Rust on Broad beans
« on: August 14, 2012, 21:38 »
I have never seen this before but I have had a rust coloured dust on my broad bean leaves which absolutely covers you when picking. As I am not sure what this is I have stripped the stems of the pods and pulled  everything up and burnt them, The broad beans themselves are fine and have a lovely flavour although some of the pods are discoloured. Has anyone else had this problem?

It's probably chocolate spot.  I get it this time of year so usually plan to have mine sown early enough to avoid it.

Thank you I haven't heard of that. Perhaps it's because everything is late this year and too much rain!

Chocolate spot that we have had is black marks and dots on the leaves, stems and pods, rather than orange dust  :unsure: :unsure:

Here is a link which shows both chocolate spot and broad bean rust: it does say this is quite rare and a late season problem, so I'm guessing this could be what you have.

Burning them all was definitely the right thing to do Susannah  :)

Hope that helps

Regardless of whether you have chocolate spot or bean rust you've done the right thing in destroying the foliage as it's the same advice for both diseases.

We have chocolate spot on ours this year too but the beans themselves are just fine. We hope to finish harvesting them this weekend after which the foliage will be destroyed.

Does anyone know if it will be a good idea to dig in the roots as I usually do (as they provided a source of nitrogen) or should these come out too?

Thank you for all your replies, I did google it last night and it certainly was chocolate spot.
I have been growing my own now for over 30 years and my parents before me so a good 60 years of growing broad beans and I have never come across this problem before!

You've had a lucky escape then for all those years, as it is quite a common disease  :nowink:
