Anthranilic Diamide Coating for Propagule Insecticidal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anthranilic diamides have low water solubility, making it difficult for them to mobilize effectively within geotropic propagules and developing roots, leading to inadequate insecticidal concentrations in plant tissues, especially in foliage, which requires higher doses and results in dilution and vulnerability to absorption by the growing medium.
Innovation Solution
A composition comprising 9-91% anthranilic diamide insecticides and 9-91% nonionic fatty alcohol ethoxylates with specific water solubility and hydrophilic-lipophilic balance values, applied as a coating to geotropic propagules, facilitating absorption and distribution of insecticidally effective concentrations throughout the plant, including foliage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anthranilic diamides are applied as coatings to propagules, then insecticidal protection is provided, but low water solubility impedes mobilization and absorption into propagules and developing roots
Solution Approach 1:
The patent applies parameter changes by modifying the physical-chemical properties of anthranilic diamides through formulation with adjuvants and carriers that enhance water solubility and mobility. The composition parameters are optimized to improve dissolution and transport while maintaining insecticidal activity.
Solution Approach 2:
The patent uses composite materials by formulating anthranilic diamides with adjuvants, carriers, and other compounds to create a composite composition that overcomes the low water solubility limitation while preserving the core insecticidal function.
2Reliability
If greater amounts of anthranilic diamides are absorbed to protect foliage, then protection of foliage beyond first couple leaves is achieved, but increased absorption requirement leads to higher doses and dilution in rapidly expanding plant tissue
Solution Approach 1:
The patent changes the concentration and distribution parameters of anthranilic diamides in the plant system. By optimizing the formulation, the patent achieves more efficient uptake and translocation, reducing the total quantity required while maintaining effective protection concentrations in foliage.
Solution Approach 2:
The patent introduces adjuvants and carriers as intermediaries that facilitate the transport of anthranilic diamides through the plant system. These intermediaries enhance mobility and reduce the amount of active ingredient needed to achieve effective concentrations in distant foliage.
3Reliability
If anthranilic diamides are applied to propagules, then translocation within plants protects new growth, but vulnerability to absorption and dissipation through growing medium occurs before absorption
Solution Approach 1:
The patent applies preliminary action by pre-formulating anthranilic diamides with adjuvants and carriers that enhance immediate uptake and binding to propagule tissues. This preliminary formulation action prevents loss to the growing medium before the active ingredient can be absorbed and distributed.
Solution Approach 2:
The patent modifies the physicochemical parameters of the anthranilic diamide formulation to improve binding affinity to propagule surfaces and reduce solubility in the growing medium, thereby minimizing premature dissipation while maintaining ability to translocate after absorption.
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 enhances the absorption of anthranilic diamides into propagules and roots, providing sustained insecticidal protection to both lower and upper foliage, reducing the need for higher doses and minimizing vulnerability to absorption by the growing medium.
Implementation Method 1
promoting the absorption of anthranilic diamide insecticides into propagules and developing roots
Implementation Method 2
the low water solubility of anthranilic diamide insecticides impedes their mobilization through moisture
Implementation Method 3
the rapidly expanding volume of plant tissue in growing foliage inherently dilutes anthranilic diamide concentrations, absorption of increased amounts of anthranilic diamides is required
Implementation Method 4
coating the propagule with an insecticidally effective amount of the aforedescribed liquid composition and then evaporating the volatile aqueous liquid carrier of the composition
