Raspberry - Virus ?

Hi,

Have a row of Polka Autumn fruiting Rasps now in their 3rd year but this plant looking wrong in that most of the new shoots are just staying very small and not growing on like the shoot on the right of the picture or the rest of the row.

Is this typical of a Virus that could spread or just something gone wrong with this one plant ?

 

I think I'd remove that particular plant, which looks like it is infected with a virus. Most viruses are transmitted via aphids on raspberry plants, so getting rid would help stop it spreading, although some viruses are transmitted via soil nematodes.

 

I had some autumn fruiting raspberries years ago and one year the crop just dropped off, and it didn't recover so I got rid of all of them.
I dont remember them being stunted though.

 

When looking on the web, viruses seem to generally related to problems with more fully formed canes, not seen any mention about problems with new shoots like this.

Was thinking about taking it out, but thought someone here might know what it was, but better play safe, one for the dustbin.

 

Not used any weedkiller near it I presume?

 

Virus problems usually start on the fully formed canes (from aphids feeding on the soft young growth), but soon travels down to the roots. Virus-infected raspberries often look like that, with stunted shoots which appear as if they have chlorosis etc.
Or accidental weedkiller drift!
Viruses are really common on raspberries, so good plan to bin it.

 

If it is a virus I assume it was probably infected last year.

 

Not a weedkiller etc as we rarely use any and never on or near our veg/fruit beds.
The Rasps are well into the garden so no chance just they could be affected by drift from another garden.
