Zeb m-45 (mancozeb 75% wp) is a contact fungicide of the dithiocarbamate group, which checks the growth of fungus and the spread of diseases. It reduces the activity of enzymes in fungus which in turn reduces the energy production and finally results in the death of the fungus.
Mode of action: it is a broad-spectrum fungicide with protective action. The product is fungi toxic 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 a disturbance in fungal enzyme functioning.
Crops: paddy, wheat, potato, tomato, groundnut, grapes, chili, banana.
Disease: blast, brown & black rust, early & late blight, leaf spot, tikka, downy mildew, fruit rot, Sigatoka leaf spot.
Dosage: 50-60gm in 15ltr of water. 600-800gm in 180-200ltr of water per acre.
