Herbicidal Composition Combining Group A Compounds with 2,4-D Choline Salt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current weed control methods using herbicides often lack efficacy in effectively managing a wide range of weeds in agricultural and non-cultivated areas, particularly in soybean, cotton, and corn fields, where herbicide-resistant crops are prevalent.
Innovation Solution
A herbicidal composition comprising a combination of specific herbicides such as flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen, and 2,4-D choline salt, with optional inclusion of glyphosate, applied in specific weight ratios to achieve enhanced weed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single herbicide is used for weed control, then the application is simple and cost-effective, but the control effect on diverse weeds including herbicide-resistant varieties is insufficient
Solution Approach 1:
The patent combines multiple herbicides with different modes of action (flumioxazin, sulfentrazone, saflufenacil, oxyfluorfen, fomesafen, and 2,4-D choline salt) into a single composition. This merging of different active ingredients provides synergistic effects that enhance weed control efficacy while maintaining practical application simplicity.
Solution Approach 2:
The invention creates a composite herbicidal formulation containing multiple chemically distinct herbicides. This composite approach allows the composition to target different weed species and resistance mechanisms simultaneously, achieving broad-spectrum control including herbicide-resistant varieties.
2Productivity
If herbicide-resistant crops are cultivated, then crop productivity is maintained, but weed control becomes more difficult
Solution Approach 1:
The patent changes the chemical parameters of the herbicide composition by incorporating multiple active ingredients with different modes of action. This allows effective control of weeds in herbicide-resistant crops by using herbicides that do not share the same resistance mechanism as the crop protection strategy.
3Adaptability or versatility
If multiple herbicides are combined to expand weed control spectrum, then control efficacy improves, but the complexity of the composition increases
Solution Approach 1:
The patent creates a universal herbicidal composition that can control a wide variety of weed species across different crop types. The multi-functional formulation addresses both broadleaf and grassy weeds, as well as herbicide-resistant varieties, through the combined action of multiple active ingredients.
