Synergistic Active Compound Combinations for Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active compound combinations for controlling animal and microbial pests, particularly acarids and nematodes, often have unsatisfactory acaricidal and insecticidal efficacy and compatibility with crops, leading to demand for novel combinations with improved properties.
Innovation Solution
A combination of at least one compound of formula (I) with specific IRAC classification group or formula (IIa/IIb) active compounds, or Biological Control Agents, which exhibit synergistic effects, enhancing insecticidal, acaricidal, nematicidal, and plant-strengthening properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing active compound combinations are used for pest control, then some pest control effect is achieved, but the acaricidal and insecticidal efficacy is not satisfactory
Solution Approach 1:
The patent combines compound (I) with compounds of formula (IIa) or (IIb) to create a synergistic mixture that achieves superior acaricidal and insecticidal efficacy. The combination of these specific chemical structures produces an effect greater than the sum of individual components, directly resolving the contradiction between reliable pest control and actual effectiveness.
Solution Approach 2:
The invention creates a composite active compound system consisting of compound (I) combined with compounds of formula (IIa) or (IIb). This composite material approach allows the mixture to exhibit enhanced biological activity and synergistic effects, transforming the insufficient efficacy of individual compounds into a highly effective pest control agent.
2Reliability
If existing active compound combinations are used, then some pest control is achieved, but compatibility with crop plants is not satisfactory
Solution Approach 1:
The patent modifies the chemical parameters by combining compound (I) with compounds of formula (IIa) or (IIb) in specific ratios and configurations. This parameter optimization achieves a balance where the mixture maintains high pest control reliability while reducing phytotoxicity and improving compatibility with crop plants through controlled compositional changes.
3Ease of operation
If single active compounds are used, then application is simple, but the synergistic effect and overall efficacy are limited
Solution Approach 1:
The patent merges compound (I) with compounds of formula (IIa) or (IIb) into a single combined application formulation. This merging maintains ease of operation by providing a ready-to-use mixture while simultaneously achieving superior synergistic insecticidal and acaricidal effects that neither compound could achieve alone.
