Hydroxycinnamic Acid Polymer Herbicide Enhancer for Lower-Dose Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides are often environmentally polluting, require frequent reapplication, and are not as effective, especially with increasing weed resistance, necessitating a composition that reduces herbicide dosage while maintaining efficacy and minimizing harm to crops and the environment.
Innovation Solution
A herbicide enhancer agent comprising a polymer of hydroxycinnamic acid with an average molecular mass higher than 400 g/mol, which synergistically enhances herbicide activity, allowing lower herbicide doses without impacting plant growth or yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional herbicides are used to control weeds, then weed control efficacy is achieved, but environmental pollution and harm to crops increase
Solution Approach 1:
The patent introduces a polymer of hydroxycinnamic acid as an intermediary substance that enhances herbicide activity. This polymer acts as a mediator between the herbicide and weed targets, enabling the herbicide to work more effectively at lower doses, thereby reducing environmental pollution and crop harm while maintaining weed control efficacy
Solution Approach 2:
The patent changes the parameter of herbicide dosage by using the polymer enhancer to achieve the same weed control effect with reduced herbicide quantities. The polymer modification allows for lower effective concentrations of the herbicide, thus reducing harmful effects on the environment and crops
2Object-affected harmful factors
If herbicide dosage is reduced to minimize environmental harm, then environmental and health risks decrease, but herbicidal efficacy may be compromised
Solution Approach 1:
The polymer of hydroxycinnamic acid serves as an intermediary that bridges the gap between reduced dosage and maintained efficacy. It enhances the herbicide's activity at lower concentrations, ensuring that reduced dosing does not compromise weed control effectiveness
Solution Approach 2:
The patent creates a composite formulation combining the herbicide with the polymer of hydroxycinnamic acid. This composite material synergistically enhances the herbicidal activity, allowing effective weed control at reduced herbicide doses while maintaining environmental and health safety
3Reliability
If existing herbicide compositions are used, then weed control is achieved, but frequent reapplication is required due to decreasing efficacy
Solution Approach 1:
The patent modifies the herbicide composition by adding the polymer of hydroxycinnamic acid, which changes the efficacy parameters and allows for extended duration of action. This reduction in reapplication frequency is achieved through the enhanced and prolonged effectiveness of the herbicide-polymer complex
