Michelia Alba disease

Hi All,

We bought two of them 2 years ago, they were very healthy, large leaves, more branches and getting tall. And they were separated in different house, about last April 2012 one tree started getting dots on the leaves almost whole tree as seen below, we thought it would be OK to put them in one house which we did, and the second tree is getting the same which is telling me it is some kind of disease that can transmit from one to another :(. We decided to get rid of all affected leaves, but the young leaves still have the issue.
The good thing is that they are still alive and flowers too.
Not quite sure to get rid of it.
Any help/ idea would be appreciated.

Thanks

So sorry to hear about your trees.
Looks like spider mite damage to me.
Have you inspected the underside of the leaves for webbing?
Spraying Neem oil helps.

Hi Robert,

Thank you for your response, I did check if there was any insects or something suspicious, but no sign of insects nor web.
Regards

Perhaps some sort of leaf fungus? It doesn't look like spidermite damages to me. For preventive measure I would trim off the affected leaves and spray the whole plant with neem oil as suggested by Robert.

A solution of water/rubbing alcohol + neem oil is best. (1 pint of hot water, 1/2 teaspoon non-antibacterial soap , 1 teaspoon neem oil, and 1 pint of rubbing alcohol.)

Do this once every 5 days for about 2 weeks. Then monthly. For your monthly spray you can skip the neem oil. Michelia alba is tough so don't worry too much.
