Botrytis

BacktoBasics · « **on:** December 06, 2012, 07:53 »

Hi all,

this year was a difficult year i that I didn't spend anywhere near enough time in the garden. I ended up with a big work contract that that took over almost completely. We did get some crops this year and for my first year it wasn't bad. Unfortunately one of the side effects of my neglect has been a greenhouse with 30 tomato plants ( or thereabouts ) covered in that horrible grey mould we call botryosis. Now I know how to dispose of the infected plants - they will be incinerated. My problem is that the base of my greenhouse is gravel and sand and there will inevitably be a host of botryosis spores there. What can I spray on the ground or indeed around the whole inside of the greenhouse to kill off the spores?

Thanks

A lot of us got Botrytis in the greenhouse this year, so don't feel too bad about it.

Jeyes fluid can be used for sterilising the greenhouse and sand ( it's not licensed for soil though)

and/or you could light a sulphur candle.

Same problem here.

I found that it could be kept under control to a large extent by removing any infected leaves immediately. This meant that the tomato plants had few leaves on low down, but it did not seem to reduce the crop.
Good ventillation is also necessary.

Thanks for the replies. So the sulphur candles kill off the spores do they? Where can I get them locally?

These tomato plants were all grown in growbags. Ordinarily I would chuck the spent compost into another bed - brassica, root, courgette/squashes, beans. Is this a bad idea?

They claim to kill fungal spores - how deep the vapour can penetrate into the soil is another matter so the effectiveness may partly depend on whether the soil has been turned over and therefore buried some of the overwintering spores.

I wouldn't worry too much about whether I'd achieved 100% sterility though - like blight the spores will at some point be in the air anyway and growing strong, well-spaced and ventilated plants is still the best defence (weather permitting!)

I certainly chuck my spent compost on the garden, although I would try to avoid transferring possible diseases or pests over to the same or related plants (in the case of tomatoes that would be other solanaceae, including potatoes.)
