Fungi on melon leaves

[gonk]

I am on my second/3rd melon plants after throwing the first out due to fungi on the leaves. I have read that you need to get some fungi spray to cure them but everywhere Ive looked the stuff is all for ornemental plants and not veg. Surely there must be more of a home cure solution rather than buying chemicals? Any suggestions as shame to chuck 2 more good plants that the kids grew from seed?

You sure it is fungi?

Have you got a photo?

Mould/fungi, not hundred percent sure how best to explain but it killed the last melon and butternut plant I had in the greenhouse. Nothing else being effected. Will try and post a pic over the weekend.
