Fludioxonil
Fludioxonil (CAS: 131341-86-1), with the molecular formula C12H6F2N2O2 and a molecular weight of 248.19 g/mol, is a phenylpyrrole fungicide. It is widely used as a non-systemic agricultural chemical. Fludioxonil is applied to control a broad spectrum of fungal diseases in various crops, primarily for seed treatment and post-harvest applications. Its mode of action involves interfering with fungal cell membrane integrity.

Agricultural Fungicide
Fludioxonil is a key active ingredient in formulations designed to protect crops from fungal pathogens. It is particularly effective against seed-borne and soil-borne diseases, ensuring healthier plant establishment.
Seed Treatment
As a seed treatment, Fludioxonil provides essential protection to germinating seeds and young seedlings against a wide range of fungal infections. This application is crucial for optimising crop yields and quality.
Post-Harvest Protection
The compound is utilised to prevent fungal spoilage of harvested produce during storage and transportation. This helps extend the shelf life and maintain the marketability of agricultural products.
Analytical Standard
Fludioxonil is available as a high-purity analytical standard for use in environmental testing and quality control laboratories. It is essential for the accurate quantification of residues in food and environmental samples.
