    Would anyone have any idea what is causing this on tomato plant leaf, it was planted out into greenhouse from window sill about 10 days ago?

    Looks like fungus , perhaps blight, I'd suggest spraying with an antifungal (or potato blight spray - tomatoes and potatoes are related) asap. I'd also cut off the infected foliage and dispose of elsewhere.

  • I had the same issue which was caused by Fungus.

    I sprayed down the plants with fungusclear which resolved the issue.

    i doses the whole plant first. When it dried I removed effected leaves and a week later dosed again. Best to dose the whole plant then just the effected leaves.

    Someone told me they reckoned it was sun/heat damage and I think they are right as it has not spread at all. Am doing a lot more venting now, especially on warmer days

    Is it not early for blight?

    I found blight to leave dark patches, not white.


    I have a load of tomatoes set both in the greenhouses and hanging baskets. I notice a few of them do have discolouration and withering of leaves, particularly the lower ones.

    I carefully removed all the dogy looking foliage last year, but found when I skipped some hanging baskets in the conservatory, they got no worse anyway.

    This year I am not bothering!

    With a small number though, if I were to select a couple at random, I might think my crop was doomed!

    For some reason I seem to have problems with rooting, I'm not sure why but some tomatoes and cucumbers don't really take off like the rest. When I lift them the roots are weak and not plentiful at all.

    I simply go to one of the pots that I keep and transplant another tomato or cumber. There are often way too many seeds, so back ups are simple and fairly cost free.

    I was hit by blight last year, it was nothing like that and was in August if I recall.

    There's early and late blight types, in the damp weather we had in the spring conditions have been suitable for it but getting better during the next week.
