Synergistic L-Glufosinate Combinations for Resistant Bidens Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides are inadequate for effectively controlling Bidens genus weeds, which are resistant and persistent, and often result in additive or antagonistic effects, phytotoxicity to crops, and resistance development.
Innovation Solution
A synergistic herbicidal combination comprising L-glufosinate, salts, or esters, and at least one additional herbicide, such as very-long-chain fatty acid inhibitor herbicides or cellulose synthesis inhibitor herbicides, is applied to control Bidens genus weeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used to control Bidens genus weeds, then weed control is attempted, but the herbicides are inadequate for resistant and persistent weeds, resulting in poor control effectiveness
Solution Approach 1:
The patent combines multiple herbicides with different modes of action (L-glufosinate, very-long-chain fatty acid inhibitor herbicides, and cellulose synthesis inhibitor herbicides) into a synergistic combination. This merging of herbicides with complementary mechanisms allows for more effective control of resistant Bidens genus weeds compared to single herbicide applications, directly addressing the inadequacy of existing herbicides while maintaining crop safety and yield potential.
2Reliability
If herbicide combinations are used to improve weed control, then synergistic effect is achieved, but phytotoxicity to crops occurs
Solution Approach 1:
The patent carefully adjusts the dosages and ratios of different herbicides in the combination to optimize synergistic effectiveness while minimizing phytotoxicity. By modifying the concentration parameters and application rates of each herbicide component, the formulation achieves enhanced weed control without causing harmful effects to crops, resolving the contradiction between control effectiveness and crop safety.
3Ease of operation
If single herbicide is applied to control weeds, then application is simple, but resistance development occurs
Solution Approach 1:
The patent employs a multi-component herbicide combination where each herbicide targets different physiological pathways in the weed (glufosinate inhibiting glutamine synthetase, VLCFA inhibitors blocking fatty acid synthesis, and cellulose synthesis inhibitors preventing cell wall formation). This merging of multiple modes of action makes it difficult for weeds to develop resistance, as simultaneous failure of multiple independent mechanisms is highly unlikely, while the combination can be applied using standard agricultural equipment and procedures.
