Prochloraz 45 EC is an Emulsifiable Concentrate fungicide containing 450 grams per liter of the active ingredient Prochloraz, a broad-spectrum imidazole fungicide.
It is used extensively in agriculture, horticulture, field crops, and fruit crops to control a wide variety of fungal diseases.

Prochloraz works by inhibiting ergosterol biosynthesis in fungal cell membranes—this disrupts fungal growth, reproduction, and infection processes.

It belongs to the Imidazole chemical class and is categorized under FRAC Group 3 (DMI – Demethylation Inhibitors).
