Rubigon-D is a broad-spectrum systemic fungicide belonging to the DMI (Demethylation Inhibitor) group, formulated with Difenoconazole 25% EC. It provides strong internal protection by moving within plant tissues and controlling fungal growth at multiple stages of development.

It is highly effective against foliar diseases such as powdery mildew, leaf spots, scab, and anthracnose. Due to its systemic nature, Rubigon-D ensures both preventive and curative action, helping maintain healthy foliage and improving overall crop quality and yield.

The product is widely used in integrated disease management programs due to its reliable performance, long duration of control, and consistent field results across diverse climatic conditions.
