What are these spots on my Tiny Trev lilly pilly

[ethan_fr]

I recently picked up this tiny Trev Lilly Pilly for a bonsai from a nursery and had discovered many spots and holes on the leaves. I’m unsure what they are and how to fix it. Any help would be greatly appreciated

Hello @ethan_fr 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about lilly pilly.

Holes on the leaves is an indicator that it might have a pest eating the leaves. You'll need to investigate and have a look at the entire plant from top to bottom and under the leaves. It could either be an insect or a caterpillar. I can see some of the spots, but would it be possible for you post a closer photo of the damaged leaves with the spot on them?

Can you please tell us a little bit about the plant? Does it have a powdery texture on the leaves? Is there a distinct smell of mouldy wetness from the plant? Are there any black marks on the branches and is the soil under the plant damp or wet? 

Any extra information you can give us about your plant will help us figure out what's affecting it.

Hi @ethan_fr 

In addition to Eric's comments: In your top photo, I refer specifically to the upright leaf almost in the centre of the image with the spots surrounded by a purplish hue.  This looks rather like a fungal infection not dissimilar to myrtle rust, where spots develop on the leaf of a reddish-purple colour, then the centres die and eventually drop out, leaving small holes over the leaves. It's a bit hard to tell definitively from your photo, so a close-up would be terrific if you can manage it.

There's information on myrtle rust and how to treat it in the links that Eric has included in his reply.

Hello @ethan_fr 

Thanks for those extra pictures of your lilly pilly plant. It does appear to be myrtle rust with the telltale sign of a burned edge. Let me call on @Noelle so that she can see the picture as well. 

Myrtle rust can be controlled in the home garden with applications of copper fungicide or mancozeb. 

Please make sure to wear personal protection such as gloves, goggles and a mask when using this product. Please remember to follow all the safety precautions printed at the back of the container.

If you need further assistance, please let us know.

Agreed, @EricL . Looks to be myrtle rust to me.

I also noticed these white spots on the underside of the leaves. Just wondering if they affect the diagnosis?

[EricL]

HI @ethan_fr 

I believe they are part of the effect of myrtle rust. I propose using the recommended remedy and observing the plant for the next few weeks. If the white spots remain or other symptoms emerge, please take a close-up photo of the leaves and share it with the community.  

If you need further assistance, please let me know.
