Herbicidal Mixture Reducing 2,4-D and Dicamba via Isoxaben Synergy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to reduce the amounts of 2,4-D, dicamba, and MCPP in herbicidal mixtures while maintaining or increasing their efficacy in controlling weeds, as current formulations often require higher concentrations to achieve desired results.
Innovation Solution
The use of a novel herbicidal mixture comprising isoxaben, dithiopyr, 2,4-D, dicamba, and MCPP, which allows for reduced concentrations of 2,4-D, dicamba, and MCPP while maintaining or enhancing weed control efficacy, including pre-emergent and post-emergent control of weeds such as crabgrass and broadleaf species.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard herbicidal mixtures use higher concentrations of 2,4-D, dicamba, and MCPP, then weed control efficacy is improved, but the amount of harmful substances increases and environmental safety decreases
Solution Approach 1:
The patent combines isoxaben and dithiopyr with reduced amounts of 2,4-D, dicamba, and MCPP in a single herbicidal mixture. This merging of active ingredients allows the formulation to achieve effective weed control while reducing the total quantity of potentially harmful substances, thereby resolving the contradiction between efficacy and substance quantity.
Solution Approach 2:
The invention creates a composite herbicidal formulation integrating multiple active ingredients (isoxaben, dithiopyr, 2,4-D, dicamba, and MCPP) in specific proportions. This composite approach enables synergistic effects that enhance weed control efficacy while allowing reduction in the concentration of individual harmful components.
2Reliability
If standard herbicidal mixtures use higher concentrations of 2,4-D, dicamba, and MCPP, then weed control efficacy is improved, but environmental safety and non-target organism protection deteriorates
Solution Approach 1:
By merging isoxaben and dithiopyr with reduced concentrations of 2,4-D, dicamba, and MCPP, the formulation maintains effective weed control while minimizing harmful effects on non-target organisms and the environment, thus resolving the contradiction between efficacy and environmental safety.
Solution Approach 2:
The patent changes the concentration parameters of the herbicidal components, specifically reducing the amounts of 2,4-D, dicamba, and MCPP while incorporating isoxaben and dithiopyr. This parameter change maintains the overall efficacy through synergistic interactions while reducing environmental harm.
3Object-affected harmful factors
If herbicidal mixtures reduce the amounts of 2,4-D, dicamba, and MCPP, then environmental safety improves, but weed control efficacy may deteriorate
Solution Approach 1:
The composite formulation integrates isoxaben, dithiopyr, and reduced amounts of 2,4-D, dicamba, and MCPP to create a synergistic effect. This composite approach ensures that weed control efficacy is maintained even at lower concentrations of the previously dominant ingredients, resolving the contradiction between environmental safety and efficacy.
Solution Approach 2:
Isoxaben and dithiopyr act as intermediary components that enhance the herbicidal activity of the reduced 2,4-D, dicamba, and MCPP concentrations. This intermediary effect allows the formulation to maintain efficacy while reducing the amounts of potentially harmful substances.
