Solution Overview
Problem
Current herbicidal compositions are not sufficient for effectively controlling undesired plants, including weeds, and lack synergistic herbicidal effects when combining specific herbicides.
Innovation Solution
A herbicidal composition comprising metobromuron and at least one herbicidal compound selected from chlorpropham, S-metolachlor, flufenacet, pyroxasulfone, nicosulfuron, fluazifop-P-butyl, prometryn, ioxynil, pendimethalin, trifluralin, prosulfocarb, thiobencarb, and indanofan, or their salts, applied in a herbicidally effective amount to achieve synergistic herbicidal effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional herbicidal compositions are used, then existing weed control is achieved, but synergistic herbicidal effects are not obtained and control effectiveness is insufficient
Solution Approach 1:
The patent combines metobromuron with at least one herbicidal compound from a specific group (chlorpropham, S-metolachlor, flufenacet, pyroxasulfone, nicosulfuron, fluazifop-P-butyl, prometryn, ioxynil, pendimethalin, trifluralin, prosulfocarb, thiobencarb, or indanofan) to achieve synergistic herbicidal effects. This combination approach merges the actions of multiple herbicides with different modes of action to enhance overall weed control effectiveness beyond what single herbicides can achieve alone.
Solution Approach 2:
The invention creates a composite herbicidal composition by formulating metobromuron in combination with specific herbicidal compounds. This composite approach integrates multiple active ingredients with complementary mechanisms of action, resulting in a herbicidal mixture that exhibits enhanced efficacy and broader spectrum control compared to individual components.
2Reliability
If higher doses of herbicides are applied to improve control effectiveness, then weed killing ability increases, but safety to crop plants may be compromised
Solution Approach 1:
The patent utilizes parameter changes in herbicide combination ratios and dosing strategies to optimize the balance between weed control effectiveness and crop plant safety. By adjusting the proportions of metobromuron and accompanying herbicides, the formulation achieves enhanced efficacy at reduced doses, thereby maintaining crop safety while improving weed control.
Solution Approach 2:
The invention applies local quality by selecting specific herbicidal compounds that target particular weed types or growth stages, allowing differentiated control strategies. This enables enhanced effectiveness against specific weed problems while minimizing broad-spectrum impacts on crop plants, achieving precision in herbicidal action.
3Productivity
If multiple herbicidal compounds are combined to increase activity, then synergistic effects are achieved, but formulation complexity increases
Solution Approach 1:
The patent applies segmentation by organizing the herbicidal composition around metobromuron as a core component, with specific herbicidal compounds from a defined group serving as complementary agents. This segmented approach categorizes the multiple ingredients by their specific functions and modes of action, making the complex formulation more manageable and easier to optimize for different weed control scenarios.
