Synergistic Herbicidal Composition for Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides are inadequate in effectively controlling undesirable vegetation in agriculture, as they often require multiple applications and can lead to herbicide resistance in weeds, necessitating the development of more potent and sustainable herbicidal compositions.
Innovation Solution
A synergistic herbicidal composition combining 4-amino-3-chloro-5-fluoro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylic acid or its agriculturally acceptable ester/salt with very long chain fatty acid (VLCFA) and fatty acid/lipid synthesis inhibiting herbicides, such as acetochlor, alachlor, and others, to enhance weed control efficacy.

Engineering Contradiction Analysis
1Reliability
If current herbicides are used to control undesirable vegetation, then some weed control is achieved, but multiple applications are required and herbicide resistance develops
Solution Approach 1:
The patent combines compound (I) with a VLCFA synthesis-inhibiting herbicide or fatty acid/lipid synthesis-inhibiting herbicide to create a synergistic mixture. This combination achieves superior weed control efficacy compared to individual herbicides, reducing the need for multiple applications while delaying herbicide resistance development through multi-mode-of-action.

3Reliability
If compound (I) is combined with VLCFA and fatty acid/lipid synthesis inhibiting herbicides, then herbicidal activity increases, but composition complexity increases
