Imidazole Herbicidal Compounds for Selective Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides lack effective and selective control of weeds in crops, particularly in plants that are inherently tolerant or genetically modified to resist other herbicides.
Innovation Solution
Development of novel herbicidal imidazole compounds, formulated into compositions with agronomically acceptable salts and adjuvants, providing enhanced selectivity and efficacy against weeds while minimizing impact on crop plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used to control weeds, then weed control is achieved, but selectivity and efficacy are insufficient particularly against tolerant crops and genetically modified plants
Solution Approach 1:
The patent modifies the chemical structure of imidazole compounds by changing parameters such as substituting the phenyl group at position Q with 5-membered heteroaryl groups (pyridine, pyrimidine, triazine, oxazole, thiazole), altering substituents at positions R1-R4, and adjusting molecular weight and lipophilicity. These parameter changes create new chemical entities with improved selectivity and efficacy against weeds while reducing harm to tolerant crops and genetically modified plants.
Solution Approach 2:
The patent creates composite herbicidal compositions by combining the novel imidazole compounds with formulation adjuvants and other agronomically acceptable substances. These composite formulations enhance the overall performance, selectivity, and efficacy of the herbicide while minimizing negative impacts on crop plants, achieving superior weed control compared to single-component herbicides.
2Reliability
If herbicidal compositions are developed with enhanced selectivity, then weed control in tolerant crops is improved, but formulation complexity increases
Solution Approach 1:
The patent optimizes formulation parameters such as concentration levels, pH, viscosity, and compatibility with crop plants. By carefully adjusting these parameters in the herbicidal compositions, the patent achieves enhanced selectivity and efficacy while maintaining formulation stability and ease of application, avoiding excessive complexity.
