Title: Blight
Post by: Diana on July 10, 2006, 13:48:41
Anyone else got blighted potatoes yet? My Swift went down about a month ago (I suspect bad seed, as, when I dug some up, the seed was total mush).

Now my others are ailing

You sure it was blight? would have thought that was a bit early. Maybe they were just finished growing and foliage died back? Did you get any potatoes at all? Sometimes the seed potato used does rot, thats nothing to worry about usually.

Thanks Jenny, yes I have still got a crop, but some of the tubers are still very small.

I'm pretty sure it was (and is) blight - lots of tiny black dots that grew larger and the rest of the leaf went yellow.

Put the diseased stuff in the bin + when it was emptied there was a foul sludge at the bottom

Would love to know it's not bight (she said ever so hopefully)


Having said that, it looked more like this:

RC, what's die back?

What's it look like + what causes it?

Soft rot in the tubers is far more likely at this time of year, but one of the very early varieites (swift/rocket) is noted for being very susceptible to tuber blight!

Sorry - just when the plant has finished doing its thing and dies back.
