How to treat my new Mulberry that has leaf rust?

I noticed on my new Mulberry plant there were 2 leaves with rust patches and that is 10% of the total foliage.  If it is caused by some form of disease, i hope to find a cure before it infests the plant and the rest of my garden. 

Thank you.

Re: How to treat my new plant that has leaf rust

Hi @acb,

 

I'm sorry to hear you are experiencing issues with your new Mulberry plant. Did you purchase it from us? If so, we have a perfect plant promise. All our plants are guaranteed for 12 months, so if you're not 100% happy, return your plant (with receipt), and we'll refund it. The only exceptions to this guarantee are flower and vegetable seedlings and our range of potted colour.

 

If it has a disease, then the symptoms shown here would be closer to leaf spot rather than rust. Leaf spot is characterized by brownish necrotic irregular spots appearing on the leaf's surface. These brown spots classically form into halo-like patterns (marked in your image below), and advanced cases feature splits on the leaf's perimeter. In contrast, rust manifests as circular pinhead-sized brown eruptive lesions on the leaves. 

 

The best approach to treating this plant would be to remove the affected leaves, which you have already done, and place them in your hard rubbish bin. I'd then suggest you apply a copper-based fungicide to the plant.

 

Water the plant only at its base, avoiding the leaves, and do so in the morning to allow the foliage time to dry completely before nightfall.

 

Please let me know if you have further questions or if your plant does not improve.

 

Mitchell

G’morning Mitchell

 

I really appreciate  Bunnings’ policy to accept return under the circumstances.    I thought about it and decided to bring it back Bennett’s Green Bunnings where I bought it.  It will be great if I can exchange it with another healthy Mulberry plant if you can find one as I found signs on other leaves this morning.  I hope to start afresh with it as I do like the idea of harvesting the delicious fruit from my backyard.

I agree with @MitchellMc that this is unlikely to be 'rust' on your Mulberry.

Thank you, Rob.  I believe that is the case after seeing Mitchell's photos comparing the 2 different cases.  I also went and bought Yates liquid copper as he recommended as it treats many diseases as the label suggests.
