Benzoxaborole Volatile Antimicrobial Agents for Pathogen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new uses of volatile antimicrobial agents, particularly in agricultural applications, and for combinations with volatile plant growth regulators to address pathogens affecting meats, plants, or plant parts.
Innovation Solution
The use of volatile antimicrobial compounds, such as certain oxaborole compounds like benzoxaboroles, is proposed, along with delivery systems that leverage their volatility, and combinations with plant growth regulators like 1-methylcyclopropene (1-MCP), for effective application against various pathogens through gas treatment methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antimicrobial agents are used, then pathogen control is achieved, but volatility and agricultural applicability are insufficient
Solution Approach 1:
The patent modifies the chemical structure of antimicrobial agents by introducing oxaborole rings with specific substituents (halogen, nitro, nitrile, amino, carboxy, acyl, aryloxy, carbonamido, sulfonamido, or trifluoromethyl groups) to enhance volatility while maintaining antimicrobial efficacy. This structural parameter change enables the compounds to be applied as gases to plants, fruits, and vegetables, resolving the contradiction between pathogen control and agricultural applicability
Solution Approach 2:
The patent utilizes the volatile nature of oxaborole compounds to deliver antimicrobial agents in gaseous form directly to agricultural products. The gas-phase delivery system allows uniform distribution of the antimicrobial agent across plant surfaces, fruits, and vegetables, achieving effective pathogen control while enabling practical agricultural application
2Reliability
If volatile antimicrobial compounds are applied, then pathogen inhibition is improved, but delivery system complexity increases
Solution Approach 1:
The oxaborole compounds inherently possess volatile properties that enable self-delivery as gases without requiring complex external delivery infrastructure. The compounds naturally evaporate and disperse in the air, allowing simple application methods such as placing treated materials in storage containers or applying during packing, thus achieving effective pathogen inhibition while minimizing delivery system complexity
3Ease of operation
If single antimicrobial compounds are used, then application simplicity is maintained, but disease control effectiveness is limited
Solution Approach 1:
The patent combines volatile oxaborole antimicrobial compounds with 1-methylcyclopropene (1-MCP), a volatile plant growth regulator, to create synergistic disease control. The combination leverages both the antimicrobial activity of oxaboroles and the ethylene inhibition properties of 1-MCP, enhancing overall disease control effectiveness while maintaining the simplicity of gas-phase application for both compounds
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 method provides effective inhibition of a wide range of pathogens, including fungal and bacterial species, with compounds like benzoxaboroles demonstrating 100% control at specific concentrations, and when combined with 1-MCP, enhances disease control and reduces phytotoxicity, offering a practical solution for agricultural applications.
Implementation Method 1
The volatile antimicrobial compounds provided include certain oxaborole compounds... contacting a meat, plant or plant part with an effective amount of the volatile antimicrobial compound, wherein said contacting comprises applying the volatile antimicrobial compound by way of gas treatment
