Introduction
Fludioxonil 98% TC is a highly effective non-systemic phenylpyrrole fungicide widely used for the control of fungal diseases in fruits, vegetables, and seed treatment applications. It acts by interfering with the osmotic signal transduction pathway in fungal cells, disrupting fungal growth and preventing pathogen development.
As a high-purity technical material appearing as a white to off-white crystalline powder, Fludioxonil provides strong protective activity and long residual control. It is particularly effective against Botrytis, Fusarium, and Rhizoctonia species, which are responsible for major crop losses worldwide.
The 98% TC technical material is designed for industrial formulation into commercial fungicide products such as water-dispersible granules (WDG), suspension concentrates (SC), wettable powders (WP), and seed treatment formulations (FS). Due to its broad-spectrum activity and reliable disease control, Fludioxonil is widely used in integrated disease management and resistance management programs.

Product Feature and Application
As a 98% technical concentrate, Fludioxonil provides strong protective fungicidal activity with long residual efficacy. It works by disrupting the fungal osmotic signal transduction system, leading to abnormal fungal cell development and inhibition of pathogen growth.
Fludioxonil is widely used for gray mold control in fruits and vegetables and for seed treatment applications in cereals and field crops. Typical application rates vary depending on crop type and disease pressure.
The product can be used alone or in combination with other fungicides to expand the disease control spectrum and support resistance management strategies.
This 98% TC technical material is suitable for manufacturing the following formulations:
- WDG (Water-Dispersible Granules)
- SC (Suspension Concentrate)
- WP (Wettable Powder)
- FS (Flowable Concentrate for Seed Treatment)
Its excellent chemical stability and compatibility make it an ideal raw material for modern fungicide production.
