Description

Fluridone is a selective systemic herbicide belonging to the pyridinone chemical class, widely recognized for its long-lasting pre- and post-emergent control of invasive aquatic and terrestrial weeds. Its primary value lies in its ability to inhibit carotenoid biosynthesis, effectively managing nuisance vegetation in sensitive environments without harming many non-target species. This compound is essential for professionals in aquatic vegetation management, industrial site maintenance, and certain agricultural sectors requiring persistent, broad-spectrum weed control.

Application

• Aquatic Weed Control: Primary use for managing submerged and floating weeds like hydrilla, Eurasian watermilfoil, and pondweeds in lakes, reservoirs, irrigation canals, and decorative ponds.
• Industrial Vegetation Management: Control of unwanted vegetation on non-crop areas such as rights-of-way, utility substations, and around industrial perimeters.
• Ornamental and Turf Management: Selective control of specific weed species in managed turfgrass and ornamental landscapes under professional application guidelines.
• Research & Development: Used as a biochemical standard and tool in plant physiology research studying pigment biosynthesis and herbicide mode of action.
• Formulation Intermediate: Serves as the active ingredient in the manufacture of professional-grade liquid and granular herbicide formulations.

Quality Control

Our Fluridone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including identity confirmation, assay, and impurity profiling, to meet technical-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from heat, sparks, and open flame.
