Integrated Herbicidal Composition for Broad-Spectrum Crop Pest Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods are inadequate for effectively controlling harmful organisms such as weeds, arthropods, nematodes, and plant pathogens in crop cultivation areas.
Innovation Solution
A method involving the use of ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate, combined with insecticidal, nematicidal, and fungicidal compounds, applied before, during, or after sowing crop seeds, and a foliage treatment with specific compounds during the growing period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing insecticidal, nematicidal, or fungicidal compounds are used alone, then specific harmful organisms are controlled, but comprehensive control of multiple harmful organisms (weeds, arthropods, nematodes, plant pathogens) is insufficient
Solution Approach 1:
The patent combines multiple types of pesticidal compounds (insecticidal, nematicidal, fungicidal, and herbicidal compounds) into a single integrated treatment method. This merging of different compound classes enables simultaneous control of diverse harmful organisms including weeds, arthropods, nematodes, and plant pathogens, resolving the contradiction between specific control effectiveness and broad-spectrum versatility.
Solution Approach 2:
The patent develops a universal control method that uses a combination of compounds to address multiple types of harmful organisms with a single integrated approach. The method provides multi-functional protection covering herbicide, insecticide, nematicide, and fungicide activities, allowing one treatment system to perform multiple control functions that previously required separate specialized treatments.
2Reliability
If multiple separate treatments are applied for different harmful organisms, then comprehensive control is achieved, but treatment complexity and time increase
Solution Approach 1:
The patent merges multiple separate treatment operations into a single integrated application method. By combining herbicidal, insecticidal, nematicidal, and fungicidal compounds into one treatment protocol applied at key growth stages, the method achieves comprehensive control of all harmful organism types while reducing the number of separate treatment operations, thereby simplifying the overall treatment process.
Solution Approach 2:
The patent applies the combined compound treatment at predetermined critical growth stages (seedling stage, flowering stage, and fruiting stage) before harmful organisms cause significant damage. This preliminary action at strategically chosen times prevents infestations proactively, reducing the need for multiple reactive treatments later and simplifying the overall control program.

AI summary
A herbicidal composition including ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate and a herbicide selected from the group consisting of bicyclopyrone, mesotrione, tembotrione, isoxaflutole, pyrasulfotole, topramezone, and tolpyralate. A weight ratio of ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate to the herbicide is from 1:1 to 1:42.
