Blueberry leaves are dropping affected by disease

Yuliya starts with ...
Hi guys,
Misty and Biloxi dropping leaves affected by this yellow-orange spotted fungus (?). Soil is acidic and up until 1 month ago they were flowering like crazy and were very happy. The other varieties don't seem to be affected, despite the fact that they all are in a containers very close to each other.

I've removed the affected leaves, but I'm sure there is still plenty of that substance around, so it's probably going to come back...

Thanks everyone!

Once the rain stops I'm going to try diluted peroxide spray. Google search says it's a good natural fungal remedy, did you try anything yet Db? How are your blueberries doing?

Jantina says...
Down here the blueberries always lose their leaves in winter (deciduous)after the leaves go orange and yellow. Maybe check with where you got them to see if they lose their leaves up there too.

Db, it looks like some kind of rust.....the same as my frangipani gets on the back of the leaves at the end of summer. Just had a look at my blueberries, and some of the leaves are falling off, but none have that growth on them. Hopefully a spray of lime sulphur will get rid of it.

Db says...
I was reading about lime sulfur spray and everywhere it says 'Don't use lime sulfur spray on evergreens, as it might burn the fruits and leaves'.

So I'm not sure I should really use this on my tree at this stage, any suggestion?

Looks like blueberry rust. do a google on it. Should be able to treat it with mancozeb, lime sulphur and a few other products about.

Hi Yuliya, I applied lime sulfur spray as per above suggestion, It has surely helped to reduce the rust but its still there.. Most affected variety is now leaf-less but it has flowers.. Other 2 varieties are less affected and has few leaves remaining and some of them still have rust.. May be I need to spray it again... All three are flowering again but looks like most are getting dropped as I can see only few fruits forming.. I don't expect berries so soon anyway as all three are very young at this stage.. Not sure how I can encourage them to put on green growth instead of flowering.. I regularly gave them seasol and powerfeed as well but no new growth yet..
