Fenamidone 10% + Mancozeb 50% w/w WG (60 WG)

Sectin 60 WG is a combination fungicide containing Fenamidone and Mancozeb, thereby giving dual contact and systemic activity against Phycomycetes diseases, late blight of potato and tomato, downy mildew of grapes and vegetables and Pythium spp. It also controls nonphycomycetes leaf spot diseases like Alternaria and Mycosphaerella.


Fenamidone inhibits mitochondrial respiration by blocking electron transport at ubihydroquinone: cytochrome-c-oxidoreductase (Complex III). Sectin is a protectant and curative fungicide. Mancozeb acts as non-specific thiol reactant, inhibiting respiration. It is a contact fungicide with protective action.
