Rasberries in trouble...
 

Hello,
The leaves on my raspberry plants have started to turn a very bright yellow - but only in patches. Many of the plants maintain a vigorous green leaf. Fruit growing on both yellow and green areas appears the same and OK. These are late summer/autumn raspberries. they were well mulched with rotted stable manure in April. ome were transplanted to other areas of my allotment, thesae are also yellow. June fruiting raspberries alongside are completely unaffected.

Any ideas/help please?

Could be a manganese deficiency if you are lucky. Sorry about the
organic bit, if it is a lack of manganese you'll have to get a
supplement or find a source of crushed roc which contains it.

(That's manganese, *NOT* magnesium!)

Open the creaking gate to make a horrid.squeak, then lower the foobar.

thanks - any ideas why this would happen to the autumn fruiting raspberries, whilst the summer fruiting rows alongside are unaffected?

No, but it may be less tolerant of the deficiency - if indeed it is that.

Just to be sure, google for mosaic virus - but your description didn't
ring alarm bells.
