potato leaves turning yellow
« on: June 28, 2013, 07:09 »
Hi

Went down the allotment yesterday and noticed that two potato plants look a bit sick. The top leaves are starting to curl and the bottom leaves have turned yellow and are limp.  The bed where they are planted holds 30 potato plants.  Why are these two sick?  One is in the middle of a row, the other on the edge.  Will the rest follow ? What shall I give them to help them through?  :( :( :(


Punctuation added to make easier to read.

How long have they been in and can you take a pic as people will need to see what you mean to really help.

Yes a photo is almost a must in these circumstances, but having said that I've had a couple go that way and it's Blackleg
I'm not saying yours is, but it sounds a lot like mine.
Did it really tell you to do THAT on the packet?

There does seem a lot of Blackleg about this year, I'm losing one or 2 in each row of 16ft - 3 different varieties  :(

It's very characteristic of it. Totally random within the rows,different varieties, for no apparent reason.

I'd lay money on blackleg.

Compare it with this:

Have you pulled one up to look?

In the early stages you won't see it as it's underground.

Good point actually, if you Google "Blackleg" for photos, put "potato" in the search as well!

I have heard of blackleg on spuds but never had it on the plot, but I do this year!!  just three plants out of 140 and it is exactly the same as the picture DD put up the stems are black soft and rotten when I pulled them.
Optimism probably a gardeners best tool.

I have bought the disease control sachets as per your advice for blight DD, as I lost the lot last year.  Now I have blackleg I think (or rather my potatoes do) I've pulled up the yellow ones but they are in bags this year with garden centre compost to avoid the blight(!). Shall I spray with the disease control or will it not help with the blackleg?
