Hi. I just planted Drosera, but see now the begin of fungus on the surface of the spagnum and peat moss. Is it safe for the sensitive Drosera to use a fungicide? The seeds have not yet grown into seedlings. I sow them just two days ago. The fungicide I have is "Mancozeb 80%", and agricultural fingicide product from the Indian "Indofil Chemicals Company".
