Herbicidal Composition Synergy Sulfentrazone Propyzamide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicidal compositions and methods are insufficient in effectively controlling undesirable vegetation, particularly in crops with herbicide-resistant or tolerant weeds, and there is a need for improved formulations that offer synergistic effects when combined.
Innovation Solution
The use of a herbicidal composition comprising sulfentrazone and propyzamide, which can be applied alone or with other herbicides, exhibiting synergistic effects to control a wide range of weeds, including resistant and tolerant species, through various application methods and ratios, and can be used in conjunction with adjuvants and carriers to enhance efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single herbicide applications are used, then application simplicity is maintained, but weed control efficacy is insufficient particularly against resistant biotypes
Solution Approach 1:
The patent combines sulfentrazone and propyzamide into a single herbicidal composition to achieve synergistic weed control effects. This merging of two different herbicide modes of action allows the composition to effectively control a broader spectrum of weeds including resistant biotypes, while maintaining practical application simplicity as a unified formulation.
2Adaptability or versatility
If herbicide compositions are optimized for specific weed species, then control precision is improved, but adaptability to diverse crop settings is reduced
Solution Approach 1:
The herbicidal composition containing sulfentrazone and propyzamide is designed with multi-functional capability to control various weed species across different crop settings. The combination of these two herbicides provides broad-spectrum activity that adapts to diverse agricultural environments while maintaining effective control of both grass and broadleaf weeds through their complementary modes of action.
