Fluroxypyr and Halosulfuron-Methyl Synergistic Herbicide Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicides often require higher application rates to achieve effective weed control, and there is a need for synergistic combinations that can control a broad spectrum of weeds, particularly in crops like rice and cereals, while minimizing harm to the crops themselves.
Innovation Solution
A synergistic herbicidal composition of fluroxypyr and halosulfuron-methyl, an ALS inhibitor, which when combined, exhibit a synergistic effect at lower application rates than individual use, controlling weeds such as barnyardgrass, Chinese sprangletop, and yellow nutsedge, and can be used with other herbicides and adjuvants to enhance weed control efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher application rates of current herbicides are used to achieve effective weed control, then weed control efficacy is improved, but crop harm and environmental impact increase
Solution Approach 1:
The patent combines fluroxypyr (a growth regulator herbicide) and halosulfuron-methyl (an ALS inhibitor) into a synergistic mixture. This merging of two different herbicide modes of action achieves enhanced weed control efficacy at lower application rates, thereby reducing crop harm while maintaining reliable weed control.
Solution Approach 2:
The invention creates a composite herbicidal composition containing fluroxypyr and halosulfuron-methyl in specific ratios. This composite material leverages the complementary mechanisms of both herbicides to achieve synergistic effects, improving reliability of weed control while reducing the harmful factors associated with higher single-herbicide application rates.
2Reliability
If higher application rates of herbicides are used to control a broad spectrum of weeds, then weed control efficacy is improved, but application cost and environmental impact increase
Solution Approach 1:
The patent merges fluroxypyr and halosulfuron-methyl into a synergistic combination that broadens the spectrum of controlled weeds including grassy weeds, broadleaf weeds, and sedges. This merging allows effective broad-spectrum control at lower total application rates, reducing the quantity of substance required compared to using single herbicides at higher rates.
Solution Approach 2:
The invention changes the parameter of application rate by utilizing the synergistic interaction between the two herbicides. The combination enables achieving the same or better broad-spectrum weed control efficacy at lower application rates, thereby reducing the quantity of substance needed while maintaining reliable control.
3Ease of operation
If single herbicides are used to maintain simplicity of application, then ease of operation is improved, but weed control efficacy against diverse weeds is insufficient
Solution Approach 1:
The patent combines two herbicides with different modes of action into a single synergistic formulation. This merging provides broad-spectrum weed control efficacy against diverse weeds while maintaining the ease of operation of a single application, eliminating the need for multiple separate herbicide applications.
Solution Approach 2:
The synergistic herbicidal composition achieves multi-functionality by controlling multiple types of weeds (grassy weeds, broadleaf weeds, sedges) with a single application. This universal formulation maintains ease of operation while significantly improving weed control efficacy across diverse weed spectra.

AI summary
An herbicidal synergistic composition containing (a) fluroxypyr and (b) an ALS inhibitor herbicide, in which the ALS inhibitor herbicide is halosulfuron-methyl, imazamox or imazethapyr, provides improved post-emergence weed control in rice, cereal and grain crops, pastures, rangelands, IVM and turf.
