Introduction
Fenhexamid 98% TC is a highly effective fungicide belonging to the hydroxyanilide class, specifically developed for controlling Botrytis diseases (gray mold) in fruit and vegetable crops. It acts by inhibiting sterol biosynthesis in fungal pathogens, particularly targeting the 3-ketoreductase enzyme involved in ergosterol formation, which disrupts fungal cell membrane development and prevents pathogen growth.
As a high-purity technical material appearing as a white to off-white crystalline powder, Fenhexamid offers strong protective activity and excellent selectivity for crop safety. It is particularly effective against Botrytis cinerea, a major pathogen affecting grapes, strawberries, and vegetables worldwide.
The 98% TC technical material is intended for industrial formulation into commercial fungicide products such as water-dispersible granules (WDG), suspension concentrates (SC), and wettable powders (WP). Due to its unique mode of action and targeted disease control, Fenhexamid plays an important role in integrated disease management and resistance management programs for high-value crops.

Product Feature and Application
As a 98% technical concentrate, Fenhexamid provides strong protective fungicidal activity with excellent selectivity and crop safety. It specifically inhibits fungal sterol biosynthesis by blocking the 3-ketoreductase enzyme, preventing the development of fungal cell membranes and effectively controlling Botrytis infections.
Its primary application is the control of gray mold in grapes and strawberries, typically applied at 500–750 g/ha, depending on crop type and disease pressure. It is also widely used in vegetables such as tomatoes and cucumbers, as well as in ornamental plants.
Fenhexamid can be used alone or combined with other fungicides to expand the disease control spectrum and improve resistance management strategies.
This 98% TC technical material is intended for industrial formulation into end-use products including:
WDG (Water-Dispersible Granules)
SC (Suspension Concentrate)
WP (Wettable Powder)
Its stable physicochemical properties, good compatibility, and formulation flexibility make it an excellent raw material for modern fungicide production.
