Nanobubble Water Powdery Mildew Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling powdery mildew, such as using azole fungicides, face issues with drug resistance and safety concerns, and require effective management of eucalyptus leaf extract and water-soluble chitosan concentrations.
Innovation Solution
Applying nanobubble water with high oxygen concentrations and specific bubble sizes to plants, either alone or diluted with agrochemicals, to effectively control powdery mildew by washing out pathogens and killing them through cleansing action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If azole fungicides are used to control powdery mildew, then the controlling effect is improved, but drug resistance of pathogens emerges and safety problems occur
Solution Approach 1:
The patent changes the chemical composition parameters by using eucalyptus leaf extract (specific concentration range) combined with water-soluble chitosan, replacing conventional azole fungicides. This parameter change achieves powdery mildew control while avoiding drug resistance and safety issues associated with traditional chemicals.
Solution Approach 2:
The patent creates a composite formulation by combining eucalyptus leaf extract and water-soluble chitosan in specific ratios. This composite approach enhances the controlling effect while reducing the harmful side effects, as the synergistic interaction between the two components provides effective disease control without inducing pathogen resistance.
2Object-affected harmful factors
If eucalyptus leaf extract and water-soluble chitosan are used, then safety problems are reduced, but concentration management becomes complex
Solution Approach 1:
The patent specifies optimal concentration ranges (eucalyptus leaf extract: 0.1-10% by weight, water-soluble chitosan: 0.01-5% by weight) to simplify the management complexity. By establishing these precise parameter ranges, the patent makes the formulation easy to prepare and apply while maintaining safety advantages over conventional fungicides.
3Ease of operation
If conventional fungicides are used, then the operation is simple, but drug resistance and safety issues arise
Solution Approach 1:
The patent maintains operational simplicity by providing clear preparation instructions: mixing eucalyptus leaf extract and water-soluble chitosan in specified concentrations with water. This parameter-based formulation approach keeps the operation straightforward while eliminating the harmful effects of conventional fungicides.
