Can someone please tell me what disease is affecting my navel orange tree? The new leaves are deformed and curled.

Thanks.

While we're guessing, how about leaf miner?

In any event, can we try an image or two with a different angle to fully visualize the distorted leaf/leaves?

ronalawn82,

Thanks for posting the link, it's very informative, didn't know that there are so many viruses infecting citruses:(

Thanks for the new image.

I doubt the problem is due to a virus or other disease. I suspect water shortage, even though it may have been only brief.

Some questions for you:
- How long have you had the tree?
- How widespread is the damage on your tree? (e.g. one sided; all over; or?)
- If other leaves are damaged, are the tan areas larger or smaller?
- How do you water the tree? Sprinkler, handheld hose, or ?
- How often do you water? (How do you determine it's time to water?)
- How do you decide the tree has received enough water at an individual irrigation?

Hello Jean,

Glad to know that it's not virus.

Thanks for the new image.

I doubt the problem is due to a virus or other disease. I suspect water shortage, even though it may have been only brief.

Some questions for you:
- How long have you had the tree?
2+ yrs may be, it's planted by previous owner.


- How widespread is the damage on your tree? (e.g. one sided; all over; or?)
only on new growth

- If other leaves are damaged, are the tan areas larger or smaller?
I think about the same.

- How do you water the tree? Sprinkler, handheld hose, or ?
It got some sprinkler spray every other day and I try to hand hose it everyday.

- How often do you water? (How do you determine it's time to water?)
- How do you decide the tree has received enough water at an individual irrigation?

I will give it more water daily and see if the issue will go away, thanks.
