[Mark's Sussex Allotment]

Nearly all potatoes got blight in Littlehampton, started about 3 weeks ago.

All we have left is brown stalks all over the place.

It looks like October!

Was away for a week at the beginning of June and came back to find some very poorly tomatoes at my daughters. YO26 postcode - wasnt entirely sure if it was blight r a bacterial stem rot but pulled them all up except one small bush tomato which appears to have escaped.   Potatoes on friends nearby allotments also YO26  look unaffected

[Beetie]

Is it....?

Is it....?

Hey up its my spuds, looks like mine and mine have it 

[devonbarmygardener]

My Lady C's look a bit like that too

DBG that may not be blight. The complete leaf we can see at the front is discoloured in lines between the veins which I would say is magnesium deficiency. The other black spots may also be magnesium deficiency. They could be early blight but I would expect to see rings, it is alternatively called target blight for that reason. Early blight usually does little harm. The spots do not cross veins. Late blight crosses the veins and the lesions are usually bigger and more untidy.

Not late blight for me either DBG.

[Aunt Sally]

Is it....?

No... It's Early Blight (target spot).  It won't affect the tubers.

Went to plot tonight and plot neighbours diggig up all their kestrel as they say they have blight. Mine are kestrel also but look fine so suppose had better keep check on them and dig up quickly if see some odd leaves!

[mumofstig]

If it is blight don't dig them up quickly - cut the tops off and leave the potatoes underground for a fortnight, they've got less chance of getting live blight spores on the tubers when you dig them up then, than if you do it straight away.

RHS advice

•When infection levels reach about 25 percent of leaves affected or marks appear on stems cut off foliage (haulm) severing the stalks near soil level and raking up debris. When the skin on tubers has hardened, after about two weeks, the tubers are dug up and stored.

Thanks mum. Will keep check on them and do that if any problems

[bravemurphy]

We have it now on our plot so I would say a day or two and mine will be chopped 

[archibtbm]

Blight has hit our site, a few plots mine included.  We have all cut the tops off and left them in the ground.... so very annoying

Hi guys... have I got Blight?

[mjpalin]

Blight on the potatoes here in Tadley, looks like a few plots have it. Tops have been taken off the salads and 2nd earlies tonight. The couple of maincrop that survived the flooding are Sarpo's so hoping they'll be ok.

Only growing toms in the greenhouses so hope they have a bit more protection, but will start spraying them tomorrow to (hopefully) give a bit of extra resistance.
