Do any fungicides kill plant fungi

    Would like a straight answer is there any fungicides that kill fungi on plants rather than act as preventive measure as I have smallish black spots on the leaves and stems of some of my shrubs and am wondering can they recover. Didn't have a chance to spray them with bordeux as it been raining non stop and it would have been washed off instantly thus doing nothing. Is there any home made ones that can help kill the fungus.

    Regardless of the weather there is always ample time to spray, saying you didn't have time is just an excuse, also you have to remember fungal spores are everywhere and given the right conditions they will grow and keep coming back, there is no long term definitive solution (thank God, because without ithemthe natural world as we know it wouldn't exist) and you'll have to keep treating it forever, that's the nature of fungi.
    Although you could lighten your workload by only having disease resistant plants.

    Cold chamomile tea generally works on the kind of fungus caused by damping-off (paired, obviously, with a bit more heat and less damp in the seedlings' environment). You could try it for your blackspot.

    Are you sure it's a fungus? Spots can be caused by many things and if they are on a number of unrelated plants then it's unlikely to be a fungus. Anyhow, feeding plants and making sure they are strong growing is usually the best defence with regard to plant problems.
    BTW gardening rarely throws up straight answers! ;)
