Diclosulam Herbicide Blend for Post-Emergent Commelinid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides, such as diclosulam, face challenges in achieving effective post-emergent weed control, particularly for Commelinids, with limitations in activity, spectrum, application rates, compatibility with crops, and reliability.
Innovation Solution
A composition comprising herbicide A (e.g., ethyl 2-[2-[[3-chloro-5-fluoro-6-[3-methyl-2,6-dioxo-4-(trifluoromethyl)pyrimidin-1-yl]-2-pyridyl]oxy]phenoxy]acetate) and diclosulam, optionally with additional herbicides like saflufenacil, trifludimoxazin, glyphosate, or glufosinate, is applied post-emergently, exhibiting a synergistic herbicidal effect beyond additive activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single herbicide is used for post-emergent weed control, then the application is simple, but the herbicidal activity and spectrum of activity are insufficient
Solution Approach 1:
The patent combines multiple herbicides (herbicide A, diclosulam, and optionally herbicide C) into a single composition that is applied together. This merging of multiple active substances provides synergistic effects that enhance overall herbicidal activity and broaden the spectrum of weed control while maintaining the simplicity of a single application operation.
2Reliability
If higher application rates of herbicide are used to improve herbicidal activity, then weed control effectiveness increases, but compatibility with crop plants deteriorates
Solution Approach 1:
The patent optimizes the concentration parameters of multiple herbicides in the composition to achieve synergistic effects at lower individual dosages. By carefully adjusting the ratio and concentration of herbicide A, diclosulam, and optional herbicide C, the formulation achieves enhanced weed control effectiveness while maintaining safety and compatibility with crop plants at reduced application rates.
3Adaptability or versatility
If a broad spectrum of herbicides is used to control multiple weed types, then the spectrum of activity improves, but the complexity of the composition increases
Solution Approach 1:
The patent creates a multi-functional herbicidal composition that effectively controls multiple types of weeds (including Commelinids) through the synergistic combination of herbicide A, diclosulam, and optionally herbicide C. This universal formulation provides broad-spectrum activity against diverse weed species while maintaining a relatively simple composition structure that can be applied as a single treatment.
