Mode of Action
It is mixture of two fungicides – Mancozeb and Metalaxyl. The partner mancozeb acts by its contact action. Mancozeb is fungitoxic when exposed to air. It is converted to an isothiocyanate, which inactivates the sulphahydral (SH) groups in enzymes of fungi. Sometimes the metals are exchanged between mancozeb and enzymes of fungi, thus causing disturbance in fungal enzyme functioning. Other partner Metalaxyl inhibits protein synthesis, growth and reproduction in fungi.
