Preventing fungus attack

The potatoes are really pretty now. About two years ago we weren't cautious and the potatoes foliage was attacked by the mildew and all the harvest was burnt.
This year we are being very cautious. We already have give them twice the bordeaux mixture (portuguese "calda bordalesa") which is a natural fungicide, made from copper sulphate and slaked lime, to prevent the attack of fungus, specially the mildew.
