Pest or ????

[Worth1]

Master gardeners are like doctors.
Some are fantastic and you can learn a lot from them like KarenO and others are not so good.
Then you have some younger ones that I know that ask older folks like me questions these are the smart ones.
They rely on people that are older to learn from.

I would like for Karen to see our stick bug invasion we have from time to time.

I have no real proof what is on the plant.
Can you set the camera on macro and take a shot or two?

Cheeseweed leaves are an excellent lettuce substitute, edible, and more nutrient dense than the stuff in the expensive salad blends. They can be eaten raw or cooked in spaghetti sauce, etc. And no charge for the Rust

I'm a nurse not a doctor

Without holding it in my hand I am as sure as I can be from a photo that it's rust.
Like Worth said, I have no proof though.
Getting rid of it will be a good thing regardless. Labour intensive for sure, but bagging it up and carting it away is still the best option be it beast or fungus.

Karen, I was thinking that taking a picture of one certain infected leaf one day and then another picture of that same leaf the next day might show if the spots are moving? Just an idea.

See, this is why I like Canada. No stick bug invasions here Worth it's too darn cold

Went out and put a piece in a baggie... think my photo shows better today. I scratched it with a butter knife. I'm still confused but I know whatever it is...it is nasty!

Yes, it's cheeseweed. I'm gonna pass this time LOL!

[Stvrob]

can that rust spread into vegetables? Or is it specific to its host?

[Worth1]

Now I think I know what rust it is.
Almost postive.
It is Puccinia malvacearum a rust that forms on mallows and hollyhock.

I was trying to copy and paste the email but cant do it. They said there are insect droppings , scale and some eggs but they don't know what the eggs are from.

[socalgardengal]

Exactly what it looks like to me worth!

Only to the Malvaceae family as far as I can tell.

KarenO, be kind to "y'all Southerners". We supported your initial suspicion without taking credit for it, and confirmed it by identifying the Cheeseweed host of the Hollyhock Rust.
Love and kisses
