Mesotrione Herbicide Blends for Post-Emergent Commelinid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides, such as herbicide A, lack sufficient activity, spectrum of activity, compatibility with useful plants, and reliable control of unwanted plants, particularly in post-emergent weed control, especially against Commelinids.
Innovation Solution
A composition comprising herbicide A and mesotrione, optionally with additional herbicides like saflufenacil, trifludimoxazin, glyphosate, glufosinate, 2,4-D, pyroxasulfone, imazethapyr, or dimethenamid-P, is applied post-emergently to enhance herbicidal activity through a synergistic effect, providing efficient weed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single herbicide A is used for post-emergent weed control, then the application is simple, but the herbicidal activity and spectrum of control are insufficient
Solution Approach 1:
The patent combines herbicide A with mesotrione and optionally other herbicides (saflufenacil, trifludimoxazin, glyphosate, glufosinate, 2,4-D, pyroxasulfone, imazethapyr, dimethenamid) to create a synergistic composition. This merging of multiple herbicidal agents with different modes of action achieves enhanced and broad-spectrum weed control, particularly against Commelinids, while maintaining manageable formulation complexity through standardized composition ratios.
2Reliability
If higher application rates of herbicide A are used to improve weed control, then herbicidal activity increases, but compatibility with useful plants decreases
Solution Approach 1:
The patent changes the compositional parameters by formulating herbicide A with specific ratios of mesotrione (0.1-10% w/w) and optional additional herbicides. This parameter optimization allows achieving effective weed control at lower individual herbicide concentrations, reducing phytotoxicity to crop plants while maintaining or enhancing overall herbicidal activity through synergistic interactions.
3Adaptability or versatility
If a broader spectrum of herbicides is combined to control more weed species, then the spectrum of activity increases, but the composition complexity increases
Solution Approach 1:
The patent creates a universal herbicidal composition where herbicide A serves as the base agent and is combined with mesotrione and optionally one or more additional herbicides from a defined group. This multi-functional formulation provides broad-spectrum control across multiple weed species including grasses and broadleaves, while maintaining a standardized structure that simplifies formulation and application despite the diversity of target weeds.
4Ease of operation
If post-emergent application is used to identify weed species accurately, then specific weed control is improved, but the action speed on emerged weeds is slower
Solution Approach 1:
The patent applies herbicide A in combination with mesotrione and optional additional herbicides as a post-emergent treatment that acts on already identified weed species. The synergistic composition accelerates the action speed on emerged weeds compared to herbicide A alone, while maintaining the advantage of post-emergent application that allows accurate weed species identification and targeted control decisions.
