Pyridate and 4-HPPD Inhibitor Composition for Synergistic Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides face challenges in achieving targeted synergistic activity against specific species of unwanted vegetation, require better overall selectivity, and often result in chemical, physical, or biological incompatibilities when combined, leading to inefficiencies and environmental concerns.
Innovation Solution
A synergistically effective herbicide composition combining pyridate with specific 4-HPPD inhibitors, such as mesotrione, topramezone, tembotrione, and sulcotrione, at optimized weight ratios, enhancing herbicidal activity through a synergistic effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple herbicides are combined to achieve synergistic activity, then herbicidal efficacy is improved, but chemical or biological incompatibility occurs leading to decomposition or antagonism
Solution Approach 1:
The patent optimizes the weight ratio parameters of pyridate and 4-HPPD inhibitor components to achieve synergistic herbicidal activity while preventing chemical incompatibility. By establishing specific ratio ranges, the invention transforms the combination from potentially incompatible to synergistically effective
Solution Approach 2:
The patent introduces formulation auxiliaries and additives as intermediaries to mediate between pyridate and 4-HPPD inhibitor components, preventing direct chemical incompatibility while maintaining synergistic herbicidal activity
2Productivity
If higher application rates are used to improve control results, then herbicidal activity is improved, but environmental impact increases due to leaching and carry-over effects
Solution Approach 1:
The invention changes the effectiveness parameter by achieving synergistic activity at lower application rates through optimized component ratios, thereby reducing environmental impact while maintaining control effectiveness
Solution Approach 2:
The patent creates a composite herbicide formulation combining pyridate and 4-HPPD inhibitor in specific ratios, where the composite achieves greater efficacy per unit of active compound, reducing overall environmental loading
3Productivity
If higher application rates are used to achieve good control results, then herbicidal activity is improved, but the amount of active compound input into the environment increases
Solution Approach 1:
The invention optimizes the concentration and ratio parameters of active compounds to achieve synergistic effects at lower total application rates, reducing the quantity of substance entering the environment while maintaining control effectiveness
