Is It Blight?

[SarzWix]

That's all Bordeaux mixture is - a preventative. Once you have it, it can't get rid of it, unfortunately

Got a couple more questions...
I've cut off all the green tomatoes, bagged up the foliage and any affected tomatoes ready for burning.
Once this has all been burnt, can I use the ash on the compost heap? Logic says yes, but just in case I thought I'd better ask for a definitive-ish answer.
And..I've pulled up the rootballs of the tomatoes [there was no blight up to the stem at the bottom, only starting about halfway up], what do i do with these? Can they be composted, or shall I landfill/recycle dump them?

[taff]

and more questions....sorry....
I cut the potato foliage off from teh bucket that was next to the bed with blight as I saw it on one set of leaves at the end of a stalk. The usual thing [I read] is to leave them in the compost/earth for 3 weeks to avoid blight getting into the soil but...
If the blight was already on the tomatoes, won't it be in the soil anyway as spores? SO if this si the case, can I empty the potato container into this bed and just not grow any toms or spuds in it? And roughly how long do you think I can't grow toms in it? I do have 8 beds so far, so it'll take quite a few years before I'm back to that one, but just asking....I worry about stuff sometimes

Errrrr.... I dunno taff... The bed I had blight on last year won't come round in my rotation for about another 4 years! I guess you could spread the spent copmpost on one of your beds if it's going to be a long rotation, and you're absolutely certain that there's no volunteer spuds in there (even teeny tiny ones )
I'm not sure about the root balls... Soz! Hopefully someone more knowledgable will be along soon.

thanks Sarz

It's just like Uncle Buck...What's your record for consecutive questions in a row?

Well - blight again! For a couple of days I'd been taking the odd classic blight leaf off the potatoes, every day. Friday night I thought I was winning, only a couple of leaves to take off. 12 hours later every leaf in the bed was infected, I just stood there looking in disbelief. Cut every plant off. I only had first and second earlies and even the seconds had flowered so the crop is looking good. Now I'm snipping away at suspect leaves on the tomatoes in the greenhouse, hopefully I'm just paranoid now!
Although I'm pretty sure my runner beans have halo blight - apparently more common in wet seasons - that would be right!

Last week a work colleague, growing potatoes for the first time, asked what blight looked like. I sealed an infected leaf in a poly bag and showed her. She decided to take it home and show her friend (I warned her not to open the bag). By the time she'd got home the leaf was completely black!

Bob Flowerdew reckons that you can put the blighted foliage on your compost heap because the spores only survive on living plant material. He's an expert but, I confess, mine get burned. Paranoia rules OK.

You know how blight develops over time on tomato fruits, not always hitting them all at once?

What happens if I cook with the tomatoes or use them for green chutney? Will the food go off?

[zazen999]

Blight here too...toms at the lottie...found a couple of dodgy leaves on tuesday afternoon, sprayed late tuesday afternoon and a couple of toms had already gone blackish - so I've taken all the ones big enough off and its been raining ever since so I don't hold out much hope.

Gonna cut all the potato foliage back this weekend...

Hi I was looking to buy a blight test kit and found it in harrod horticultural website but expensive for only 2 tests! so looked up potatoes on gyo website and got the web address for JB potatoes and they are selling the 2 tests for roughly half the price but also have a kit with 5 tests in it for the same price as harrod horticultural is selling their 2 test kit! Just though I would let you all know! They also have a large range of xmas potatoes for sale - defo worth a look!

Blight on my plot, too.

I've cut all my potato foliage down to ground level.

I also have the early stages of it on my toms at home. I have one tom with a small brown spot on it. Is this a symptom of blight?

[taff]

I just made a batch of chutney with the green tomatoes that i salvaged this week, it all looks ok so far.

Have a look here, it'll give you an idea of the colour it is on a green tomato.I could show on the top, on the sie, anywhere really, and starts off as a small brownish spot. There may be dark brown/black patches on the stems, or on the truss stems, or black sooty-looking spots on the leaves.

I have lost all my toms to blight, pulled them up last week. :-(

Please don't tell me this is tomato blight. (Photo's).

Hello all.

I hope I've put this in the right section.

I've never grown a thing in my life but I was given 6 tomato plants and have planted them in two grow bags. They are outside.

I have nursed them and looked at the wonderful and numerous tomatoes growing. But yesturday I noticed blemishes on the leaves.

I studied the sticky on tomato blight and have examined all the pictures but I still can't decide if it is blight.

I'm hoping that someone can confirm if it is. I have included some photo's. Hopefully they are clear enough for you to see.









These are taken from three plants that are in one grow bag, the other three seem ok at the moment.

I have a few more photo's if needed and I can take more if required.

Regards.

I'd say it isn't blight, more like the leaves have got wet and the sun has burned them
