Sudden problem on bean plants

[Goldie321]

My bush string beans were looking great and then this morning I'm seeing this. It did rain yesterday. No sun today and it's supposed to rain again. A few days back I sprayed with GardenSafe's Neem Oil. Only a few leaves seem to be affected - I'm hoping it isn't going to spread.

It looks like a fungal infection but I've never seen one like that on bean plants.
Here's a Handbook of Bean Diseases, don't see anything that exactly resembles what you've got.
Anybody else know what that is?

Agree with Ray, This is what I use.

I had this same looking thing show up on one of my pepper plants over night.
It hasn't spread or done anything for weeks now.
I figured it was some kind of insect or something.
I'm gonna go out and cut the 2 leaves off that it is on.

Maybe with the rain and unseasonably damp weather we've been having this is a fungus. Only a couple more leaves affected. Will spray again. The Neem Oil Extract I've been using is a fungicide as well. This is supposed to be our dry season here in Florida, but it hasn't been all that dry.

Neem oil works pretty well at inhibiting some fungal infections like Powdery Mildew. If it's a more difficult pathogen to control you might need something like a copper fungicide.
If you can identify what it is, it's easier to determine a course of action.
Are the infected areas dry or are they soft with a water soaked appearance? Anything different on the underside of the leaves?

If you see the pic you'll notice the leaf tips look soggy, but otherwise no. I picked off the 4 or 5 leafs it was on, and those had it to a much lesser degree.

Daconil - not available in Florida
The other stuff has some high toxicity concerns I don't like. We get our drinking water from a well on the property.

If you aren't familiar with the Field Horsetail, Print a picture of it from the link and take it to the meter readers at your electric department. They will have seen it growing in peoples yards whether they knew what it was or not. It looks that different from other plants. Or drive through older neighborhoods. Or check the big box stores, they sell the plants. Claud

I had four or five leafs that had that stuff on it. I clipped them off. Sprayed my Neem Oil yesterday. Today, after more rain, everything looks fine.
