Broad Bean Wilt Virus?
I'm new to gardening and have planted some broad beans (I'm in the southern hemisphere). They were fine for a while but now they leaves have a curled up appearance, new growth is going black and there are black spots on the leaves.
They were next to some plants (now removed) that had an aphid infestation so I sprayed the broad beans with a pyrethrum spray even though they appeared to not have any aphids.
Photos to come. Any help and advice would be appreciated.
Pictures will help! ( Hey! Didn't see them when I posted...didn't help so much...)
Black spots make me think fungus more than virus, but I have never had that issue with my favas. The beans look black when they are emerging, because of the decaying flowers sort of stuck to them. I think I'm seeing that in your second picture.
I have never had favas without aphids, eventually! What season is it there?
It's a warm autumn here. I ended up pulling the plants and disposing them. They continued to deteriorate - more blackened leaves.
I've bought some seedlings from the garden centre and plan to try them in a different patch in the garden and to be better at staying on top of aphids this time.
