There's nothing available to the gardener for control of this disease, if removed promptly you can stop it spreading to other plants.

Have a look at the first link I gave for fuller information.

Mine have some yellow leaves which seem a bit lifeless, but the leaves aren't curled up and the stems are green and healthy, so All I'm doing is taking the leaves which are most wilted off.

That link was an interesting read DD !  Joined RHS at same time

As DD said in previous post you have to pull one to see, on mine it was black at the very end of the root and the seed potato was like mush and also black, better safe than sorry as this can spread to the others i lost 2 plants but glad i dug them up.

I've also lost a few spud plants to this this year. Thought it must have been where I brought the spuds from but if we're all having a problem then it must be because last year was so bad

I think black leg is on a massive increase this year compared to last!

Maybe it's in the seed potatoes, it can't be in the soil because I'm growing mine in commercial compost in new potato sacks this year in an attempt to actually get to eat my first potato!  Last year and the year before the blight got them,  this year I have pulled out 2 because of the blackleg,  I do hope I get some of them!

Thanks to DD I now know about a new (to me) disease of spuds.  The picture in the RHS link looked exactly like one of my plants.  So I have rushed up to the plot and dug it out and disposed of it - hopefully saving the rest of my spuds.   It didn't half smell horrible.  (These were new certified seed potatoes this year from a good supplier, and in new ground that hasn't grown spuds for at least 5 years.)

The good news is that I can tick off another item in Hessayon's book of plant diseases and pests.
I've almost ticked off the whole book.   Is there a prize for ticking them all

Duly merged!

Just want to add my thanks for this - I've had one plant going 'off' and the symptoms were prescribed perfectly so  have been down to remove it and a neighbouring plant.  The badly affected plant had gone black at the bottom of stem but had not gone further.  Hope that's it now but ......... not really sure that I've got away with it yet
