MATCO 8-64 FUNGICIDE
Technical Name: Metalaxyl 8% WP + Mancozeb 64%
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.
Dosage: 2 gm/litre and 400 gm/acre
General application rate for foliar spray is 200 – 250 gms / 100 liter of water. Water volume ranges between 500 500 to 1000 liters per hectare based upon crop type and crop stage.
