Concentrated Pyrethroid Insecticide Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pyrethroid insecticidal compositions have high costs per hectare and environmental impact due to high concentrations of surfactants and solvents, with limited effectiveness and toxicological classification compared to lower concentrated formulations.
Innovation Solution
A pyrethroid insecticidal composition with a concentration of 425 to 750 g/l of alpha-cypermethrin, beta-cypermethrin, or cypermethrin, using biodiesel, glycol, or aromatic naphtha solvents, and reduced surfactant amounts, which reduces environmental impact and cost while maintaining or exceeding the effectiveness of lower concentrated formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the concentration of pyrethroid compound is increased from 25-250 g/l to 425-750 g/l, then the cost per hectare and environmental impact are reduced, but the formulation complexity and manufacturing difficulty increase
Solution Approach 1:
The patent changes the concentration parameter of pyrethroid compound from conventional 25-250 g/l to 425-750 g/l, and adjusts the surfactant concentration parameter to 5-20 g/l (lower than conventional formulations). This parameter optimization enables high-concentration formulations while maintaining stability and effectiveness, resolving the contradiction between concentration increase and formulation complexity.
2Object-generated harmful factors
If the amount of surfactant is reduced by eight times, then the environmental impact and cost per hectare are reduced, but the emulsion stability and effectiveness may deteriorate
Solution Approach 1:
The patent optimizes the surfactant concentration parameter to a specific range of 5-20 g/l, which is eight times lower than conventional formulations. This parameter change, combined with the high pyrethroid concentration, maintains adequate emulsion stability and effectiveness while dramatically reducing environmental impact and cost.
Solution Approach 2:
The patent uses a composite formulation system combining high-concentration pyrethroid compound (425-750 g/l) with reduced surfactant (5-20 g/l) in a synergistic manner. This composite approach allows the system to achieve both low environmental impact and maintained emulsion stability, resolving the contradiction between surfactant reduction and reliability.
3Quantity of substance
If the applied volume of emulsifiable concentrate is reduced by five times, then the cost per hectare and environmental impact are reduced, but the probability of insect contact with the product decreases
Solution Approach 1:
The patent changes the active ingredient concentration parameter to 425-750 g/l, which is 5 times higher than conventional formulations. This enables the applied volume to be reduced by 5 times while maintaining the same amount of active ingredient per hectare, thereby reducing cost and environmental impact while preserving effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves equivalent or greater biological effectiveness with a significantly reduced amount of emulsified droplets, lower environmental impact, and lower costs per hectare by using fewer surfactants and solvents, resulting in improved ecological and economic benefits.
Implementation Method 1
the active ingredient is solubilized if it is initially solid or diluted if it is initially liquid in a solvent generally insoluble in water
Implementation Method 2
This solution comprising active material in an appropriate solvent, generally organic, is adjuvanted with one or more surfactants to allow emulsion in water during its final use
