Hi
This is happening on a juniper of mine, nobody seems to be able to tell me what is attacking it.
any help appreciated please.
Thanks
Pete
It basically justs starts turning brown, and dieing back slowly ,thought I had got hold of it last year with lime sulfer but it has started again on the new grownth from where it died back last year.the tree other wise is pumping with new growth on other branches.

Hoping others will chime in on this one...I believe it is called Juniper Blight - a fungal infection that gets into the roots and wood. Hard to treat but some have had success with Copper Oxychloride..
A mate of mine has lost a large old tree despite using the Copper - parts of the tree dying back and just continuing until there's nothing much left. Other's have also lost entire tree's - old ones...It's bloody debilitating and frustrating. I've been fortunate until now and not seen it although I've only just noticed a little section of dieback on one of my Shimpaku's so am very paranoid. I'm going to hit them with the Copper as well....
I may be wrong with your diagnosis but it's a major problem here in Vic. and effecting the Nursery trade as well.

Yes bunch of discussion on this topic on the forum.
I fear the worst here.. Bodhi knows a fair bit about this although i still don't think he has found a solution..
Good luck and please share any progress with others!

I second copper oxychloride. Had good results with it. do not cut off infected areas. Spray weekly for 6 weeks then remove any visibly affected areas. For some reason if you cut off the effected branch before spraying it is not as effective. I bought a juniper from a nursery and a few weeks later started showing signs same as yours, two others on the same bench started going brown also. Had no idea what it was or how to treat it. We had a demonstrator at our club who recommended the above. I followed those instructions and got rid of it totally. Saved my two trees with no ill effect, lost one branch on the nursery bought tree (was gone before I sprayed) but saved the rest of the tree.
Good luck and get on to it straight away or it WILL KILL your tree.

Gday Josh... what product did you use.. eg, Yates, Manutec etc..?
Like we discussed the other day, even if my tree's are showing the slightest symptoms, I want to give them a treatment....just in case..

[Pete348]

Morning,
Thank you so much! A friend of mine told me to post on here and actually said you might get some someone from down south who has seen what I have, apparently its not very common up here, Im very grateful for your knowledge on this. I will be at Bunnings as soon as it opens this morning.
Just tell me, its getting pretty warm up here right now, does the copper oxychloride burn with heat like other products such as lime sulfer please?
Thanks again!!!
Pete

I don't think there is any permanent fix identified yet.

It's been a recent topic of discussion at my club where I was recommended white oil. I tried it - it seems to slow things down but it comes back.

I've found it only happens on trees in my garden which I haven't fertilised as strong and as regularly as others.

I'm curious about trunk size of your tree - how big is your trunk and what is the size of the affected branch?

Hi Rob, I used the Yates one. Mix at a rate of 2 teaspoons in a watering can.

Hi Daluke
I have attached a pic of the tree, I recon its a about 2 -2 1/2 ft tall and the Base is thicker than a can of redbull
I just got back from Bunnings and will give my first spray in a minute.,

Beautiful tree mate. I hope it's nothing and just the tree shedding old needles.

[treeman]

This is a real concern. I never saw it twenty years ago but I have lost several good trees from it in the past 2 or 3 years. I now spray copper regularly as a prophylactic. I would like to find a more organic alternative. Some kind of biological control would be great! I also wonder whether there is some kind of insect (or mite) as a vector?
Another thing. Many pests and diseases over-winter on different species - weeds etc. It might be worth spraying everything?

[Daluke]

Treeman, has your treatment worked?

Treeman, has your treatment worked?

I don't seem to have any new outbreaks but still some older plants with it.

Update,
Hello
Ok so I have been spraying every week, I take the tree out of the sun and spray it under the house I have left it for a couple of days and then put it back in the sun after giving the follage a good drench.
The tree stopped getting more die off after a week. I did not pick any of the dead follage off, I just left it as it was.

I am into the 5th week and next week will pick all the brown off to really monitor any die back. I am very grateful for the feed back and replies so thank you guys! I hope this can help other too.
