Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant treatment methods using insect vectoring, such as bee vectoring, face challenges in effectively delivering biocontrol agents like Clonostachys rosea to plants while maintaining stability and avoiding moisture absorption, which affects the efficacy of the treatment.
Innovation Solution
A plant treatment formulation comprising particulate calcium silicate bonded with Clonostachys rosea spores, a stabilizing agent, a moisture absorption agent, an attracting agent, and a diluent, designed to be delivered through insect vectoring, ensuring the spores are retained on the bees and deposited on plants effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Clonostachys rosea spores are used as plant treatment agent, then disease resistance and germination enhancement are improved, but moisture absorption affects stability and delivery efficiency
Solution Approach 1:
The patent introduces an intermediary substance (carrier material such as diatomaceous earth, silica gel, or other absorbent materials) that mediates between the moisture-sensitive spores and the environment. This carrier absorbs excess moisture while protecting the spores from direct contact with water, thereby maintaining spore stability and preventing premature germination or degradation during storage and delivery.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the formulation by adjusting the ratio of spores to carrier material, controlling particle size distribution, and optimizing moisture content. These parameter changes create a formulation that maintains optimal moisture levels to protect spore stability while ensuring effective delivery to plants through insect vectors.
2Productivity
If insect vectoring is used for delivery, then delivery efficiency to plants is improved, but ensuring spore retention on bees requires specific formulation stability
Solution Approach 1:
The patent applies local quality by creating a formulation with specific physical properties suited for insect vectoring. The carrier material is selected and sized to adhere effectively to insect bodies (such as bees), ensuring that spores are retained on the vectors during transport. The formulation may include adjuvants or surface modifiers that enhance adhesion to insect cuticles, ensuring reliable spore retention without compromising delivery efficiency.
3Area of stationary object
If biocontrol agents are disseminated through bees, then treatment coverage is improved, but formulation must avoid moisture that affects efficacy
Solution Approach 1:
The carrier material serves as a protective intermediary that shields the biocontrol spores from moisture during the dissemination process. As bees transport the formulation, the carrier material absorbs and buffers moisture, preventing it from reaching the spores and compromising their efficacy. This allows wide treatment coverage through extensive bee foraging while maintaining spore viability.
