Solution Overview
Problem
Agrochemically active microbial formulations comprising pest-controlling filamentous fungi often face challenges with stability and emulsification when combined with oils, leading to inconsistent pest control effects and potential harm to plants.
Innovation Solution
A formulation combining an agrochemically active microbe with a specified ester compound and a surfactant, such as polyoxyethylene fatty acid ester, to create a stable and emulsified mixture that maintains microbe viability and avoids plant harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an agrochemically active microbe is combined with oil to increase pest control effect, then the pest control effect is enhanced, but the formulation becomes heterogeneous and unstable
Solution Approach 1:
The patent introduces a specific ester compound as an intermediary substance between the agrochemically active microbe and the oil carrier. This ester compound acts as a mediator that improves compatibility and emulsification, allowing the oil-based formulation to remain homogeneous while maintaining enhanced pest control effects. The ester compound specifically facilitates better interaction between the microbe and oil components.
Solution Approach 2:
The patent modifies the chemical composition parameters of the formulation by specifying particular ester compounds with defined molecular structures (formula I and II). By changing the chemical parameters - specifically using esters of polyhydric alcohols with fatty acids - the formulation achieves improved emulsification and stability while maintaining the oil-based pest control efficacy.
2Reliability
If formulation priority is given to microbe viability stability, then microbe viability is maintained, but the formulation is not well emulsified and becomes heterogeneous
Solution Approach 1:
The ester compound serves as a protective intermediary that creates a compatible environment for the microbe while also ensuring proper emulsification. This mediator substance allows the formulation to achieve both microbe viability stability and homogeneous emulsification simultaneously, resolving the contradiction between these two requirements.
Solution Approach 2:
The patent creates a composite formulation system consisting of three main components: the agrochemically active microbe, the oil carrier, and the specifically selected ester compound. This composite material approach allows the formulation to integrate multiple functions - microbe protection, emulsification, and pest control - into a single homogeneous system.
3Reliability
If a mixture of microbe and oil is applied to enhance pest control, then pest control effect increases, but harmful effects on plants may occur
Solution Approach 1:
The patent specifies precise chemical structure parameters for the ester compound (formula I and II with defined R1 and R2 groups) to ensure the formulation achieves enhanced pest control while maintaining plant safety. By controlling the chemical parameters of the ester - specifically using natural fatty acid esters of polyhydric alcohols - the formulation avoids plant harmful effects while maintaining effectiveness.
