French beans in greenhouse, botrytis

[womble]

When my melons died I threw in some french bean seed, to fill the gap, maybe 3 beans in the same place wasn't a brilliant idea, but I didn't expect them all to survive.

Anyway I wanted the beans to carry on after the ones outside and they did look like they were going to.

But yesterday, I saw what seemed to be botrytis on lots of different leaves and on some beans as well. Not all together, but all over the place. I've pulled all of them off.

Why have none of the tomato plants got it, yet the beans have?

Are the beans done for now and should I have pulled the whole thing up?

Womble, we had exactly the same thing last year, I had to pull the beans up in the end.

Did your tomato plants not have it either? I am suprised, they're right next to each other, I don't understand it.

A Little on the toms, but they were nearly finished. I can only put it down to the beans being so close to the damp soil and the humidity was really high. Maybe in large pots they would be better. Athough you will have to vent the polytunnel.

It could be that the species of Botrytis is specific to beans and not to tomatoes E.g. Botrytis fabae (which is prevelant throught the season) rather than Botrytis cinerea (which is usually confined to the flowering period).

Oh it could well be that then, thanks for that.

I suppose I was more thinking that if the conditions were right for the botrytis to hit the beans, I would have thought it would be for on the toms as well. Obviously not

It isn't near the floor either, all over the place.
