Pyridone Herbicidal Derivatives for Selective Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides do not effectively address the need for selective and efficient weed control in agricultural and horticultural settings, particularly in crops of useful plants.
Innovation Solution
Development of novel pyridone derivatives with specific structural features, such as C1-C6alkyl, C1-C6alkoxy, C2-C6alkenyl, C2-C6alkynyl, C1-C6alkoxyC1-C6alkyl, or C3-C6cycloalkyl substituents, which exhibit herbicidal activity when applied as active ingredients in agrochemical compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used, then weed control is achieved, but the herbicidal activity is insufficient for selective and efficient weed control in agricultural and horticultural settings
Solution Approach 1:
The patent applies parameter changes by systematically modifying the chemical structure of pyridone derivatives through varying substituents at different positions (R1-R6 groups including alkyl, alkoxy, alkenyl, alkynyl, cycloalkyl groups). These structural parameter changes result in compounds with enhanced herbicidal activity and improved selectivity for weed control in agricultural and horticultural settings, directly resolving the contradiction between sufficient herbicidal activity and selective control capability
