When to give up on outdoor tomatoes due to blight
I'm seeing the first signs of blight.
A few dark patches on stems, a few marked leaves, a few marked tomatoes. Mostly the tomatoes seem fine, there is still a large crop and they are still ripening. What is the best way to prolong cropping, and how long do you think I can get away with it? Cheers Dave R |

Cheers Dave R I'm going to pick the last of my outdoor toms tomorrow. This is the first year without blight for over 10 years. I've had 2 or 3 Blight Watch warning messages but no blight here.

If they aren't Blight resistant varieties then a couple of days before the plants turn totally black and collapse IME, even if Blight resistant they are on the slippery slope and will only last another week or two. Even the tomatoes that look fine will probably have blight and it will often show after you pick them. Personally I'd pick off everything I think will ripen and get rid of the rest and the plants. Bordeaux Mixture or similar is your friend, start to spray as soon as rain is forecast in July and before it happens, and then again every couple of weeks if it remains damp/humid. That way the blight should not get a hold. -- Regards. Bob Hobden. Posted to this Newsgroup from the W of London, UK |

Cheers Dave R Bonfire NOW. I have read that the plants can be composted but not the fruits. I'm not convinced. Anything from my plantation that looks dodgey will be sent off site for destruction, ASAP. Regards JonH |

I understood it was OK to compost all of the plant and the unripe fruit as the spores can only survive on living tissue. What is important is that you remove all infected potatoes from your plot which will harbour the spores over winter. -- Regards. Bob Hobden. Posted to this Newsgroup from the W of London, UK |

Yes, I'm working on the spuds. The buggers keep hiding from me, I've got Volunteeers springing up left right and centre. Apart from those early ones in bins in the greenhouse I've given up on spuds - for the moment. Next year maybe, when I've cleared another patch of Bindweed/Creeping Cinqufoil/Whatever pernicious weed comes to mind I may take a different view. Regards JonH |

Cheers Dave R If you're in the US, there is a really awesome environmentally friendly product called OxiDate RTS that we sell. Not sure how much you need covered but it's labeled to cover up to 12,000 sq ft. It fights both early and late blight.

Cheers Dave R Are you sure it is blight? I think it could be end of season blossom end rot(or whatever they call it) Outdoor tomatoes this year have had to put up with some very low night time temperatures. It is surely normal at this time of year to have a few dark patches on stems, and few marked leaves. I have all of this, but, it IS October after all IMO, expected. Prolong them by picking the whole vine, before frost and put them in a dark place to ripen. Some people say put them in a sunny position, but dark works for me. Baz |

Dark patches on stems. Dark patches on shrivelled leaves. Brown areas on small fruit. General wilting. Temperature is fine - 18C - and without blight I would expect cropping to continue until the first frost. Very sheltered and sunny area. I need to clear all of the damaged stuff out a.s.a.p. This is in my back garden, not down at the allotment. Cheers Dave R |

The EU and our own Defra demand all sorts of tests before a product can be marketed, it is not sufficient that it is tested, approved and sold in the USA. These tests cost £100,000+ which makes it uneconomic even for the major chemical companies when they consider the potential sales to private gardeners. Which is why we amateur growers now have very few chemicals with which to treat diseases/pests over here, even Bordeaux Mixture is shortly to be banned. The Government keep saying people should grow their own food but they make it increasingly difficult. -- Regards. Bob Hobden. Posted to this Newsgroup from the W of London, UK |

IME they often hold out a lot longer than that. Mine on the allotment (all volunteers) started showing signs weeks ago, and I only gave in and pulled them all today. At the time they were all totally green, now I have a huge tray of green and the occasional red, and a good few on the turn which I think will make it. (it seems to be the round ones that go blighty later from green, the other shapes seem to get blight early on and once they're picked if they haven't got it, they won't. Of course, no idea what any of the varieties are - one is long and sausage shaped, and not at all like anything I've ever grown in the past!) |
