Blight on main crop potatoes

[maverick451]

Hi Guys

I have what I think is some blight on my main crop potatoes, at the moment it is only the odd leave here and there, how should I deal with this? should I leave them for a while and take off just the infected areas or should I cut my losses and chop them down.

Sorry to say it does look like it. If it were me I would. It my losses chop the tops off then leave it at least two weeks before lifting them. With any luck the spores will die and not affect the tubers.

Agree with Roitlet. You are better harvesting what you can, even if the potatoes still have potentially a few more growing weeks, than risking the whole lot. It spreads alarmingly quickly but at this early stage I'd be surprised if it was on the tubers already.

I'd do the same.

I agree with the others. You don't usualy just get a touch of blight, even at the stage yours are at the moment the disease is most likely already spreading through the others.

Thanks guys

Disappointingly those affected include Sarpo Mira (or were sold to me as sarpos)

I'm not sure that Sarpo potatoes don't get blight, they are resistant. This is not the same thing. Probably they will get it but it won't affect the plants and crop as badly. I haven't had blight when growing them so I can't say from experience.

Some interesting info here: Sarpo Mira, DIVERSITY WEBSITE, blight proof potato?

How long have you had discoloured leaves? Blight acts very quickly a matter of a few short days.
