How to treat Silver princess eucalyptus fungal infection?

[DanD1]

Hi everybody - Am looking for some assistance re a silver princess gum issue as our silver princess looks to have quite a bad infection, I'm guessing fungal? 

It is a mature tree about 5m tall, but the affected leaves are quite widespread and reach high up the tree to near the top. It has been dropping leaves quite a lot for a while.

Would be eternally grateful if anybody could recommend an appropriate treatment.

Thanks - Dan

Hi @DanD1,

A couple of products you could consider are Yates 200ml Liquid Copper Fungicide and Yates 500ml Anti Rot Fungicide. As mentioned by @gamefisherman, our gardening experts in-store are also available to provide recommendations.

Appreciate you taking the time to help and very grateful for the advice! I found a couple of blogs that said PhosAcid 200 and Mancozeb are good so will start there!

Nice one. Good luck with it mate.

Ooh I think my young Silver Princess has the same ailment but mine also has a very unhealthy looking stem!

Have you tried those two products as yet? Anything fungal will require persistence and multiple applications but I’m keen to know if you’ve noticed any improvement already?

Hello @anch 

Welcome to the Bunnings Workshop community. It's wonderful to have you join us.

Let me tag @DanD1 to make them aware of your questions. I'm sorry to hear that your eucalyptus has a fungal infection as well. It would be interesting to find out from Dan what the results were after spraying the plant. But if you look at the reviews of the Yates 200ml Liquid Copper Fungicide, you'll see that they are quite positive and the spray effective.

If you do decide to use the copper fungicide, please remember to wear personal protection such as gloves, goggles and a paint mask. Please make sure to follow all the safety guidelines printed at the back of the container.

If you have any other questions we can help with, please let us know.

Hi Eric - Thanks for thinking of me! My tree has been quite affected with probably 80% of leaves browning so I may have gotten in to late. I have been using the Yates root rot and it seems to have halted things in the remaining leaves but I'm not sure the tree will come through unfortunately. I may try add this other fungicide to see if it helps

Hi, I have the same problem I think but I don’t think mine is now fungal as there are small caterpillars and larvae that are living inside those whitish brown pimple type of things that are attached to the tree branches and now killing my tree. Out of interest did you end up spraying it with any insecticide? Did it work? Any help would be greatly appreciated.
