Possible Potato Virus

[jasyk34]

Anyone out there grow potatoes regularly and can identify what has gone wrong with my crop ?

I have inserted 2 images of the problem. basically the leaves have not opened out. They are still rolled up and havent opened out. They have been like this for over one month and I dont think that they are going to open. Some of the potatoes leaves on other plants have opened out ok.

Any ideas ???

That looks like the effects of contaminated manure - aminopyralid I think it is called. What have you planted them in?

That is worrying. I did plant them into manured land. I had planted these in work not at home but used manure from the farm. Will have to check what the farmers have used if anything on the grazing area.

Jeanied, many thanks. That looks like the problem. Googled aminopyralid and found a link on the following site (posting just in case it benefits anyone else with a similar problem) Contaminated Manure Aminopyralid Update

Jaysk34 here is a picture from an allotment website of potatoes affected by contaminated manure.

Certainly appears to be the problem. Not good I'm afraid!

I'm a bit confused (nowt new there then) looking at these pictures they appear to be very similar to a problem that has shown on the allotment with potatoes - BUT - I have 6 raised beds with six different varieties of potato in them, all with the same manure in, and yet only the Anya bed has been affected, the rest are looking green and healthy. Others on the allotment have had all their potatoes hit, but they do use a common source for their manure, whilst I went to an independent source.

The Anya never really took off from the start, so am thinking the other potatoes are going to be okay, as they have grown strongly - is there some other virus or disease that may have been in the Anya tubers (mind I did buy certified stock) that would manifest itself in a similar way to the manure problem?

I had poor results from ANYA last year everything else all around them grew brilliant but not the anya, one root I dug looked like a handful of baby mice and they were dug as a second early

My Anya are way behind every other variety ... all planted at the same time

The Anyas definitely have curly leaves and appear to have fern like growth (although only very small amounts) that the manure problems seem to bring, which makes it so puzzling. One guy on the allotments is calling DEFRA. I'm just seeing what happens, if they fail I've always got another 5 beds, which look like they're doing okay. If I find out anymore I'll let you all know.

Is it possible that the seed potatoes were affected before you bought them? We had a similar problem on our site last year but the plot holder hadn't kept the reference code on his packaging - who does - and so we couldn't follow this up.

WE found that volunteer potatoes growing from affected potatoes di have the symptoms of contamiantion and I also know of one victim who collected beans from contamianted plants and sowed them. The all grew showing the symptoms too. Plant materials from affected plants shouldn't be composted as this perpetuates the problem
