Brugmansia Leaf Spot
Alternaria and Septoria are the leaf spots I've heard about that affect Brugmansia here in the USA. Mostly Alternaria. Septoria is the most common to the Solanacae family. Angular leaf spot is new to me.
Most of the leaf spot diseases are seedborne. They can be passed from person to person thru seeds. .... hmmmm. Something to think about :)
Thankfully I've never seen any of the leaf spots in person because I no longer grow anyones seeds except my own .... but since I'm bragging I'll probably get all the leaf spot diseases at once ... ha!
