Herbicidal Composition Synergy Tribenuron Metsulfuron Florasulam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides often exhibit adverse side effects on crops and soil, and there is a need for herbicidal compositions that can effectively control a broader spectrum of weeds with reduced doses, while minimizing environmental impact and weed resistance, as existing combinations do not consistently demonstrate synergistic effects across different weed species and conditions.
Innovation Solution
A herbicidal composition comprising tribenuron-methyl, metsulfuron-methyl, and florasulam in specific weight proportions, optionally with non-ionic surface active agents, which when applied synergistically, reduces individual herbicide doses and broadens the activity spectrum, enhancing herbicidal activity and controlling a greater number of weed species.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If herbicides are used to control weeds, then weed control effectiveness is improved, but adverse side effects on crops and soil increase
Solution Approach 1:
The patent combines three herbicides (tribenuron-methyl, metsulfuron-methyl, and florasulam) into a single composition with specific weight proportions. This merging approach creates synergistic effects that enhance weed control effectiveness while allowing reduced doses of individual herbicides, thereby minimizing adverse side effects on crops and soil.
Solution Approach 2:
The patent specifies precise weight proportions for the herbicide components (tribenuron-methyl: 35-75%, metsulfuron-methyl: 10-30%, florasulam: 10-30%) to optimize the balance between effectiveness and safety. By changing the concentration parameters of individual herbicides within this composition, the patent achieves effective weed control with reduced harmful effects.
2Object-affected harmful factors
If herbicide doses are reduced to minimize environmental impact, then environmental care is improved, but herbicidal activity may be insufficient
Solution Approach 1:
By merging three herbicides with different modes of action and spectral activities into a single composition, the patent achieves enhanced synergistic herbicidal activity at reduced doses. The combination allows each herbicide to contribute its specific activity, maintaining overall effectiveness while reducing the dose of individual substances and thus minimizing environmental impact.
Solution Approach 2:
The patent creates a composite herbicidal composition with specific weight proportions of multiple active substances. This composite approach leverages the complementary properties of each herbicide to achieve superior overall performance at lower individual doses, balancing environmental care with maintained herbicidal activity.
3Adaptability or versatility
If existing herbicide combinations are used to broaden spectrum of activity, then weed control coverage is improved, but synergistic effects are not consistently observed
Solution Approach 1:
The patent optimizes the weight proportions of the three herbicide components to achieve consistent synergistic effects across different weed species and environmental conditions. By precisely controlling the concentration parameters within the specified ranges, the composition maintains reliable synergistic activity while broadening the spectrum of weed control.
Solution Approach 2:
The patent assigns specific roles to each herbicide component based on their individual properties: tribenuron-methyl provides broad spectrum activity, metsulfuron-methyl extends activity period, and florasulam enhances spectrum and reduces doses. This local specialization of functions within the composition ensures consistent synergistic effects across different applications.
