Synergistic Herbicidal Composition for Resistant Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides are inadequate in effectively controlling undesirable vegetation in agriculture, particularly in areas with herbicide-resistant weeds, and there is a need for improved compositions and methods that enhance crop tolerance in 2,4-D and glufosinate-tolerant crops.
Innovation Solution
A composition containing synergistic herbicidally effective amounts of the choline salt of 2,4-dichlorophenoxyacetic acid (2,4-D-choline) and the ammonium salt of 2-amino-4-(hydroxymethylphosphinyl)butanoic acid (glufosinate) is used, which can be applied alone or with other herbicides, to control weeds and improve crop tolerance in soybeans, corn, and cotton.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single herbicides are used, then application simplicity is maintained, but weed control effectiveness deteriorates due to herbicide-resistant weeds
Solution Approach 1:
The patent combines two different herbicides (2,4-D-choline and glufosinate) into a single composition to achieve synergistic weed control. This merging of multiple active ingredients resolves the contradiction by providing enhanced effectiveness against herbicide-resistant weeds while maintaining a practical single-composition application system.
Solution Approach 2:
The invention uses a composite herbicidal composition containing 2,4-D-choline and glufosinate in specific ratios. This composite material approach allows the combination of different modes of action to overcome herbicide resistance, improving reliability without requiring complex multi-step application procedures.
2Reliability
If higher herbicide doses are applied, then weed control effectiveness improves, but crop injury increases
Solution Approach 1:
The patent optimizes the concentration ratios of 2,4-D-choline and glufosinate in the composition to achieve synergistic effects at lower total doses. By changing the parametric composition (specific ratios of active ingredients), the invention maintains high weed control effectiveness while reducing overall herbicide load and associated crop injury.
Solution Approach 2:
The composition acts as an intermediary system that mediates between weed control requirements and crop safety. The synergistic combination allows each active ingredient to work at optimized concentrations, achieving effective weed control while the formulation itself protects against excessive crop injury through balanced dosing.
3Reliability
If 2,4-D and glufosinate are used separately, then individual herbicide mechanisms are maintained, but synergistic effects are lost
Solution Approach 1:
The patent merges 2,4-D-choline and glufosinate into a single pre-mixed composition, capturing their synergistic effects while simplifying application to a single step. This resolves the contradiction by maintaining both individual mechanisms of action in a unified formulation that delivers enhanced effectiveness without requiring separate application procedures.

AI summary
Provided herein are herbicidal compositions comprising a mixture comprising (a) a choline salt of 2,4-dichlorophenoxyacetic acid (2,4-D-choline) and (b) a salt of 2-amino-4-(hydroxymethylphosphinyl) butanoic acid (glufosinate). The compositions provide synergistic weed control of undesirable vegetation and improved crop tolerance in 2,4-D- and glufosinate-tolerant soybeans, corn, or cotton. The compositions also provide synergistic weed control of undesirable vegetation in areas including, but not limited to, non-crop, perennial crop, fruiting crop, and plantation crop areas.
