Avocado Diagnosis Leaf Rust

[Yook]

Hi Everyone, I searched and didn't have very much luck finding anything similar to what I'm experiencing. Both my avocado trees have this brown rust on their leaves, originating from the center vein it seems. It doesn't rub off. Doesn't look to be doing a ton of damage but it is progressing and wondered if I should be worrying. The trees are just about to flower and seem healthy otherwise. I did see similar leaf markings on a avocado at a nursery down the street as well.

Turns out the marking is from red spider mites. Seems to be getting a little worse. There is a large hedge about 30 feet away off my property that appears to be covered as well. Is this something I should try to let resolve itself or should I be worried? I’m hesitant to spray neem pr anything while flowers are open. Anyone had luck buying ladybugs? Thanks much

Don’t worry about it. Happens every year.

Really appreciate it Squam. Some of the leaves near the top are falling off from damage but I'll give it a week or two before I start spraying. Tree has been really healthy otherwise so it should be able to resist I'd hope.

These leaves should soon fall.  Shiny new ones and bloom will replace them.

Thanks Guanabanus. This guy is a brogdon and has been blooming for a couple weeks now but has dropped all of its flowers so far that have opened. I know they're sensitive to temperatures and you can get unlucky with the male and females not being open at the same time. Have you all had to resort to hand pollinating before? Have you had luck doing so?

I never tried that, nor have I heard of it.
