Spots on potato tuber leaves

[dunlop3551]

Hi there im new to the site my names steve

I have 2 diffrent crops of potatos in the green house

Been in there now for around 8 weeks maybe 9

Today i noticed the leaves have bubbly yellow spots on and some curling up

Any idea on what this is

Many thanks

Don't know where you are, but maybe too warm and wet in the greenhouse?

Hi im in wales

The green house is not getting over 10c most days

[dunlop3551]

Is it anything to worry about

[Potstubsdustbins]

I take it their in containers? If so have you fed them at all and if so what with.

Hi Colin

There in a 3 ft deep bed built into the green house

No i havent fed them the soil did have blood fish and bone etc put in

They where all healthy intill i checked today other than them going a little to high

[Potstubsdustbins]

In that case it may be bad news, it could be a virus. Have you noticed any aphids about at all.

No cant say i have but will double check
Is it worth checking whats going on under the soil

[Potstubsdustbins]

I wouldn't have thought so. Are they new pots or main crop?

Main Crop

Aaran pilot was the one

[Potstubsdustbins]

Arran pilot is a first early and supposedly disease resistant.

You will only be looking at about 10/12 weeks in the ground before harvest. At this stage I would give them a high potash feed (Tomorite) and see how they go. Thers a good chance you will still get a harvest.

I would guess at Potato Mosaic Virus

I would guess at Potato Mosaic Virus

That was my leaning hence the question about aphids. But as there is no treatment I thought feed and see might be the way to go.

This virus can also come with the seed potatoes where did you get your seed?

Got the Seeds from Wilkinsons

Is that virus serious

Yep,I would go along with you there Colin,particularly as (apparently) if it were a few degrees warmer the spots would be un-noticable & there should be no major yield loss ..... http://www.plantprotection.hu/modulo...mosaic_pot.htm
