Went down to the plot today,the new potato's had been looking a bit rough lately. Nearly all

the new potato's had all shrivelled up.I'm not sure if it's blight but cut all what was left of the

foliage and put into black bin bags.

I took some pics but don't know how to put them on here.

Cheers Carl

Look on the Noticeboard Carl, as there is a thread there with advice re photos (Click on the Forum Home, top right)

King Edwards looking worse for wear, desiree seem ok. Much of the lower leaves have died and gone brown along with some stalks. New green growth on top. The plants seem more leggy than past years.

Is this blight?

I have just taken all tomato plants out of allotment polytunnel with blight.  Bought home green toms, washed them, but who knows whether there be anygood.

Hope outside toms dont get it as well

If it was blight in your polytunnel the outside ones would deffo have it as well.

If they haven't you probanly had botrytis in the tunnel from inadequate ventilation

Is this blight?

Almost certainly. Brown lesions that cross the leaf veins. A light area round it. Turn the leaf over and there is mildew, more so on damp days. If the general crop looks like that it is time to cut off the tops at ground level and bag them up.

Can someone direct me to the pictures of blight and early blight please. I know that I have seen them somewhere but cannot find them with the search facility.

Do you act differently with early blight or is it a matter of cutting the foliage down immediately it is spotted? So far I have just been taking off affected leaves. Rather surprisingly it is the Sarpo that is affected.

Thanks A.

What is early blight? I am sure I read somewhere that the lesions do not cross the central vein? Is this a different disease?

[mumofstig]

Potato early blight (Target spot) symptoms may be mistaken for late blight. Early blight, Alternaria solani, however generally occurs earlier in the season (July) and spreads under warmer and drier conditions than late blight. The distinctive smaller dark brown spots, somewhat angular with concentric rings, are bounded by the leaf veins. Early blight rarely causes significant loss of yield and no treatment is necessary.

My outdoor toms succumbed to blight at the weekend  Ones in the green house OK... so far... fingers crossed 

Potatoes down the allotment also have got blight in early stages at the moment.  I've got one row that is not looking too bad so left them in for now.  Will probably get them up next week.

Hi

I know there are a lot of blight questions flying around at the moment can anyone help?

Is there such a thing as early blight on potatoes I have read a couple of things but am not sure if there is much difference between early and late - and what is the best advice is it really imperavtive to cut tops off or dig them up or can it wait a while never knowingly had blight before only discovered it once potatoes were in storage (first year nievety).

Also what is the best way to get rig of the plant tops when I do cut them down is burning the only realy way?

Some plants appear to have it others are not yet showing signs.  They have quite large brown spots

Can anyone please offer me their best advice please - thank you

I've just chopped all of mine back turned out the desiree were infected also Will wait a few weeks before lifting them to see if there is anything there.

Do I need to do anything to the soil or I can grow other stuff there as soon as the spuds are lifted?
