My starts of Mexican milkweed plants seem to be a magnet for every type problem. Yellow aphids I decided to leave alone. Other things I don't know the name of. Now powdery mildew so bad I decided I had to do something. Was going to try the baking soda, veg. oil and water treatment but thought I better look closely before spraying and found this new item that looks like an egg of some type. So do I spray or not?
