Fungus/mildew on my angel wing?

#Begonia I was looking at my plant yesterday and noticed some white powdery spots on its stem and leaves. I’ve never had this on a plant before; is this a type of fungus or mildew, or something else? #AngelWingBegonia

I've never seen that before, but looks like mildew. I personally would clean it with gentle soap and dry it. Look to see if you have any questionsou have any questions have standing water in the pot or close by o. have any questions

I believe this is Powdery Mildew. This article will explain what that is and the prevention and treatment for begonias.
