such as reducing dosage rates, controlling resistant pests, and ensuring safety and efficacy on plant propagation materials, while maintaining low toxicity to plants and warm-blooded species.
Innovation Solution
Combining specific compounds of formula (I) with neonicotinoids, like thiacloprid and imidacloprid, to create synergistic active substance combinations that enhance insecticidal and acaricidal activity, widening the pest control spectrum and improving safety and plant tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If compounds of formula (I) or neonicotinoids are used individually, then insecticidal activity is achieved, but dosage rates are too high and spectrum of control is insufficient
Solution Approach 1:
The patent combines compounds of formula (I) with neonicotinoids in synergistic mixtures, where the combination achieves broader pest spectrum control and allows reduced dosage rates compared to individual compounds. The synergistic interaction between the two compound classes enhances overall efficacy while reducing the quantity of each substance needed.
2Reliability
If higher dosage rates are used to control resistant pests, then pest control efficacy is improved, but toxicity to plants and warm-blooded species increases
Solution Approach 1:
The patent changes the chemical composition parameters by combining two different compound classes (formula (I) compounds and neonicotinoids) with different modes of action. This parameter change allows control of resistant pests through synergistic effects while maintaining lower individual dosage rates, thereby reducing toxicity to non-target organisms including plants and warm-blooded species.
3Device complexity
If single active substances are used, then application simplicity is maintained, but additional effects such as fungicidal or nematicidal activity are not achieved
Solution Approach 1:
The patent creates a multi-functional active substance combination where the mixture of compounds of formula (I) and neonicotinoids provides not only insecticidal activity but also additional effects such as fungicidal, nematicidal, and acaricidal properties. This universal approach allows a single application to address multiple pest types and additional plant pathogens, enhancing versatility without significantly increasing application complexity.
