Blueberry RedRingspot virus? (forum)

Kerry starts with ...
My blueberry plant that I have had for 12 months and which has been growing very well this season has these red areas just appear on the new leaves. The leaves were a bit yellow so I added some Ammonium sulphate to the soil because it didn't seem to be acidic enough.see photo showing no redness taken three days ago. I also put on some iron chelate solution. Now the red spots have appeared suddenly today mainly on the new leaves. What do you think is the cause? Or is it the treatment?I have only just bought two new blueberries plants and planted them.

Hi Kerry, your photo clearly shows the chlorosis of the leaves caused by alkaline soil. Adding ammonium sulphate is a good idea but it can take some time to take affect. I actually can't see red spots in the photo, but these may be blueberry rust developing as it was under stress. I hope this is helpful

Hi Kerry,

I don't see any red spots on leaves from the photo. However, if you do have then the problem could be rust/fungus disease caused by the pathogen. Please see the attached links below how to cure it. Cheers

Hi Pauline, Thank you for your response. The plant is looking great now and the two new ones are growing happily near it. I have found some pine needles to put around them and occasionally pour diluted remnants from the coffee plunger. Seems to be working.
Kind regards,

Kerry
