It is a unique combination of contact and systemic fungicide. Its contact part is Zineb which is a broad-spectrum fungicide with protective action. It is fungitoxic when exposed to air and is converted to an isothiocyanate, which inactivates the sulphahydral (SH) groups in enzymes of fungi. Some times the metals are exchanged between Zineb and enzymes of fungi, thus causing disturbance in fungal enzyme functioning. It acts by blocking the metabolism of pathogenic fungus at cellular level, at several stages of Krebs Cycle.
Other partner in this combination is Hexaconazole which is a unique highly systemic triazole fungicide, acting as protective, curative and eradicant with strong antisporulant and translaminar action. It is a potent ergosterol biosynthesis inhibitor. Ergosterol, a principal sterol in most fungi is an indispensable component in the membrane structures
